DFW HAS POSTED THE CATCH AND KEEP RECOMMENDATION DUE TO SUMMER WATER QUALITY. 
This is quite normal posting to preserve the fishery.  It’s nothing new and it helps greatly. 

Surface temps showing on 9-23 were 65-66F.  We’re dropping but very slowly.  We have 40ft of water column to cool off.  Spring water gyres showing 57- 61F-ish. Water remains greenish, but clarity is fairly good at seeing bottom at 10ft deep.  Once we start seeing low to mid 60’s, we’ll see that green turn to brown….normal fall pattern.  We are cooling down and into the 30’s overnight.  This is causing some normal fall patterns of fog on the water in the morning.  Days have been beautiful since the storms passed and they were beautiful as well and added almost an inch of rain to our monthly total at 2.71”.  Surface weeds are coming and going, mostly scattered but there’s a few just about anywhere.  Just enough to keep an eye on your line and check your bait periodically.  Weeds are torn up by birds for the most part. Later in fall, the weed/moss beds (what is left of them) naturally shed like leaves falling from trees and the mud hens come in droves and really help get things weedy! 

The difference throughout the drought and low water has been the dissolved oxygen level, washed out thermocline, cyanobacteria cautions and green water.  However, at around 68F throughout the water column the green will begin to turn to brown and by 64/65F its well on it’s way…just hang on, we’re just a few weeks behind as we have been since the drought years.  Not time to catch and release yet!   The clarity of the lake has improved quite a bit, officially, we have 9-10ft so that’s much better than 5-6ft. Eagle Lake rainbow trout are use to 70’s and as long as the oxygen level is sufficient, they will be there.  However, in my experience they do not release well at all in summer and in surface temps above 68F.  They hemorrhage upon being hooked & I wait until the lake temps and pH settle down a bit.  It won’t be too much longer.  Please help us preserve the fishery by keeping any trout you catch.  Springs are holding surface temps around 61F…some 56-59F when you find em.   Some tests (7-12) of which has warranted the water board to post a caution for HAB on July 19th.  We didn’t see anything concerning enough to collect at Merrill in August tests.  Gov satellites show a good bloom up in the north basins on the third week of August, but in locations only cattle have been able to access.  Mostly in the swampy shallow, quiet bays.  Just use common sense. We found it south of Pelican Pt to the north basins but not so much in the deeper, traverse-able channels.  Moves with the wind.  Everywhere we’ve fished has been pretty clean on the surface except for a few weeds, some gunk was present on the west side, but winds shift it.  It changes daily.  Visibility was 5-6ft deep using official secchi dish on 8-9.  I was hoping for better than that!  There’s also been some foam lines after windy days which have not had much if anything except some particulates.   Just be smart right now.  Weeds are starting to pop up.  Check your lines.  Fish don’t eat a lot of salad.

Stay safe out there.   Kayakers…..wear the dang life jacket.  Why…..well, if your rods are tethered and your treading water….you’ll end up winding line around your legs.  This did happen and fortunately our friend was rescued by a local guide.  Had to be cut out of the line.  So, let’s actually abide by the rules this season.  It’s going to be a tough one on everyone.

Scroll down this page for a list of elevations back to 2010. We got through launching at the south end low water ramp thanks to Scott building up a nice rock ramp below the cement.  Our worst enemy for launching in gravel and silt IS PEOPLE POWER LOADING and OFF LOADING BOATS! Doing this builds up a shoal of fines that accumulate in the launch channel and create a shallow rise just beyond it.   Also dislodges rocks at the end of the cement causing a deep drop off.  Please note that this is detailed in the Boating and Waterways boaters card course and test.  We have only one launch to serve the lake…please don’t help screw it up before it screws itself up.  LoL. 

Expect some unmarked natural rock piles to be closer to the surface.   

During this “climate change” I have not seen our water temps rise above any high temps I have seen in all my years up here….However, our last good icing over was in 2011.  In higher water levels, we would see summer thermoclines keep fish deep for a month and a half if not longer.  Drought years: Thermoclines form briefly and dissipate after a week to 3 weeks before there’s 1F to 3F difference between the surface temps and 45-50ft in July/August and dissolved oxygen levels are higher and in warmer temps.  This has a terrible affect on the long term survival of a released trout in this high pH lake.  The lake is generally in the mid to high 50’s on opening weekend, hit’s 74-75F on the surface at the peak of summer before cooling down.  Cool down generally is gradual and begins in August. Sitting at around 65-66F on 6-29-22.  In sync with most every year.

HERE IS THE CONSERVATION PLAN TO RESTORE THE NATIVE SPAWN OF EAGLE LAKE TROUT, RESTORE PINE CREEK AND RESTORE AND MAINTAIN THE GENETICS!  WORK HAS ALREADY BEGUN AND DFW HAS MADE CHANGES IN HOW THEY MANUALLY COLLECT AND FERTILIZE EGGS.  USFWS DETERMINATION SHOULD BE OUT BY THE END OF THE MONTH.  One female to one male for artificial spawn since 2015.  The quality of the fish is improving, extra bones reduced and exponential numbers of white flesh reduced to more normal levels.  In every red fleshed salmonoid there’s a natural occurrence of white meat. Good to see the white fleshed fish reducing and our deep red flesh re-emerging as dominant.  The white flesh is still Eagle Lake trout, just as a white fleshed salmon is still a salmon.  I don’t have a problem eating either.
 
CHRISTIE DAY USE AREA HANDICAP RAMP TOWARDS THE LAKE IS IN SUCH DISREPAIR THAT IT CAN HANDICAP YOU IF YOU AREN’T ALREADY IMPAIRED.  THERE ARE A LOT OF TRIP HAZARDS.  We walk on the vegetation beside the ramp.  There are several trails.  Doubtful we’ll see any repairs to existing handicap access.
 
LAKE ELEVATIONS
 
2022 LAKE ELEVATIONS:
9-2-22: From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement, taken earlier today, show that the lake has dropped 0.46 ft. (5.52 in.) over the past month.  This puts the lake level at an elevation of 5090.79 ft., which was measured at the low-water ramp at Gallatin.  This is roughly 20 inches lower than it was at one year ago at this time.  I say “roughly” because we didn’t have a measurement for September one year ago.”… Publishers Note: 5090.61 is our 2015 low water which reached the low water elevation dating back to the late 1930’s.
7-29-22: From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.65 ft. (7.8 in.) over the past month.  This puts the lake level at an elevation of 5091.25 feet, which was measured at the low-water ramp at Gallatin.  This is 1.22 ft. (14.6 in.) below where it was at one year ago at this time.” Publishers Note” this is fairly normal evap rates for July and August.  It will slow down.
6-29-22: From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement, taken a few days early due to the upcoming holiday, show that the lake has dropped 0.28 feet (3.4 inches) over the past month.  This puts the lake level at an elevation of 5091.90 feet, which was measured at the low-water ramp at Gallatin.  This is 1.01 feet below where it was at one year ago at this time.”
6-1-22: “The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.46 ft. (5.52 in.) over the past month.  This is disappointing to say the least, especially this early in the summer season.  This puts the level at 1.15 ft. (13.8 in.) below where it was at one year ago at this time. The elevation of the lake is currently at 5092.18 feet as measured at the low-water ramp at Gallatin.”
5-2-22:  From Don Willis, Lassen County Surveyor: …”Eagle Lake measurement this morning show that the lake has risen 0.10 feet (1.2 inches) over the past month.  This small gain puts the total gains for the season (since last November) at 0.97 feet.  Unfortunately, this is still 1.04 feet below where it was at one year ago at this time.  The elevation of the lake is currently at 5092.64 feet which was measured at the low-water ramp at Gallatin. Publishers note: I suspect we’ll see a more significant drop for June measurement.  We had high winds for days without much let up on this day.  The photos sent show it.  We had 0.81” of moisture in April.  I suspect a good surge on this day.  We see this surge all the time at the north basins.  We’ll see!
4-4-22: From Don Willis, Lassen County Surveyor: …”The elevation of the lake is currently 5092.54 feet, as measured at the low-water ramp at Gallatin, which is 1.38 ft. (16.56 in.) below the level one year ago at this time.”… Publishers Note: Doesn’t appear that its going to get any higher this year.  Pretty much as high as we’re going to get, now evaporation kicks in.
3-1-22: From Don Willis, Lassen County Surveyor; “The results of our monthly Eagle Lake measurement this morning show that the lake has come up 0.07 ft. (0.84 in.) over the past month.  The elevation of the lake is currently at 5092.57 ft., as measured at the low-water ramp at Gallatin, which remains 1.42 ft. (17.04 in.) below the level one year ago at this time.” “….”
2-1-22: From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement this morning show that the lake has come up 0.12 ft. (1.44 in.) over the past month.  The elevation of the lake is now at 5092.50 feet as measured at the low-water ramp at Gallatin.  Unfortunately, this still remains 1.49 feet below the level one year ago at this time.”…. Publishers Note: it isn’t over just yet, but it’s not looking good.  We need last years elevation just to keep launching very carefully at the low water ramp thru the year. 
1-3-22: From Don Willis, Lassen County Surveyor; “The results of our monthly Eagle Lake measurement this morning show that the lake has come up 0.42 ft. (5.04 in.) over the past month.  The elevation of the lake is now at 5092.38 ft. as measured at the low-water ramp at Gallatin.  This remains 1.5 ft. below the level one year ago at this time….”
 
2021 LAKE ELEVATIONS:

12-1-21: From Don Willis, Lassen County Surveyor:  The results of our monthly Eagle Lake measurement this morning show that the lake is at the exact same level it was at a month ago.  The elevation of the lake remains at 5091.96 feet as measured at the low-water ramp at Gallatin.  Unfortunately, this is 1.76 ft. (21.12 in.) lower than it was one year ago at this time……”

11-1-21: From Don Willis, Lassen County Surveyor:   “…The results of our monthly Eagle Lake measurement this morning show that the lake has risen 0.29 ft. (3.48 in.) over the past month.  This is the first increase since last February!  The elevation of the lake is currently at 5091.96 feet as measured at the low-water ramp at Gallatin which is 1.78 feet lower than it was one year ago at this time….”  Note: pretty close to the amount of moisture received from the first storm!

10-1-21: From Don Willis, Lassen County Surveyor:  “The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.80 ft. (9.6 in.) over the past two months.  We missed last month’s measurement thanks to Covid. The elevation of the lake is currently at 5091.67 feet as measured at the low-water ramp at Gallatin which is 2.25 feet lower than it was one year ago at this time.  Unfortunately, this is approaching the low point that was reached back in December of 2015 when the lake was at an elevation of 5090.54 feet.”

8-3-21:  From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.44ft (5.28″) over the past month. … The elevation of the lake is currently at 5092.47ft.  … 25″ lower than one year ago at this time.” …

7-6-21: From Don Willis, Lassen County Surveyor: “The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.42 ft. (5.04 in.) over the past month.  This is a little over 25 inches lower than it was one year ago at this time. The elevation of the lake is currently at 5092.91 feet as measured at the low-water ramp at Gallatin. ….”

6-2-21:  From Don Willis Lassen County Surveyor: …”The results of our monthly Eagle Lake measurement this morning show that the lake has dropped 0.35 ft. (4.2 in.) over the past month.  This is nearly 26 inches lower than it was one year ago at this time.The elevation of the lake is now at 5093.33 feet as measured at the low-water ramp at Gallatin. 
4-30-21:  From Don Willis Lassen County Surveyor:  “The results of our leveling this morning show that the lake has dropped 0.24 ft. (2.88 in.) over the past month.  This is not good news for the month of April where an increase is typically observed. …. The elevation of the lake is now at 5093.68 feet, as measured at the low-water ramp at Gallatin.  This is 2.13 ft. (25.56 in.) lower than it was one year ago at this time.” (Note: Nov 2020 elevation was 5093.74ft)

4-2-21:
From Don Willis, Lassen County Surveyor: ….”The level was at an elevation of 5093.99 feet last month and was found to be at 5093.92 feet this month, a difference of 0.07 ft. which is under an inch.  The small difference is likely due to different estimations of where the water level was thought to be by the rodperson.  …..The level has only risen 0.2 feet (2.4 inches) since the beginning of January and Pine Creek is not currently flowing.”
3-2-21: From Don Willis, Lassen Co Surveyor: …”The level was at an elevation of 5093.99 feet last month and was found to be at the exact same elevation this month.  Unfortunately, the current level is 1.78 feet lower than it was one year ago at this time.
2-1-21:  From Don Willis, Lassen Co Surveyor:  …”The level is currently at an elevation of 5093.99 feet which was measured at the low water ramp at Gallatin.  Unfortunately, this is 1.89 feet below where it was one year ago at this time.”…
12-31-20: from Don Willis, Lassen Co Surveyor: …”The level is currently at an elevation of 5093.86 feet which was measured at the low water ramp at Gallatin.  Unfortunately, this is 1.93 feet below where it was one year ago at this time.”…
 
2020 LAKE ELEVATIONS
 
12-31-20: From Don Willis, Lassen County Surveyor: “The results of our leveling this morning at Eagle Lake show that the lake has come up 0.14 ft. (1.68 inches) over the past month.  This is the first increase we have seen since last spring.The level is currently at an elevation of 5093.86 feet which was measured at the low water ramp at Gallatin.  Unfortunately, this is 1.93 feet below where it was one year ago at this time.” Note: we only had 0.71″ of moisture in December.  LoL  Magic water.
11-2-20:  From Don Willis, Lassen County Surveyor:  “…..the lake has dropped 0.18ft (2.16 in) over the past month.  this puts the current elevation at 5093.74ft as measured at the low water ramp at Gallatin.  The level is currently 1.82ft (21.84 in) below where it was one year ago at his time.” …
10-1-20:  From Don Willis, Lassen County Surveyor:  “The results of our leveling this afternoon at Eagle Lake show that the lake has dropped 0.25 ft. (3 in.) over the past month.  This puts the current elevation at 5093.92 ft. as measured at the “new” boat ramp at Gallatin.  The level is also currently 1.89 ft. (22.68 in.) below where it was one year ago at this time.”  Val’s note: February 20th ish 2017 the lake was at the same elevation.  Before that was Sept 2, 2013, 2015 was our lowest year at 5090.61ft Oct 1, 2015.
9-3-20: From Don Willis Lassen County Surveyor:  “The results of our leveling this morning at Eagle Lake show that the lake has dropped 0.43 ft. (5.16 in.) over the past month.  This puts the current elevation at 5094.17 ft. as measured at the “new” boat ramp at Gallatin….The level is also currently 1.71 ft. (20.52 in.) below where it was one year ago at this time.
8-3-20: From Don Willis Lassen County Surveyor: “The results of our leveling at Eagle Lake show the lake has dropped 0.42ft (5.04″) in the last month.  Current elevation is 5094.60ft.  The level is also currently 1.77ft (21.24in)  below where it was one year ago at this time
7-1-20: From Don Willis Lassen County Surveyor:  “The results of our leveling this morning at Eagle Lake show that the lake has dropped 0.47 ft. (5.64 in.) over the past month.  This puts the current elevation of the lake (measured at the Gallatin ramp) at 5095.02 ft. The current level is also 1.72 ft. (20.64 in.) lower than it was one year ago at this same time.”
6-1-20:  The results of our leveling this morning at Eagle Lake show that the elevation has dropped 0.32 ft. (3.84 in.) over the past month.  This puts the current elevation at 5095.49 ft. as measured at the “new” boat ramp at Gallatin.  The current elevation is 1.71 ft. (20.52 in.) lower than it was one year ago at this time.  Overall, the lake only came up about three inches this year during the wet season.  So, that has already been lost in just the past month…
5-1-20:  Officially the elevation is 5095.81, 1.34ft lower than it was last year at the same time.
4-12-20: Unofficial elevation measurement at Spalding ramp markers:  5095.96ish.  About 2 1/2″ higher than in March.  Corresponding closely with local precipitation.
3-2-20: As per Don Willis the lake had gone down 1.3″ (0.11ft)  over the last month.  0.37′ higher than 2019 at the same time (4.4″) 5095.77ft 
2-4-20: As per Don Willis Lassen County Surveyor “…the lake has only come up 0.09ft (1.08″) over the past month…1.2ft higher than it was one year ago at this time.  3.84″ increase since Dec.”  5095.88ft.
1-2-2020: As per Don Willis Lassen County Surveyor: ” …the lake has risen 0.2ft (2.4”) over the last month.  …. 5095.79ft which is 1.46ft higher than one year ago at the same time.”
 
2019 LAKE ELEVATIONS
12-2-19: From Don Willis Lassen County: Excerpt: “We found that the lake has come up 0.03 ft. (0.36 in.) over the past month.  The elevation of the lake is currently at 5095.59 feet as measured at the “new” boat ramp at Gallatin.  This elevation is 1.37 ft. higher than it was one year ago at this time.” (Note: 1.26″ of moisture from the recent snowfall melt)
11-1-19: From Don Willis Lassen County: Excerpt ”The results of our live lei great this morning at Eagle Lake show that the level has dropped 0.25ft (3”) over the past month.  5095.56ft current: 1/38ft (1 ft 4 1/2”) above where it was at one year ago at this time.”
10-1-19:  From Don Willis Lassen County: Excerpt  The results of our leveling this morning at Eagle Lake show that the lake dropped only 0.07 ft. (0.84 in.) over the past month.  The current elevation is at 5095.81ft.  1.54ft higher than one year ago.
9-6-19:   From Don Willis Lassen County surveyor:  “The results of our leveling this morning at Eagle Lake show that the level has dropped 0.49 feet (6 inches) over the past month.The current elevation of the lake is at 5095.88 ft. and fortunately is 1.26 ft. above where it was at one year ago at this time.”
8-2-19: Don Willis, Lassen County Surveyor: “The results of our leveling this morning at Eagle Lake show that the water level has dropped 0.37 feet (4.44 inches) over the past month.  This puts the elevation at 5096.37 feet as measured at the “newer” boat ramp at Gallatin.”
7-8-19: The results of our leveling yesterday afternoon at Eagle Lake show that it has dropped 0.46 ft. (5.52 in.) over the past month.  This puts the lake at an elevation of 5096.74 ft. as measured at the deep water boat ramp at Gallatin.  The good news is that the current elevation is 1.06 ft. above where it was at one year ago at this time. Since we don’t have but two ramps, I assume he meant the LOW WATER ramp since that was his photo.  LoL. 
6-4-19: The current elevation of the lake is at 5097.20 feet which is 1.31 ft. (1 ft, 3 in.) above where it was at one year ago.  The results of our leveling this morning at Eagle Lake show that the level has come up 0.05 ft. (0.6 inches) over the past month.  This was surprising to me given that Pine Creek is still flowing and there have been thunderstorms in the area for a while now. (1.03” of rain the last two weeks of May might have helped. LoLV)
5-14-19 Pine Creek flow was around 46cfs
5-6-19 Pine Creek flow around 69.1cfs. Official Lake Elevation by Don Willis Lassen County Surveyor is 5097.15ft.  Which is up 1.07ft for April. Wow, the math works with the cfs and duration. Lake up 2.96ft since Dec 2018. We haven’t seen 5097’s since 2011.  However, at the flow rate of Pine Creek it’s doubtful the lake will continue to rise any higher but we may stave off a little evaporation.  Flow will be fine for the fish upstream for a while.  Not an “epic” winter as many people thought.  I remained conservative as I have collected numbers for years and numbers matter, the math works.  We remain 10” short on rainfall from 2017, but I sure would like to see some before summer.  Only a good rain will help the lake rise higher, immediately by the way. 🙂
5-1-19 Pine Creek flowing around 145cfs.  Lake is pretty much done rising.  No change this week.  County will be checking elevation this week.
4-22-19: Unofficial check at 8:45AM indicated the lake was 5097.035ft.  County will measure around the first of May. But my estimate is that we’ve seen a little over a foot increase this month so far, which is pretty right inline with the cfs of Pine Creek. Almost 3ft gain since November. Hope to see a few more inches before it’s over for the season. 🙁  We’ll see.  As the weeks warm up, flow could remain fairly steady.
4-13-19: Unofficial check today indicated the lake was around 5096.68ft which is getting very close to 2017 high water mark. New ramp photos in Spalding in 2019 ramp album in the Photo Gallery.
4-2-19: Lassen County official measurement from Don Willis: “The results of our leveling this morning at Eagle Lake show that the lake is at an elevation of 5096.08 feet which is 0.68 ft. (8.16 inches) above where it was at a month ago.  This is just slightly higher than it was one year ago at this time (5096.08 ft. vs 5095.95 ft.).”
3-29-19: Unofficial check at Spalding ramp markers 5095.96ft.  County will most likely officially measure sometime next week. Papoose and Merrill are also flowing along with Pine Creek.  CFS’s in Pine Creek not stellar but fair.  Last check on 3-27-19 was at 145cfs.  Still up and down.
3-19-19 Unofficial check at 5095.62 (Pine Creek picking up a little, but still not gushing)
3-4-19:  Official elevation from Don Willis Lassen County surveyor: The results of our leveling at Eagle Lake show that the lake has come up 0.71 ft. (8.52 inches) over the past month.  This puts the elevation at 5095.40 ft. which is just slightly below the elevation it was at one year ago at this time (5095.46 ft.). (7.04″ of Moisture in Spalding since last elevation check, a bit more down south, good increase with local precip).
2-1-19 Official Lassen County Surveyor Don Willis “lake elevation 5094.69 ft.  Up 4.3″ over a month.  0.71ft (8.5″) below where it was at one year ago.” Note that January precipitation was 4.71 inches as per my weather station in Spalding.
1-4-19 Official Lassen County Surveyor Don Willis lake elevation 5094.33ft.  Up 1.32″ in the last month. 10.56″ below last year at the same time. (Moisture in December in Spalding was 1.67″ as per my weather station at home)
 
2018 LAKE ELEVATION
 
11-30-18: Official lake elevation at 5094.22ft: 0.36″ above last month (11.64″ below last year at the same time.)
11-2-18: Official lake elevation at 5094.18ft, only lost a little over an inch in October (perhaps that 0.96″ of rain around the first of the month helped out a bit. 10.5 inches lower than last year at the same time.
10-1-18: Official elevation at the Low Water Ramp at Gallatin 5094.27ft.  4.2 inches lower in the last month.  11.3 inches lower than last year at the same time.  Basically around 3 3/4ft above our lowest point. Almost 2ft lower than our highest point this year.
9-5-18: Official elevation at the Low Water Ramp at Gallatin The elevation of the lake at the new Gallatin ramp is currently at 5094.62 feet.  This represents a drop of 1.06 feet since our last measurement on July 2nd.  The current elevation is also 0.79 feet (9.48 in.) lower than it was at this time one year ago.
7-2-18 As per Lassen County, 5095.68ft.  2.52″ lower in one month.
6-30-18: 5095.71ft.  About 5095ft 8 9/16″  A little over 2″ lower in 22 days.  About where we were 8-6-17.  Not bad considering.  But now we will likely see an uptick in evaporation as July/August are generally our highest evap months.  Light wind at the time.  Not official (measured at the benchmarks at Spalding ramp and could slightly change as wind was slightly pushing water in from the northeast at the time. 
6-8-18: “5095.89ft” (About 5095ft 10 2/3″) as per Lassen County official measurement.  8.5” lower than last year at the same time. Basically about where we were in late July 2017.
6-2-18: 5096.08ft or 5096ft 1″.  About where we were on 7-15-17. Still a bit higher from the rains before opening weekend.  But it’s going to start evaporating faster now.
5-20-18:  5096.06ft. 5096ft 11/16″ Holding thanks to some passing showers, cooler temps adding to less evaporation.  Light easterly breeze 0-2mph at 8:15AM.  On 5-2017 the lake elevation peaked at 5096.7ft.  Still around 7+” below last years elevation.
5-13-18: 5096.05ft.  Or 5096ft 9/16 inch.  Down around 1″.
5-1-18: Lassen County measurement 5096.12  (Peak elevation of 5096.7ft in 2017 was on May 20th)
4-28-18: 5096.15 or Approximately 5096ft 1 17/32″ (just a hair over the 1/2″ mark. Down about 3/4″ in 8 days which is pretty close to normal evaporation for this time of year considering the heat and winds last week.  Now just hope we see some more weather come in to help. A good local thunderstorm could help bring us back up a smidge.
4-21-18: 5096.18ft or Approximately 5096ft 2 1/4″ (a fraction of an inch below the 1/4″ mark.  Probably about where we are going to peak this year unless we see more local storms.  Pine Creek not at a rate to keep up with evaporation at this point.  
4-13-18:  5096.15 or Approximately 5096ft 1 1/2″ up about 1/4″ in 4 days after 0.30″ of moisture.
4-9-18:  5096.104FT.  Approximately 5096ft 1 1/4″ which is up 1 3/4″ from 3-27.
3-27-18:  5095.96FT or 5095ft 11 1/2″  up around 1 1/4″ since 3-22 (about where we were in late July 2017)
3-22-18:  5095.82ft or 5095ft 10 1/4 inches! The lake came up around 2 1/4″ in the last two days of the storm event which dropped 3.85″ of moisture in 48 hours!! WooHoo!  Unofficial but measured using intelligence, stationary markers and a real measuring stick. LoL.
3-20-18: 5095.66ft or approximately 5095ft 8″. Unofficial measurement at the Spalding ramp and there was a light wind blowing at the time.  So we are up around 4 inches since mid January.  Better than being down from January. LoL About 1 ft to go to reach 2017 high level of 5096.7ft
1-16-18: 5095.38: approximately 5095ft 4 inches.  Unofficial measurement, but a starting place for 2018.
 
2017 LAKE ELEVATION
 
9-24-17 5095.26ft, losing .6in per week.  1.47ft lower than it’s highest elevation as per Doc Bateson.
9-4-17: 5095.41ft and lost .94″ since 8-6-17
8-6-17: EAGLE LAKE is dropping at a rate of 1.425″ per week since July 2nd. It is now at 5095.73′ and has lost 7 & 1/8″ during that time (about a month).
7-15-17: As per Doc’s measurement the lake elevation is 5096.07ft; 7/8″ above 5096ft.  It has dropped 3 inches in two weeks and up to 1 1/2″ per week evaporation.  This is actually normal evap for this time of year.  Going to be a long summer.
7-2-17: As per Doc’s measurement the lake elevation is 5096.32ft and it is dropping 1.33 inches per week.
6-23-17: As per Doc Bateson the lake elevation is 5096.479ft.  It has lost 2.65″ since May 20.  Now that Pine Creek and other tributaries are no longer flowing into the lake we will begin to see our evaporation pick up a bit.
6-2-17:  As per Doc Bateson our lake elevation perfectionist; 5096ft 7 and 5/8ths inches. That’s 5096.635’ it  has dropped .065’ or  .78” (a little over 3/4″) in 13 days.  
5-20-17:  As per Doc Bateson the lake elevation measured 5096.7ft
4-30-17  As per Doc Bateson’s measurement ” 5096.375′ which is 5.515′ higher than on December 3rd 2016. It has risen 1.427′ Just since March 18th.
4-18-17 Unofficial measurement at the Spalding ramp was 5096.54ft.  Winds were blowing lightly so the elevation could be slightly off.  Creeks are slowing down some now so we are probably going to see a slow down of rising.  Any storm passing through can have flow pick up. 
4-3-17 Lassen County Official Measurement: “We made our monthly visit to Eagle Lake this morning and found that the lake has come up 1.38 feet over the past month.  The elevation at the Gallatin Ramp is currently 5095.78 feet above sea level and the lake has come up 4.99 feet since November 1st of last year.  It is also 3.22 feet higher than this same time one year ago. 
3-29-17:  5095.64′ Measured from the elevation tags at Spalding ramp.  A gain of about 2inches in 4 days. Flows in Pine Creek subsiding a little this week from last week, so we expect to see a little slower rise unless a storm passes through.
3-25-17: 5095.45ft (unofficial) Measured between the elevation plate screws at the ramp in Spalding. A gain of around 6″ from the increased flow of Pine Creek and just over an inch of rain on 3-21.
3-19-17: 5094.948 as per Doc Bateson.  Up a couple inches in the last few days.  We have about 5/8′ to resach 5095ft.  Up a little over 4ft from our lowest water level last year and about 2 1/5ft above last years highest level.  So we are doing ok, but could sure use a lot more.
3-16-17: 5094.8′ up around 3 1/2 inches according to the markers at the Spalding ramp.
3-8-17: 5094.5ft according to the markers set by Doc Bateson at the Spalding ramp.  Up around a foot in the last month.
2-12-17 5093.4ft
2-11-17: 5093.38FT As per Doc Bateson.  2.52ft higher than Dec 3, 2016 (which had held due to Oct/Nov rains). 18.29″ of moisture since July 1 here at the house in Spalding.  So the springs were still pumping good over winter too.
 
2016 LAKE ELEVATION
 
12-3-16:  5090.86ft As per Doc Bateson.  Still a few inches above last year, but still below the record.
10-20-16: 5090.866′  (after 3.03″ of rain)  Without the recent rain, the lake would have been where it was last year.  So we didn’t keep the 6″ of water we had over last year.  Only the rains brought it up.  Bly Tunnel from the valve remains dry.
7-3-16: 5092.23; almost 6″ lower than 5-30, but around 6″ higher than last year at the same time.  As per Doc Bateson.
5-30-16 5092.72: as per Doc Bateson, up 1/4 inch since 5-1.
5-1-16 5092.7FT  Officially as per Doc Bateson, the lake is only 5.76 inches above last year’s elevation, May 2, 2015.  Expect similar conditions to last season.  We still have 27 days to go.  Hopefully we see more showers and hold on to that 5+ bonus inches to help get us through the season launching!
3-19-16 5092.43FT.  UP 1.835FT SINCE 11-22-15.  2.52 INCHES HIGHER THAN MAY 2 2015.  As per Doc Bateson’s report

8-30-15:  5090.97ft 
8-16-15: 5091.2ft as per Doc Bateson’s measurements.  We lost 2 1/2 inches in 2 weeks and are only 2.4 inches away from our lowest recorded level in 1935.
8-1-15:5091.4ft as per Doc Bateson’s measurements.  We had 2.41 inches of rain in my backyard in July  (2.68″ at Spalding’s sewer ponds 2 miles NW) and the south end had more than we did up north but it helped counter evaporation.
7-4-15:  5091.70ft as per doc Bateson.
6-20-15: 5091.83ft;  now just 9.96 inches from our lowest recorded level in 1935.  (lost approx 4″ in the last 20 days.

September 2, 2013 5093.9ft; 18.5  inches lower than April 28.
July 28, 2013 5094.44 ft, about 5094 ft 5 inches.
July 7, 2013 appears to be about 2-3 inches below 5095ft…. or 5094ft 9-10 inches or so.  Unofficial.  Going by the end of the cement at Spalding ramp being out of the water & taking chances that the end of the cement is at 5095ft elevation.
June 1, 2013 was around 5095ft 1 inch.  About 6″ of cement in the water at Spalding ramp. 
4-28-13 5095.44ft
4-11-13 5095.5 ft (unofficial by the markers at Spalding ramp)….I guess my estimate was only 3/4 of an inch off.  Not bad for a girl ehe?
 
2012 LAKE ELEVATION
 
4-2-12:  5096.42 ft or 5096 ft 5 inches. 
Ending Nov 2012 5093.70
 
2011 LAKE ELEVATION
 
MARCH 10, 2011 – 5096.28 UP 0.68ft up around 8″ from local winter moisture, measurement taken hours before Pine Creek flow reached the Slough.
MARCH 17, 2011 – 5096.50, UP 2 1/2 INCHES IN ONE WEEK OF FLOW
MARCH 26, 2011 – 5096.63 FT; UP 2 5/8 INCHES SINCE 3-17

APRIL 24, 2011 LAKE ABOVE 5097 FT! @ 5097.168 (almost but not quite a seven) UP A LITTLE OVER 2 INCHES IN 5 DAYS! INCLUDING A LITTLE OVER ½ INCH OF LOCAL MOISTURE SINCE FRIDAY MORNING! UP 10 ¾ INCHES SINCE PINE CREEK BEGAN FLOWING!
APRIL 27, 2011 – 5097.28FT! or 5097 ft 3 3/8 inches.
MAY 1, 2011 5097.34 FT or 5097 ft 4 1/16 inches; up 5/8 inches

MAY 16, 2011 – 5097.44 FT.  NO CHANGE IN LAKE ELEVATION FROM 5-7-11.  One and a quarter inches more water than last year means it is still going to be a bad year for the lake level.
MAY 21, 2011 – 5097.49 FT up 5/8 inches since May 16.  Coincides very closely to the amount of local moisture in the last 5 days.  Due to heavy winds that haven’t stopped long enough to get an accurate elevation we have not taken one.  However, we can tell you that we are still pretty much the same and still well below the 5098 ft elevation.
MAY 30. 2011 – 5097.59, up around 5/8 inch in 9 days.  Again, coinciding with the amount of local precipitation.  We aren’t gaining and we aren’t losing at the current flow rate of Pine Creek.  We have now just officially reached the 2 ft mark since the lowest lake elevation in Nov 2010.
JUNE  12, 2011 – 5097.68 ft from 5097.59 ft on May 30.  Increase of around 1 inch (for elevation in inches it is 5097 ft 6 7/8 inches).  We also had over an inch of precipitation fall in the basin in the last 10 days.
JUNE 24, 2011 – 5097.57 ft from 5097.68 ft June 12.  That translates into inches as down nearly 1 3/8 inches in 12 days.
