VIDEOS SHOWING THE LAKE RISE 2017
South Basin 7-25-17: Surface temps started out around 72-73F. Rising to 74+ by 10am. The 63-64F surface temps have pushed south and west the last two days...making it's gyre up the west side this week. Thermolclines nearly non existent. Barely 9F difference between the surface temp and 45ft. My recording temp gaget indicates it is 73F+ to 15ft, 71F @ 20ft, 68F at 30ft, 69F@ 35ft and 64F at 40-45ft deep. But, just because it is cooler water at 40ft deep and below, doesn't mean the dissolved oxygen is desirable for trout. The trout have come up the water column for me, most every trout has been 17 to 23ft deep, which tells me the dissolved 02 isn't adequate for the trout for very long below that level. DFW has NOT conducted any water tests this summer. We hope to have some soon, but it's pretty obvious what is going on....same thing happened last year. That green cloud that starts around 17ft and lower appears to be taking it's toll again. So get your lines up into the trout zone. Lot's of chubs scattered in the water column right now.
The springs are holding temps down to 59-61Fbut on average at 63-64F. The clarity is getting a bit worse and I couldn't determine bottom at 6-7ft in several places. We are seeing more of a green hue and as per underwater video, a green cloud pops up around 17ft.
The surface was pretty clean today on the east side but quite a few scattered weeds in the middle and on the west side. Mostly worse out in the middle of the south basin, but we have found a few thin tules floating on the surface in several locations. Good idea to check lines periodically. Much weedier further north.
We have baby grebes on the lake now, a first since 2012. Please note that the mothers don't dive with babies on their backs. Be careful speeding along in your boat early in the morning. The female will simply flare her chest and take the brunt force of the boat hitting her if she can't get away in time. Without her the babies will die anyway so it's critical that she survives. Once the babies are swimming by themselves and learning to dive the chance decreases of causing them harm. This goes on for several weeks, basically until the young start sporting their adult plumage. Dad's do most all the feeding, including the female. So his life is critical too. The male Clarke's seem more aggressive and literally "chased" my boat when trolling. LoL. He wasn't too happy with my presence.
Spalding: 7-25-17 Water temps starting at 74F & 76 to 77F+ by afternoon. Tui chub spawners moving back into the depths all week and we are seeing an influx of big chubs in the south basin. Pelicans are having a pretty good time along highway 139 so we still have some hope for trout to show up in fall. Hold on.
Depth between Spalding ramp and Rocky Pt still doable. Gets deeper the further south you go to the channel at the Youth Camp. Was a bit weedy on the surface and we had an increase of algae here and there on the south side of Pelican Pt. Grebes are everywhere, including the south side of Pelican Pt and the north basins.
Just because we got a little water in the lake this year, doesn't mean we don't still have dangerous rock piles to be aware of. So be careful out there. The trout are a long way away right now. In their summer haunts & over the depths and about a 5 gallon round trip back and forth in a boat. I can burn 5 gallons of boat gas getting down there from Spalding, 2 gallons round trip to tow my boat down there and launch for free and quarts in my boat. Until we get more water and I am spending more time fishing up north, I'll be launching down south where the best fishing is. Give me another 9ft of water & I will be spending all but about 3 weeks of the season fishing above pelican pt and will most likely be launching in Spalding. Until then, I will be launching at the south end and saving fuel and money.
Yearly, during the fishing season we will lose over 2ft of water by late Oct. Already loosing water to evaporation at 1 1/2 inches per week. We will see this evaporation through summer before it tapers back down to around 1" per week in Sept. Depending on the winds, August can see an uptick of evaporation.
I HAVE MET WITH TU REGARDING SOME ISSUES IN THE DRAFT PLAN THAT DIDN'T FIT IN WITH SAID RESTORATION. We will know more after CRMP meeting and field trip on May 31. Meet at Bogard Rest Area at 9am, bring bug spray and boots for mud & muck to walk at restoration area.
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. IT ENDS A VERY GOOD DISTANCE FROM ANY ACCESS TO THE WATER. Walk on the vegetation. There are several trails. A statement from LNF has been long requested and short on delivery. This is a very dangerous "trail" to the lake. I have been hounding USFS to get the access repaired. I was told this week that LNF is still waiting for the State Lands Commission for input and approval to repair the existing handicap access.
2017 LAKE ELEVATION
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 measurment " 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.
3-8-175094.5ft according to the markers set by Doc Bateson at the Spalding ramp. Up around a foot in the last month.
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 ovre 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
2015 Eagle Lake Elevation
10-18-15: 5090.61 and holding
9-30-15 5090.6 ft
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.
6-1-15: 5092.16ft now just over a foot from lowest recorded level in 1935
5-2-15: 5092.22ft as per Doc Bateson. About 1 ft 3 inches above lowest recordered level in 1935.
2014 Eagle Lake Elevation:
9-15-14 5092.035ft. As per doc Bateson, our local doctor and scientist we are now about 1 ft above the lowest recorded lake elevation of 5091 in 1935. Note: "recorded level".
2013 Eagle Lake Elevation:
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.
4-11-13 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 Eagle Lake Elevation
4-2-12: 5096.42 ft or 5096 ft 5 inches.
Ending Nov 2012 5093.70
LAKE ELEVATION FOR 2011
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
MARCH 29, 2011 - 5096.66 FT

APRIL 14, 2011 – 5096.90 ft
APRIL 19, 2011 – 5096.98 ft. Up 0.08 ft in 5 days…or around 1 inch.
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 7, 2011 – 5097.44 FT Or 5097 ft 5 ¼ 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.
JULY 5, 2011 – 5097.46 from 5097.57 on June 24. That translates to 5097 ft 5 ½ inches. Down 1 ¼ inches in 10 days. Average daily humidity as been 13%.
JULY 18, 2011 – 5097.23 Ft from 5097.46 ft on July 5th. Down around 1 3/8 inches in 13 days which levels out at 5097 ft 2 ¾ inches.
JULY 24, 2011 – 5097.15 FT from 5097.23 ft on July 18. Down 3.96 inches since July 4 as per Doc Bateson.
AUGUST 4, 2011 – 5097 ft from 5097.15 ft on July 24. About 1 ¾ inch drop in elevation.
AUGUST 8, 2011 – 5096.97 FT from 5097.0 4 days ago

AUGUST 24, 2011 – 5096.68 FT. Down from 5096.86 ft 12 days ago.
AUGUST 30, 2011 – 5096.56 FT. Down around 1 ½ inches in last 6 days
SEPTEMBER 6, 2011 – 5096.45FT, Down around 1 3/8 inches in the last 7 days.
SEPTEMBER 20, 2011 – 5096.34 FT. Or 5096ft 4 1/8 inches.
OCTOBER 14-11 5096.18 or 5096 ft 2 1/8 inches
LAKE ELEVATION FOR 2010:
