well over 100k fish. Started in dec and then yesterday the whole lake went belly up. Catfish, small mouth, spotted and striped bass, sunfish, and trout. They ran fish finders and no fish can be found alive in the lake.

The lake is over 300 feet deep- an old construction pit that flooded in the 97 floods and filled to the brim.

They think a "violent" turnover may be the culprit for low oxegen levels that killed every fish in it. UN REAL!!!!!!

Massive fish die offs are a regular occurrence in the Salton Sea, although they don't all die.

Stinks up much of So Cal when it does happen.

The Salton Sea was also created by an industrial accident.

Sorry to hear of this die-off. Not any fresh water oxygenating these small lakes. Bummer.

They say there is an underground aqua-fir feeding it, the levels rarely change at all. Im wondering what EXACLTY was at the bottom of the material pit when it flooded.. Thee is one in BM that flooded with an office and many heavy machines etc in the bottom 100 feet down.

If it was a turn over, then there should be visible signs on the surface, which dont seem to be there. ie algae and other forms of aquatic mass.

They lost some very nice fish- a rare thing for the city and area enjoyed by many.. Thats the most rapid die off ive ever heard of here.

The seagulls at the lockwood land fill are gonna party for a long time to come.

Ron, an underground aquifer might not provide oxygen... no turbulence. Second thought ground fed. Hmm

Well its been working since 1998 when they first planted fish there. SO it has to be fed from something substantial enough to have oxygenated the lake for some time. I know the maj of fish were in shallow locations 30 feet on up in the lake- as that seemed to be the deep thermocline according to my graph recorder..

But under ground seems worriesome for sure. I cant remember of the pit was active at the time of the flood, but i think it was.

If there were contaminants 300 feet down and a "violent" turnover happens~~~???

Toxins perhaps. Bummer.

They have only measured the oxygen from what i gather - in the n shallows where the fish die off is prevalent. Im sure they will sample for other things i would think. There were 16 yr fish in there.. The bass/catfish all reproducing fine. Trout were continually stocked.

Fishing opportunity are rare for many nevadans.. It just got more rare.

Don't most lakes turn over in Oct-Nov?

Indeed they can. Some to different levels. Different times of the year as well. They are talking about a "violent" one..?? I dont know if they mean TIME wise or what. Never heard that one before.

Most calendars turn over every month.


Rong, I don't know EXACLTY was at the bottom here, but I don't think it could be the INSETCS the fish were eating.

Wow Ron, I read the article that sounds rough, 100,000 fish possibly wiped out. The article hinted at possible contamination from some sort of underground oil storage facility.

Some additional information scammed off wikipedia:

"Natural resource and environmental managers are often challenged by problems caused by lake and pond thermal stratification.[4][5][6] Fish die-offs have been directly associated with thermal gradients, stagnation, and ice cover.[7] Excessive growth of plankton may limit the recreational use of lakes and the commercial use of lake water. With severe thermal stratification in a lake, the quality of drinking water also can be adversely affected.[8]

For fisheries managers, the spatial distribution of fish within a lake is often adversely affected by thermal stratification and in some cases may indirectly cause large die-offs of recreationally important fish.[9] One commonly used tool to reduce the severity of these lake management problems is to eliminate or lesson thermal stratification through aeration.[10] Many types of aeration equipment have been used to thermally destratify lakes. Aeration has met with some success, although it has rarely proved to be a panacea.[11]"

Edit: Interesting Johnyrig, I went back and highlighted a sentence above in regards to "nastiness"

its speculation until they get evidence. last time i was there it seemed kinda nasty to me, with lots of algae as Ron said above. dont believe it was active at time of flood.

global warming.

Ok,, IRONY ALERT !!:



from the article Albert posted:



Routine toxicity testing of the marina water has revealed no problems, said Michael Drinkwater, manager of the Truckee Meadows Wastewater Reclamation Facility








Hi,, im Drinkwater from the waste water facility LMAO!!!!

These are always interesting.

If the water is relatively contaminant free, it's almost certainly an oxygen levels issue.

I'd be looking at temperature data as a starting point, hopefully with monthly or more frequent data over at least the prior 5-10 years.

Warm winter, less than normal winds, anamalous turnover...many things could be contributing to low DO levels. The rainbows tends to fare a little better than most trout/salmonid species in lower DO/higher temp waters, and bass and panfish are substantially more tolerant than the rainbows. So I'd expect to see the dieoff somewhat segregated by species over time, unless it was an acute event that happened in a very short period.

Will be curious to see what the ultimate report says.

Is that a gated community?

Is that a natural lake?

So, the toxins in the landfill that this gated community is built on has finally broke the blood brain barrier and started to kill, starting with the fish.

Nothing to worry about. Certainly no cause for alarm.

Cheers all

Everyone knows about lake/pond aeration systems.
Tens of thousands of them are operating around the US right now.

edit: Well obviously not in Sparks but everyone else knows.

Any chance it was one of these?

Seems like a scary phenomenon - especially when the CO2 impacts the surrounding terrestrial biota.
