I read about that Limnic eruption and it did not sound like one of those, seeing how as there have been only a few ever recorded.

Speculating on what others have posted, a lake with little aeration (no stream feed), high algae growth (as in nastiness), combined with an extreme cold spell in the last month, it sounds like it might have been a "violent turnover" as the article suggested. I'm still learning about the whole process, but as suggested above, many (or all?) lake type bodies of water do some sort of mixing in the winter months. It sounds like a very deep body of water in a rather small area. It will be interesting to see what the scientists have to say about this event.

Any more news on possible causes?

Ron: Re your comment!
If there were contaminants 300 feet down and a "violent" turnover happens~~~???

I suppose the fish did fine with the bodies in the pond with concrete-overshoes?

Sound like a good place to drop off those that pissed off the mob

One thing of note is that it was extremely cold (record setting)for several weeks a couple of weeks before this event. The marina had frozen over for a short time, which I can't remember happening before. The fish die off was at least a few weeks after this though.
Saw something in the news about a theory that some kind of "water turnover" from the bottom of the lake, which has less oxygen?, may have been caused by the freezing. Did not read it closely and it did not sound definitive though. A shame about the fish, I've seen some HUGE fish, swimming near the surface, in there.
I was there two days after the fish die off. Not a dead fish to be seen anywhere. The water was clear with good visibility and really no algae. (It has a popular swimming beach in the summer for the kids)

Also..the pit had not been active for awhile when it was flooded. There had been lots of discussion on what to do with this MAJOR eyesore in the middle of Sparks and how to reclaim it. (As well as concerns that there might be contaminants in the ground at the site....then walla....the big flood which caused the Truckee to overflow it's banks and fill the old quarry site.... and presto...The Sparks Marina was created "overnight", without a bunch of long, drawn out governmental red tape to figure out what to do with the place.

SPARKS, Nev. (AP) - Another round of tests confirmed there's no toxins in the Sparks Marina and its oxygen supply is slowing rising after a sudden drop in oxygen levels choked off the man-made lake's entire fishery.

The massive fish die-off in December claimed an estimated 100,000 trout, catfish and bass at the former gravel pit along U.S. Interstate 80 just east of Reno.

Nevada Department of Wildlife biologist Chris Crookshanks tells the Reno Gazette-Journal new tests found nothing unusual beyond the lack of dissolved oxygen.

Scientists believe a week of unusually cold weather caused a sudden turnover of the 77-acre marina, sending the warmer, oxygen-rich waters from the surface to the lake's bottom.

They're optimistic the oxygen content is recovering and more fish can be restocked there in the coming months.

^^^^^^^It will take years to get breeding fish like they had back in there..
