Any trout coming out of DVL?

The last trout plant last week most of the fished didn't make it. Saw a picture of them on Facebook all on the bottom of the lake by the marina.

DVL is strictly a put and take trout fishery anymore (like most lakes in SoCal). Severe lake stratification and anoxia in the colder hypolimnion throughout most of the year is prohibitive to holdovers. The lake started to turn over dropping the dissolved oxygen to about 4 ppm when the marina planted last week which likely led to the mortality.

the short answer is--the lake evolved into a eutrophic waterbody that exhibits higher productivity, rich in algae with considerable fluctuations in surface and benthic oxygen levels typical of shallow water in a lake basin that is more typical of oligotrophic lakes. Oligotrophic lakes are unproductive, deep with very clear water that are fully saturated with dissolved oxygen. DVL might have been relatively oligotrophic early on, but absolutely is not oligotrophic in water chemistry anymore.
