One thing to consider concerning the littoral zone and productivity in these reservoirs is that there is a large Mysis shrimp population. Once the juvenile Bulls and rainbows migrate to the Lower lake from the creek, their growth rate rapidly increases. I believe the juvs are about 6" at 3 years of age and then they start rapidly growing in the lake. Stomach contents that I saw from Bull trout in the Lower lake were almost totally shrimp. Once the fish get bigger they can add sucker minnows to their diet.
There has been a request to stabilize water levels for a long time. I'm not sure it is a priority for the power company. A stable littoral zone would surely help, but the Mysis shrimp add a ton of fat/protein to the equation.
