Musky in SF lakes

She looks like she's eaten more than a few of them....

I have spent a fair amount of time working on and around the dam at Pilarcitos lake. (We run the gage height record for this lake) I have been there in the late afternoon when the surface really came to life with rising fish.  I am not sure what species they are, but Ive always assumed some sort of trout. It can be very difficult to concentrate on work when a hot surface bite ensues on a water you are forbidden from fishing.       Such is life...
