Re: Not fishing at this lake for a while.....
Yup it is from phosphate run-off and happens in Lake Champlain in areas too.
I agree with the phosphates.
My dad and I did the underground and plumbing on both sides of the Lake in 1975. We didn't do the sewage pump that squirts the poop across the bottom of the lake in a 12" pipe and up and over the hill to the main city sewer line. Guess where I'm thinking those phospates are comming from.
P.S. Looks like Clear Lake before the Sewage Reclamation plant went in.
P.S.S. The Park is state (Ca), Let's see what Jerry (Moon Unit) does with this.
