I was up at the dam this morning, and was going to come home and post a question about this, I have lived my whole life near this river (48 years) and for the past few years it would get cloudy in the fall for a while, seems the generation would straighten it back out, now it has been cloudy all year, even with it generating this morning I couldn'd see maybe 2 feet deep.
Any water scientist on the board

I figure maybe all the gazillion homes that have been built around the shore, some say its the sewage discharge from Winchester
