Anyone have luck fishing in the Sudbury, Assabet, or Concord rivers this year?

Just got off the Sudbury River. One bass 1.5 lbs in 4 hours. Had several swipes at a frog. That's it. Talked to every boat on the river and nobody had more than one fish. Water was 83 degrees and air temp was 93 and it was mostly sunny. Very slow. The water was very stained. I tried a lot of different techniques and locations. They just weren't biting. I have done well at times here, but when it's hot and sunny, I have not caught many fish.
