I was there in a boat too. I was using the alwives and threads coming out of the dam and bumping them on bottom. I only had one bite all morning and then left at noon. There were at least a dozen other boats there and I never saw a single fish come over the side of the boat. Went to the lake to try and salvage the day and it was a ghost town in the head of Indian too. Never saw the first bait flip or swirl. I bottom fished the dead bait I had and never got a bite on the lake either. Oh well, it was a nice day.
