Teh Ohio tribs are probably in decent shape if you don't want to go as far as polaski.
when I drove over the chagrin last night, it looked pretty good to me. A little low, but decent flow, and this was way south near Gates Mills. Grand is probably about the best it could get. Normally pretty cloudy. Conneaut creek? I don't know. Probably low, but you could hit it on the PA side. it drains a large area so might have enough flow. I'm betting there are fish that far easy.
Ohio's runs are usually better in the spring, but Conneaut Creek is stocked by PA.
