Reds will stage around run-offs and marsh drains, etc. just like Bass- If the water gets too muddy, then they will leave. Crawaddict is correct, Specks dont like freshwater. Flounder can be found feeding also, not much effect on those. There are times when the Tides come in or out for a few days after a good rain,there will be a layer of Saltwater on the bottom. The Freshwater will be on top- Salt is denser than Fresh.I've fished the Bayou many times with these conditions...Caught Bass on the Top of the water column, Flounder, Reds, Blue and Channel Cats, and of course some Specks -NOT all at once, just over the years...
