right now the fish are starting to school together, staging up by the rivers and r waiting for the cooler waters, over then next few weeks the fishing will pick up. by the middle of August it will be almost at the peak, hens will be looking to fill up on bait fish before spawning as will the males. come September they are going to be ready to enter the mouths of the rivers if water levels are up and cold they will be in the rivers mid sept.
if you plan a boat trip out on the lake the next 4-5 week will be good fishing, after that it all depends on the weather, rivers and temps.
