Green River Help needed for trip

I am looking at taking my old man down for a little trip to Green River. We have never been there and I am trying to decide between late March or early April but will wait for good conditions. I see the water level is currently at 692 with summer pool being 675. Should I try to avoid anything over summer pool? Any advice appreciated. I long line troll mostly but will cast if fish are on the banks.

Suggest continue to chk water level, best at or near summer pool.

I have caught them at green when its 10 or 12 feet over summer pool. Right now the lake is muddy and most boat ramps are closed. I feel like if as long as I can get my boat in I can catch them.
