I would think you could launch at Alma with the nice steep ramp, but I have not personally been there to verify. Their dock may be pulled, but that’s not really a big deal.
We caught some eater-sized fish and one 4-5#er a couple of weeks ago when out for a few hours. It wasn’t overly fast but there were some to cooperate. A lot has changed since then, but we were a good 1/2 mile from the dam and looking for bigger fish. The level was a couple of feet lower. Use extreme caution if you go out.
Stay away from the scour hole that so many anglers tend to crowd into. In my experience these are mostly tiny fish and pulling 10″ saugers from 30′ of water is just making eagle food. For some reason the anglers below the Alma dam have struggled to grasp this concept for as long as I’ve fished the area.
