I would think you would be safe from all the recreational users anywhere in April, its still pretty cool that time of year. I would think it would deoend on how large an impoundment you are looking for. Most all of the Corp lakes here are away from population centers and offer excellent camping accomadations.Check out Lake Greeson, thats where Jerry and Darryl guide out of and they are always catching fish it seems.Hope this helps.
