The lake is 475 acres if I remember correctly. The boat ramp is decent and only one lane. If the water gets really low it's unusable. The lake has a no wake rule, but i don't know if buying a permit excludes you from that rule. The lake is fairly deep all over and only standing timber is in the Hell Creek arm near the dam. The lake used to have black crappie in it, but it was pretty rare to catch one of those.
Fished the lake a lot from a canoe, a old jon boat, or my dads old boat, all of which had no depth finder or very old technology. So fishing brushpiles was based on lining up with certain trees and a certain depth. (wait, I still do that today even with better depthfinders and gps). haha. Fun times...
