I know you can come in from Parshall and follow the road around the lake until you get to the south west side. As you head towards the dam you do run into a locked gate like Co.Trout said. There are a couple of places there you can get down to the lake, but they are a little bit steep. A heavy sled makes for a real workout getting out of there. Your still about a mile from the dam though. I have caught a few small lakers there but I don't know if its worth the climb.
