When I was out fishing last weekend we had the same discussion. I believe Kingfisher mentioned there is a back oil lease road that goes right into there. Shoot him a pm he probably can add more to the story.
if you drive past the entry way just around the bend a bit, the next left there is a trail that takes you down to the lake, i would only take a 4x4 truck down the trail because of the snow, but otherwise its a excellent trail.
