When you get to the bottom of the hill make a 90 degree turn left.  Follow a small game trail running parallel to the steep hill for about 20 yds then look for a path off to the right which leads to the lake .

2 We found all the south end of the lake camp sights burned.  We found a nice but small campsite on one of the first islands we came to.  We found lots of garbage at the sight and there was a group on another sight that had several tents,  2 huge tarps up and were most likely base camping.
