We stayed at Big Rock Campground, which is nicely wooded. We saw moose each day we camped there, so I'd recommend that CG for wildlife viewing. It's a 10 min walk to the lake, so if you'd rather be closer to the water look at Moraine or Roaring Fork CG. Only gripe is that people speed along the road that connects them all, so find a site on one of the loops.

Running water available in all loops.

This is a great campground with sites featuring full hookup as well as electric only (down by the reservoir). I was most impressed by the fact they all have a fire pit with cooking grate in addition to an upright BBQ with picnic table. Sites that don't seems to have that much shade have a pavilion covering the picnic table.

If you camp here you also get access to their sister park (Red Fleet), which has more scenic waters.
