Killer - When I was there the head of slackwater was about 8 or 10 miles above Leslie Gulch. If you look at a map, the mudflat began just above where the lake bends to the west. Atlas of Oregon Lakes says the lake is 117' deep at the dam and averages 83' deep with 4% shoalwater (at full pool). There are no channel markers that I recall except near the launch - just stay away from the sharp ridges that come down on the inside of bends. I doubt if there are any underwater peaks very far offshore at any lake level since it is a dammed river canyon. And, yes, camping along the shore is doable but it is totally unimproved, dry, dusty. The water was covered with thick algae bloom when I saw it. You will find thickets of burr bushes growing in the exposed parts of the drawndown lakeshore. I would guess you'ld need to get there a day or two early if you wanted to camp in one of the relatively few decent spots other than the campground - but those are also probably the best bets for deer? Take your hiking boots, canteen & snakebite kit - its rough country.
