Yeah, I used to fish Gervais all the time. The spot I would catch the eyeballs was on that point that extended out into the middle of the lake (if you need a map, see http://www.fishnbudz.com) and fish the eyeballs in 20+ feet of water.
The action that is highly, highly under-rated on Gervais is the carp action. Go out there with some stink-bait on a hot, summer afternoon with a six-pack and some slip-bobber rigs. There are 40 pound+ carp swimming these waters.
Frankly, the carp are muscling out the other fish, so catch and smoke some of them!
