When it is full, it covers about 5 square miles. Rainbow trout are also stocked here. Worms are the bait of choice of anglers who fish from the bank and from boats. Prineville Reservoir is about 12 miles southeast of Prineville. Walton Lake Hidden away in the Ochoco National Forest about 25 miles northeast of Prineville, this lake is stocked with rainbow trout that average 8 to 10 inches long, although you may sometimes catch a nice 16-incher.
Anglers here use flies, bait and lures, and the lake is small enough to easily fish from the bank.
There are two Forest Service campgrounds, which can be quite busy during summer weekends. Boats with gas powered motors are not allowed. You can reach Walton Lake by driving east from Prineville on U.S. 26 to County Road 23, then following Forest Service Road 22 to the campgrounds.
