Continue on Centerville Rd. It soon turns to dirt but is relatively well maintained. Continue for 6.4 miles. Turn left onto cement at the Y with Nimshew Rd. In 0.5 miles turn left again on Humbug Rd. In 1.5 miles, turn left on the first road “De Sabla Powerhouse Rd.” It sneaks up on you, within 100 yards you should see PG&E signs letting you know you are on the right path. Drive another 1.5 miles and park at the gate. If the gate is open, I would discourage you from driving down as that is a great way to get locked in. Once you see the powerhouse, look for a road on your left that drops steeply down to and crosses the canal. Work back upriver to drop the final 20 feet down to the water. (Credit: A Wet State)
