San Joaquin - 4. Patterson Bend (Kerckhoff Reservoir to Kerchoff #1 PH) (CA)
Approximate - nearest available gauge. Use as general reference only.
Big rapids start around this point. The second one is junky at lower flows and will be a portage for many boaters. The rapid has several steep drops with some constrictions in the first or second drop. There is a low water portage route against the right wall that probably also serves as a high flow sneak route.
