Document Description
Hell Hole Dam is part of the PCWA's Middle Fork American River project (FERC Project No. 2079). PCWA proposes to raise the impermeable core of Hell Hole Dam to ensure that seepage that could occur above the dam core under probable max flood loading is safely controlled, consistent with DSOD and FERC dam safety requirements.
