Document Description
The project will manage the water level behind the historic Jack London dam prior to winter storm events in an effort to prevent dam failure. The existing condition of the dam face consists of multiple leaks. Water level will be managed through a constructed concrete intake structure with overflow weir which will set water levels 5 feet below the top of the dam. An outflow pipe will be installed from the intake to the natural ravine just below the dam site and a turning structure will be installed to enable the discharge pipe to make the sharp turn to the east beyond the edge of the dam. The outlet of the outflow pipe will be armored with rock to dissipate outflow prior to being conveyed to the creek. An existing gate valve will be removed. The inlet structure and turning structure will be faced with rock similar to the existing historic dam rock. A temporary working pad will be placed at the edge of the lake. All rock work in the existing overflow channel will be retained. All existing features associated with the dam will be preserved in place.
