Excavation and Stabilization of the Accumulated Sediment

Although the majority of accumulated sediment was already on the Carmel River side of the reservoir, approximately 380,000 cubic yards of sediment that had accumulated in the San Clemente Creek arm had to be excavated and added to the Carmel River sediment storage area. Sediment that had accumulated immediately behind the dam on the Carmel River side also had to be excavated and moved further upstream. Once all the sediment excavation and placement was complete, the sediment slope was stabilized to ensure that it will not be eroded by the river during high flows. The sediment stockpile area was landscaped to mimic the upland scrub habitat found on the surrounding hillsides.
