Document Description
In November of 2011, during a diving inspection Yuba County Water Agency (YCWA) discovered two small areas of scour on the toe of the Log Cabin Diversion Dam spill apron on the downstream side of the dam. YCWA plans to repair the scour areas by drilling dowels into the existing concrete and stream bed in the scour area and then filling the scour areas with fiber reinforced shotcrete which contains a high silica fume content. A discharge pipe from the upstream Log Cabin Diversion Dam temporary impoundment will be extended approximately 150 feet downstream of the dam to allow an estimated 8 cubic feet per second of streamflow to pass around the construction area. A combination of sandbag barriers upstream of the discharge pipe and sump pumps will dewater the construction area, allowing the work to proceed in dry conditions.
