Pickerel Floodplain Restoration

Pickerel Floodplain Restoration

The purpose of the Pickerel Project is to restore functional floodplain elevation to the north bank of Putah Creek for 800 feet downstream of Putah Diversion Dam. This area was heavily infested with arundo prior to 2002 when control operations began. For decades arundo obstructed flow causing sediment to accumulate on the floodplain. The arundo is now substantially controlled, but the effect of sediment accumulation still exists. The edge of the floodplain is now 118 feet above sea level compared with the water surface elevation of 109 feet. The 9 feet of floodplain height above the water surface inhibits floodplain function and prevents the natural establishment of native vegetation by seed drop because depth to ground water exceeds the growth rate at which seedlings can establish before the heat of summer.
