Stuhlmuller Vinyeards Gravel Skimming

Stuhlmuller Vinyeards Gravel Skimming

Project is limited to the excavation and removal of gravel from a large gravel bar on the Russian River in order to provide juvenile fish habitat and improve channel capacity in order to reduce erosive forces on the opposing stream bank. The northern excavation is intended to lower a high spot in the high flow channel on the back (east) side of the gravel bar. The peak of the high spot is about 1 meter above the elevation of the upstream and downstream sections of the back channel and will be lowered to an elevation consistent with the surrounding gravel bar area. the southern excavation will begin at an elevation approximately 1 foot above summer time base flow elevation and rise up sharply to connect with an existing backflow channel on the eastern side of the bar. Approximately 1000 cubic yards of gravel will be removed from both the southern and northern excavation sites (2000 cubic yards total). The bar will be accessed from an existing road and vegetation removal will be limited to small brushy willows, grasses and forbs occurring on the excavation sites. Material from the excavation will be transported to the Stuhlmuller vineyard on the west side of the river and used to fill upland erosion features currently impacting the vineyard. Any additional spoils will not be placed in the riparian area. Issuance of a Streambed Alteration Agreement No. 1600-2012-0357 is pursuant to Fish and Game Code Section 1602.
