East Branch North Fork Feather River Spanish Creek and Last Chance Creek Non-Point Source Water Pollution Study, Section 205(j)(2): Clean Water Act

Title
East Branch North Fork Feather River Spanish Creek and Last Chance Creek Non-Point Source Water Pollution Study, Section 205(j)(2): Clean Water Act
Abstract
Erosion and sedimentation in the East Branch North Fork Feather River (EBNFFR) are impairing fisheries, water based recreation, aesthetics, water diversions for domestic and irrigation uses, downstream hydroelectric and State Water Project users. The Last Chance Creek subwatershed is estimated to contribute 9.5 percent of total sediments in the EBNFFR and the Spanish Creek subwatershed is contributing 20.3 percent of total sediments to the EBNFFR according to the 1988 SCS Erosion Inventory study. Declining water quality and eroding stream banks are desertifying meadows, lowering property values and reducing the productivity of Plumas County's agricultural, hydroelectric, and recreational economic base. This study has assessed and evaluated existing pollution sources in the Last Chance and Spanish Creeks. Study results have been used to develop geomorphic structural and vegetative erosion control measures for project sites in each of these sub-watersheds.
Purpose
To develop a coordinated, comprehensive approach to sediment and erosion assessment and control in the East Branch North Fork Feather River (EBNFFR), to evaluate sediment sources and erosion control management practices in the Spanish Creek and Last Chance Creek tributaries to the EBNFFR, to develop treatment parameters (structural and management) for priority areas in the Spanish and Last Chance subwatersheds, to develop site specific designs for at least one priority area in each of those subwatersheds, and to develop a list of potential investors and contacts for erosion and sediment control projects in the EBNFFR.
