Watershed Overview

Current & Past RCD Programs:

 

Planning

  • The RCD has worked with many agricultural producers in Alexander Valley to enhance their farming operations and protect soil and water resources. Projects include the development of LandSmart Plans, enhancement of riparian areas, and erosion control.

Water Resources

  • As one of our district’s major winegrowing areas, and as an area where water conservation has been deemed a high priority, Alexander Valley is one of the focal areas of our Vineyard Irrigation Evaluation program. This service is currently available on a fee for service basis.
  • The RCD has also worked with the Russian River Property Owners Association to develop an ongoing landowner-driven monitoring program to assess spring and summer streamflows in the mainstem of the Russian River in Alexander Valley.
  • The RCD is very involved in a statewide groundwater monitoring effort called the California Statewide Groundwater Elevation Monitoring (CASGEM) program. This program was created by SBx7 6 and established for the first time a statewide program to collect groundwater elevations, facilitate collaboration between local monitoring entities and the Department of Water Resources, and to report this information to the public. The Sonoma County Water Agency (SCWA) and the County Permit Resource Management Department have assumed responsibility for collecting these data in the basins throughout Sonoma County. The RCD was hired in 2011 by the Water Agency to conduct outreach to gain landowner participation in the CASGEM program and then to collect groundwater elevation data for these various wells covering the Dry Creek Valley, Alexander Valley and the Lower Russian River basins. Groundwater data are collected on local landowner wells twice a year in the various basins and reported back to the Sonoma County Water Agency and the Department of Water Resources.

On-the-Ground Projects

  • The RCD will be finishing its final year of the Arundo donax removal program. The remaining 150 acres of property bordering the Russian River will be sprayed and monitored. Implementation was made possible by the Department of Water Resources Proposition 84 Integrated Regional Water Management program. Arundo donax is a fast-growing, non-native bamboo like grass that invades riparian areas and displaces native vegetation in the Russian River Watershed. This large weed absorbs soil moisture, shades out native plants, presents a significant fire hazard, and threatens the viability of numerous fish and wildlife species. The RCD has treated over 1200 infested acres of Arundo in Alexander Valley and has replanted many of these treated areas with native riparian plants and trees. (Click here for Informational Brochure).
  • The RCD continues to implement projects identified through outreach and stream assessments in the “Habitat Restoration and Conservation Plan for Anadromous Salmonid Habitat in Selected Tributaries of the Russian River Basin” in Alexander Valley, Dry Creek Valley, and Knights Valley.

Agricultural and Environmental Education

 

  • FARMS Leadership Program field days are held on private agricultural properties within the watershed.
