Watershed Overview

Current & Past RCD Programs:


  • The RCD has worked with many agricultural producers in Maacama Watershed to enhance their farming operations and protect soil and water resources. Projects include the development of LandSmart Plans, implementation of frost protection alternatives, enhancement of riparian areas, erosion control, and hedgerow plantings.

Watershed Scale Planning

  • Maacama and Mark West Integrated Watershed Management Plan: The RCD is developing a comprehensive Integrated Watershed Management Plan for the Upper Mark West and Maacama Creek Watersheds. This plan will integrate and update the draft Upper Mark West Management Plan and the completed Maacama Watershed Plan. To complete this plan, the RCD is working with landowners and other stakeholders throughout the watershed to investigate and evaluate current and historic conditions and recommend a prioritized set of actions and programs to improve water quality and riparian and aquatic habitat conditions. This effort builds off of the RCD’s completion of the Maacama Watershed Assessment in 2005.

Water Resource Management

  • As one of our district’s major winegrowing areas, and as an area where water conservation has been deemed a high priority, Maacama is one of the focal areas of our Vineyard Irrigation Evaluations. This service is currently available on a fee for service basis.


  • To mitigate for impacts of two bridges CALTRANS replaced along Hwy 128 in 2010, the Bidwell Creek Riparian Enhancement Project was developed and identified for implementation by the RCD. This project which, will start implementation in the winter of 2016-17 will install two hundred (200) riparian trees and shrubs along 930 feet of Bidwell Creek, a salmonid bearing stream.
  • The RCD is actively working with landowners to develop and implement projects to enhance riparian and instream habitat and stabilize eroding stream banks.
  • As part of the Rural Road Improvement Program the RCD is currently working with landowners to assess unpaved roads to identify sites posing a risk of sediment delivery to nearby streams.
  • 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.
