Fact Sheet and Map

The Mid San Joaquin River Regional Flood Management Plan (RFMP) is being updated throughout 2021 through the participation of a range of stakeholders primarily from Stanislaus County. The result of the effort will be a updated vision for a safer and more flood-resilient region that identifies challenges and opportunities for flood management and a prioritized list of actions for DWR to consider in their Central Valley Flood Protection Plan. The RFMP Update will identify priority flood protection projects for stakeholders to pursue. This regional planning effort was created to give stakeholders the opportunity to develop a plan to reduce flood risks in the area from the confluence of the Merced and the San Joaquin Rivers to the confluence of the Stanislaus and the San Joaquin Rivers. The Mid San Joaquin Region is one of six DWR flood management plan regions in the Central Valley.

The Mid San Joaquin River RFMP includes the following sections:

  • Executive Summary
  • Regional Settings
  • Assessment of Flood Hazards in the Region
  • Proposed Regional Improvements
  • Regional Priorities
  • Enhanced Operations and Management
  • Emergency Response Planning
  • Land Use and Environmental Enhancements
  • Regional Financial Plan
  • Updated Regional Atlas (separate document or attachment)

Through this locally-driven process, stakeholders will have an opportunity to identify the flood management opportunities in the region, ranging from measures appropriate on agricultural lands to actions designed for more developed zones in the communities of the region. Participants include local, state and federal government agencies, flood control agencies, irrigation districts, reclamation districts, levee maintenance districts, agricultural interests, landowners, community groups, as well as recreation and environmental interests. The Mid San Joaquin River RFMP offers local and regional interests, large and small, the opportunity to provide direct input to the state’s process about specific project opportunities and challenges. The RFMP also provides regional interests with a process in which they can frame, identify, and begin to address their own flood management goals. Ultimately, the Mid San Joaquin River RFMP  has been a critical foundation needed to cultivate collaboration among stakeholders and successfully position the region for future funding opportunities.
