About Us

The Mid San Joaquin River Regional Flood Management Plan (MSJR RFMP) was developed from March 2013 to December 2014 through the participation of a range of stakeholders primarily from Stanislaus County. The result of the effort is a vision for a flood-safe region that identifies challenges and opportunities for flood management and a prioritized list of actions for DWR to consider in their Central Valley Flood Management Plan (CVFMP). It will also 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.

Through this locally-driven process, stakeholders had 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 distractions, reclamation districts, levee maintenance districts, agricultural interests, landowners, community groups, as well as recreation and environmental interests. The final plan captured input from these diverse interests to identify prioritized projects, including a cost/ benefit assessment for each project. Ultimately, the Mid SJR RFMP is the critical foundation needed to cultivate collaboration among stakeholders and position the region for future funding opportunities.

Due to the success of the MSJR RFMP, the process is being extended to continue work with regional and watershed stakeholders. The outcome of this second phase of RFMP work will result in coordinated efforts for ongoing flood management, emergency response and operations and maintenance for the region. There will also be a focus on addressing institutional barriers associated with inter-regional environmental permitting approach, technical assistance for levee repairs and maintenance, levee modification approaches and channel maintenance approaches.

Planning Area Map

The Mid SJR region extends from the Merced-San Joaquin River confluence to the Stanislaus-San Joaquin River confluence.  Specifically, any areas protected by the State Plan of Flood Control facilities, and any other areas experiencing flood issues that have a nexus to these facilities, will be eligible for inclusion in the MSJR RFMP.
