The Cosumnes and Mokelumne River Floodplain Integrated Resources Management Plan (IRMP) is a multi-partner effort designed to develop a management strategy to facilitate the effective enhancement of floodplain conditions and functions of the lower Cosumnes and Mokelumne rivers. Partners for the CMIRMP include the Southeast Sacramento County Agricultural Water Authority (SSCAWA), Sacramento County Water Agency (SCWA), East Bay Municipal Utility District (EBMUD), Sacramento Area Flood Control Agency (SAFCA), The Nature Conservancy (TNC), San Joaquin County Resource Conservation District (SJCRCD), Reclamation District 800, and Center for Integrated Watershed Management - University of California, Davis.

The study partners have identified representatives from each of their organizations to form an Oversight Committee (Committee) for the project. The Committee serves as the decision making body for the CMIRMP and has the responsibility of ensuring that projects goals and objectives are met throughout the planning process. The Committee has developed the following goals and objectives for the CMIRMP.


  • Engage stakeholders in the development of an Integrated Resource Management Plan (Plan).
  • Incorporate the principles of adaptive management in an implementation and monitoring strategy that will be developed as a component of the Plan.
  • Develop a Plan to guide implementation of prioritized management actions that will effectively enhance floodplain and riparian habitats, flood management, and groundwater recharge along the lower Cosumnes and Mokelumne rivers


  • Develop a public outreach program that will inform, engage, and seek feedback from local stakeholder groups and landowners within the study area.
  • Identify and organize focus groups composed of local stakeholders having expertise or interest for each river reach of the study area.
  • Develop a prioritization model that facilitates selection of opportunities for enhancement, consistent with the project's goals and objectives, and that will remain functional and adaptable to future conditions.
  • Identify opportunities to protect and enhance floodplain, riparian, and riverine ecosystems.
  • Identify opportunities to improve flood management and reduce flood damage to structures, levees, and agriculture.
  • Identify opportunities to increase groundwater recharge associated with the floodplains.
