Watershed Management Initiative -- Central Valley Region Chapter

To effectively protect water resources, a mix of point and nonpoint source discharges, ground and surface water interactions, and water quality and quantity relationships must be considered. The complexity of these issues present considerable challenges to water resource protection programs. The State and Regional Water Boards are responding to these challenges with the Watershed Management Initiative (WMI). The WMI is designed to integrate various surface water and groundwater regulatory programs while promoting cooperative, collaborative efforts within a watershed.

The WMI Chapter and Appendices for the Central Valley Region are divided into sections that can be accessed independently, below, or the entire document may be downloaded as one file, 4.3 MB*, PDF (PDF Info).
