Colusa Basin Watershed Assessment

May contain: nature, water, outdoors, grass, plant, land, and tree

The Colusa County RCD was granted funding through the Department of Water Resources (DWR) as an implementing agency for the CALFED Bay Delta Watershed Program grant under the Water Security, Clean Drinking Waters, Coastal and Beach Protection Act of 2002 (Proposition 50) for developing and implementing the Colusa Basin Watershed Assessment.

The Colusa Basin Watershed (Basin) envelopes the upper portion of Yolo County, the majority of Colusa County, and the southern part of Glenn County with all the major tributaries draining into the Bay Delta in one way or another.

The Colusa Basin Watershed Assessment can be characterized as a “current conditions report”, and will help to illustrate where there are information gaps, what changes have occurred in the basin, why these changes happened, if they were good changes or bad changes, land use patterns, social characteristics, and more. The consulting firm H.T. Harvey and Associates worked on the information gathering process for the Assessment. The idea was, not to reinvent the wheel, but to make it more functional. Our hope is that this working document will assist local stakeholders in making informed land management decisions that will improve the holistic health of the watershed.
