Watershed Reports and Studies
San Luis Obispo County Watershed Management Plan
Through the Integrated Regional Water Management Plan Update, the RCDs of San Luis Obispo County led a watershed planning effort that included characterizing each watershed, identifying data gaps, a draft approach for evaluating conservation countywide, a watershed information, an instream flow study and a percolation study.
The purpose of the SLO County Watershed Management Plan is to grow knowledge and value of watersheds and their related services and to strengthen documentation of issues and needs in an effort to encourage faster implementation of appropriate watershed restoration projects. The outcomes of this project are meant to initiate countywide discussions and encourage public engagement.
