In an effort to assess drought impacts and general groundwater conditions, the Colusa County Water Resources Department (Department of Agriculture) is compiling information on well problems county-wide. This information will help in our ongoing efforts to gain a better understanding of the local groundwater system. We are gathering information on all well types (domestic, irrigation, other) and all well issues, whether drought-related or mechanical. If you are experiencing problems with your water well, please take a few minutes to fill out the Report of Well Problems.
