From the Department of Water Resources:
The Department of Water Resources (DWR) is receiving public comments on the Public Review Draft Guidelines for Proposition 4 CIMIS Expansion and Site Improvement Project. A 45-day written comment period begins on May 20, 2026, and written comments must be submitted by 5:00 PM PDT on July 3, 2026. Comments can be submitted via email to DWRCIMISPublicContact@water.
The Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024 (Proposition 4) made $75 million available to DWR for projects that increase water conservation in agricultural and urban areas. The California Irrigation Management Information System (CIMIS) provides data that irrigators need to determine crop/landscape water requirements to apply the right amount of water at the right time. Approximately $10 million of the $75 million is planned for the expansion of CIMIS stations network to areas that have spatial data gaps (5.47 million) and improvement of site conditions for existing stations ($3.40 million). The remaining balance ($0.86 million) will be used for program delivery. The CIMIS program will use these funds to purchase and install sensors and equipment for new CIMIS stations to be installed in areas that lack representative stations and to improve site conditions for existing stations that do not meet the standard reference conditions.
How to access the Draft Guidelines:
The draft guidelines are now posted on the Public Notice Page.
