California Irrigation Management Information System (CIMIS)

The California Irrigation Management Information System (CIMIS), a standardized accounting for water consumed through evapotranspiration by the soil and plants, is designed to help growers develop efficient water budgets and irrigation strategies by providing scheduling information matching the amount of water applied to a crop with needs of the plant.

The California Irrigation Management Information System (CIMIS) is a network of over 145 automated weather stations managed by the California Department of Water Resources. Developed in 1982 by the DWR and the University of California, Davis it was designed to assist irrigators in managing their water resources more efficiently saving water, energy, and money.

The CIMIS stations in this area are:

  • #206 Denair
  • #148 Merced
  • #161 Patterson
  • #71 Modesto

For more information about how to use CIMIS, visit the Department of Water Resources CIMIS website.

The Fresno State Center for Irrigation Technology hosts the Wateright website at http://wateright.org providing free irrigation scheduling programs and tutorials that can be used to develop irrigation schedules using CIMIS data. Additionally, the CIMIS site provides links to other irrigation scheduling programs (some of which must be purchased) and resources.

For more information about these programs, please call (209) 883-8386.
