Drought Monitoring Links

Drought is a constant threat for growers in the Central Valley. These links will provide growers with access to important sites related to drought monitoring 


The California Department of Water Resources (DWR) was established in 1956 and 'is responsible for managing and protecting California's water resources. DWR works with other agencies to benefit the State's people and to protect, restore, and enhance the natural and human environments.' The DWR manages a significant portion of the state's water supply including the State Water Project. The department's website provides information about the California Water Plan, flood management, dam safety, and groundwater protection, as well as other topics. The California Irrigation Management Information System (CIMIS) is a program unit of the Water Use and Efficiency Branch that manages over 145 weather stations throughout the state that collect publicly available data about soil and air temperature, relative humidity, precipitation, and evapotranspiration. The California Data Exchange Center, which is also housed at the DWR site, maintains an extensive collection of hydrologic data including: current river conditions, snow reports, and reservoir storage.
