The CWCB appropriates and acquires water rights to preserve and improve the natural environment of streams and lakes in the state. The agency also provides protection and monitoring of the state’s instream flow water rights. Since 1973, the CWCB has appropriated instream flow water rights on more than 1,500 stream segments covering more than 8,500 miles of stream and 477 natural lakes.

Standardized field and office procedures help to ensure that instream flow recommendations reflect the amount of water required to preserve and improve the natural environment. The R2CROSS tool is one of the standard techniques employed by state and federal agencies to model instream hydraulic parameters and develop instream flow recommendations in Colorado.
