The Colorado Water Rights Administration Tool (CWRAT) is a software tool that can be used by State of Colorado Water Commissioners to edit water administration data, including river calls and daily water balance Water Information Sheets. CWRAT is essentially the same as the StateView software with an additional Administration menu. CWRAT is written in Java.
CWRAT currently is used in a limited fashion. It is hoped that some of its components such as the Water Information Sheets can be utilized in other tools in the future. Users typically use the State of Colorado's Division of Water Resources website or the StateView software to view HydroBase contents.
