Cedaredge, Colorado, United States

Walker Water designs and develops irrigation water conservation software for the Western Slope of Colorado. Features include the administration of ditch flow and reservoir decrees, evaporation, water drainage and flow mapping, and seep monitoring. Systems are tied into real-time SCADA measurement devices to collect and display water information in a dashboard setting with alarms and other online notification features.The benefits are direct water savings through better management and control of flow and distribution throughout the irrigation district. Better managed water is water that is protected for current day users and future generations.
