The Surface Water Supply Index (SWSI) is used as an indicator of surface water supply conditions in Colorado. The SWSI compares the total volume of water in a basin or sub-basin against the volume available in the same month of historical years. Depending on the month, the volume is a combination of streamflow, streamflow forecast, and reservoir storage. The SWSI is calculated for Colorado’s river basins and sub-basins; this data set provides information on the Colorado’s sub-basin-level SWSI calculation.

The SWSI compares the total volume of water in a basin or sub-basin against the volume available in the same month of historical years. Depending on the month, the volume is a combination of components: streamflow, streamflow forecast, or reservoir storage. The SWSI is calculated for Colorado’s river basins and sub-basins; this data set provides information on the Colorado’s sub-basin-level SWSI calculation.
