These data (vector and raster) were compiled for spatial modeling of salinity yield sources in the Upper Colorado River Basin (UCRB) and describe different scales of watersheds in the Upper Colorado River Basin (UCRB) for use in salinity yield modeling. Salinity yield refers to how much dissolved salts are picked up in surface waters that could be expected to be measured at the watershed outlet point annually. The vector polygons are small catchments developed originally for use in SPARROW modeling that break up the UCRB into 10,789 catchments linked together through a synthetic stream network. The catchments were used for a machine learning based salinity model and attributed with the new results in these vector GIS datasets. Although [...]

The purpose of the vector spatial data are to allow users to access the salinity model results for areas of the Upper Colorado River Basin. The model results help identify watersheds that may be contributing more salinity to surface waters. There are also data indicating which watersheds are likely to be contributing salinity due to flood irrigated agriculture or surface land disturbance. A comparison to a previous model is also provided in one of the feature classes that allows users to ascertain how this new model differs from previous similar efforts. The purpose of the raster data were to allow for independent variables to be calculated for all watersheds in the Upper Colorado River Basin to enable salinity yield model building.
