Publication Date


Sando, R., Olsen, T.D., Kaiser, K.E., Haluska, T.L., and Hockman-Wert, D.P., 2018, Physical CPGs -- Probability of Streamflow Permanence (PROSPER) Continuous Parameter Grids (CPGs): U.S. Geological Survey data release,


These datasets are continuous parameter grids (CPG) of soil data in the Pacific Northwest. Datasets include available water capacity, depth to water table, hydrologic soil group percentage, and soil component (e.g., clay, silt, sand) percentage. Source data come from the Digital General Soil Map of the United States, produced by the Natural Resources Conservation Service, United States Department of Agriculture.

These Continuous Parameter Grid (CPG) rasters were generated as inputs to the PROSPER model, predicting the probability of streamflow permanence throughout the Pacific Northwest. Each model predictor variable (parameter grid) was converted from its original spatial form into a CPG, which combines the discrete values with a flow accumulation raster, thereby converting the predictor values into a spatially moving average format.
