TR 2 - Estimated Average Annual Water Balance for Piceance and Yellow Creek Watersheds, I.F. Wymore, August 1974

This report provides a surface water balance estimate by elevation zones and vegetation types for the Piceance and Yellow Creeks watersheds. The original purpose of this study was to provide the U.S. Geological Survey with data for checking and calibrating the ground-water model for the Piceance Basin, but the resulting estimates have considerable application in answering plant water use questions related to the developing oil shale industry. The estimates developed are generally consistent with known water balance factors and vegetation indicators, but the water balance model is based on linear relationships to the maximum possible extent and the necessary simplifying assumptions ignore a number of complex relationships.
