DS-777 Average Annual Recharge, 1940 to 1949, in inches estimated from the Soil Water Balance (SWB) Model for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

The water-budget components geodatabase contains selected data from maps in the,
"Selected Approaches to Estimate Water-Budget Components of the High Plains, 1940
through 1949 and 2000 through 2009" report (Stanton and others, 2011). Data were collected
and synthesized from existing climate models including the Parameter-Elevation Regressions
on Independent Slopes Model (PRISM) (Daly and others, 1994), and the Snow accumulation
and ablation model (SNOW-17) (Anderson, 2006),and used in soil-water balance models to
compute various components of a water budget. The methodologies used to compute the
averages and volumes for the data in this geodatabase are slightly different for different
components and models.
