DS-777 Average Annual Recharge, 2000 to 2009, 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.
