Senay 20130626 raster digital data U.S. Geological Survey Data Series 777 Reston, VA. U.S. Geological Survey https://pubs.usgs.gov/ds/777 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. The Purpose of this geodatabase is to present selected raster data from the Water-Budget-Components report.

Oklahoma City OK 73116 USA (405) 843-4410 (405) 843-7712 dryter@usgs.gov 7:30 am - 4:30 pm Central time zone In the Stanton and others (2011) report, the authors used this raster to compute average annual recharge in inches and volume in million acre-feet for each of the eight states that make up the High Plains (Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming), and for each of the three commonly defined regional zones (northern High Plains, central High Plains, and southern High Plains). The average annual recharge was computed using the following method. The active raster cells were converted to points and then spatially joined to the areal polygons representing the state and regional polygons in the ESRI Arc GIS 9.3.1 software. Next, all of the points that fell inside the active areas (the areas of NODATA where the aquifer is not present were excluded), were summarized to get an average rate for each zone. The average annual volume of recharge in million acre-feet was computed by multiplying the average annual recharge in inches by the area in acre feet of the zone and then dividing by a million. Area in acre feet for the zones are defined as follows: Colorado 8,523,000 Kansas 19,745,000 Nebraska 41,379,000 New Mexico 5,963,000 Oklahoma 4,735,000 South Dakota 3,106,000 Texas 23,209,000 Wyoming 5,183,000 Northern High Plains (NHP) 61,655,000 Central High Plains (CHP) 31,428,000 Southern High Plains (SHP) 18,759,000 2011 Jennifer S.
