Raster showing change in water-table altitude between Fall of 2002 and Fall of 2015 in the alluvium in the Lower Arkansas River Valley, Southeast Colorado. Hereafter "fall" is defined as June 1 to November 30. All interpolation and geoprocessing was done using ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011).

Raster dataset showing saturated thickness (in feet) of the alluvium in the Lower Arkansas River Valley, Southeast Colorado, June 1 - November 30, 2008 (hereafter defined as "fall"). Saturated thickness values based on water levels measured in the study area and median lake level at John Martin Reservoir during this time period. Surface interpolations for water-table altitude were done using Inverse Distance Weighting using coordinate and altitude data from "Wells and water-level altitude in the alluvium in the Lower Arkansas River Valley, Southeast Colorado, Spring and Fall 2002, 2008, and 2015" (see cross reference section in metadata), and surface interpolation of bedrock was done using Topo to Raster using elevation...

Data release containing geospatial data and metadata for select hydrogeologic characteristics of the alluvium in the Lower Arkansas River Valley, Southeast Colorado, 2002, 2008, and 2015. This data release accompanies U.S. Geological Survey Scientific Investigations Map 3378 (https://doi.org/10.3133/sim3378). Geospatial datasets and metadata include: - Rasters showing estimated thickness of the alluvium; fall-to-fall and spring-to-spring water-table altitude change, 2002 to 2008, 2008 to 2015, and 2002 - 2015; and estimated saturated thickness in the alluvium, fall and spring 2002, 2008, and 2015. - Shapefiles showing bedrock contours underlying the alluvium; the outline of the study area and John Martin Reservoir...

This raster dataset shows the thickness of the alluvium in the Lower Arkansas River Valley, Southeast Colorado. The bottom boundary defined by bedrock (Hurr and Moore, 1972; Nelson and others, 1989a, b, c) and top boundary defined by land surface from U.S. Geological Survey National Elevation Dataset (2016). All interpolation and geoprocessing was completed in ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011).

Contours (20-foot interval) showing altitude of the bedrock surface in feet above NGVD 29 underlying the alluvium in the Lower Arkansas River Valley, Southeast Colorado. Source contours scale was 1:62,500. All digitizing and geoprocessing was done using ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011)
