Geometry Type: esriGeometryPolygon

Description: This dataset was created or modified by the Colorado Geological Survey (CGS) into this format for use in the Colorado Groundwater Atlas by the following process:Alluvial deposits along streams and rivers throughout Colorado with the potential for forming alluvial aquifers in direct hydraulic connection with surface water are compiled as a statewide feature class. Polygons outlining extent of alluvium along waterways were digitized in a consistent manner at scales between 1:24,000 and 1:50,000 using a combination of available LiDAR, topographic DEM rasters, high resolution satellite imagery, and 1:24,000 scale topographic maps. Where needed, published geologic maps and permitted water well geologic logs were used for verification. This feature class was created in 2020 in ArcGIS for Desktop Version 6.2 (Build 9200); ESRI® ArcGIS 10.6.1.9270.Access / Use Constraints: none
