Description: The base of the aquifer was defined by the correlation of lithologic logs across the aquifer area.

Description: The 2013 potentiometric surface map was interpolated from 140 wells completed in the Canadian River alluvial aquifer, measured between January and March of 2013. The water-table surface is shallow, typically less than 30 feet below land surface. The measured water levels were supplemented by additional water levels from completion reports provided by the OWRB to the USGS. Analysis of the water-table surface map indicates that groundwater flows from the surrounding bedrock units towards the alluvial deposits and main river channel.

Description: The OWRB Aquifers dataset is to be used as a general reference as to the extent of the major aquifers in Oklahoma. It was created with multiple sources of information. The scales and accuracy of these sources vary. This map layer shows the general outlines of the principal bedrock and alluvium aquifers in Oklahoma. The three main sources for aquifer boundaries were from the Oklahoma Water Resources Board, the Oklahoma State Department of Health, and the United States Geological Survey. This map layer is intended to be used for display purposes, and should not be used for local data analysis.
