Minnesota. Department of Natural ResourcesThe Mt. Simon-Hinckley aquifer is the deepest bedrock aquifer in south-central/southeastern Minnesota, including the Minneapolis-St. Paul metro area. The aquifer is often overlain by sand and gravel, and bedrock aquifers which provide ample groundwater. The margins of the Mt. Simon-Hinckley aquifer have been identified as areas of focused recharge. Near the margins, the Mt. Simon-Hinckley aquifer may be the only available groundwater source. State statutes limit present use, protecting the aquifer as last resort for the future.This product can be used to identify the areal extent of the protected Mt. Simon-Hinckley aquifer. When combined with other bedrock and Quaternary geological data, it can be used to identify areas where the Mt. Simon-Hinckley aquifer may be the only usable groundwater source or where shallower usable sources are available. This GIS extent coverage can be used for planning, management, scientific, and other purposes.data were acquired February 2022Filesgeos-mtsimon-hinckley-aquiferengPublicAreal extent of the Mt.
