Above Pathfinder Subbasin Aquifer Systems

 
 

An aquifer is defined as a geologic formation that is sufficiently water-saturated and permeable to yield a significant quantity of water to wells or springs. The aquifer systems of the Above Pathfinder subbasin are shown on the following map. Aquifer systems currently used and/or available for future use in the Above Pathfinder subbasin include the following:

  • Quaternary Aquifer System (Alluvial deposits);
  • Late Tertiary Aquifer System ( Browns Park, Arikaree, and White River Formations;
  • Early Tertiary Aquifer System ( Wind River, Hanna, and Ferris Formations);
  • Late Cretaceous Aquifer System (Medicine Bow, Mesaverde, and Frontier Formations);
  • Early Cretaceous Aquifer System (Muddy Sandstone and Cloverly Formation);
  • Triassic-Jurassic Aquifer System (Sundance Formation);
  • Late Paleozoic Aquifer System ( Casper Formation/Tensleep Sandstone);
  • Early Paleozoic Aquifer System (Flathead Sandstone); and
  • Precambrian Aquifer System (Precambrian crystalline bedrock units).

The Quaternary, Late Tertiary, Early Tertiary, Late Cretaceous, and Late Paleozoic Aquifer Systems are the most developed aquifer systems for high capacity wells within this subbasin.

The Platte River Basin Plan is a planning tool developed for the Wyoming Water Development Office. It presents estimated current and estimated future uses of water in WyomingÆs Platte River Basin. The Plan is not used to determine compliance with or administration of state law, federal law, court decrees, interstate compacts, or interstate agreements.
