Depending upon the type of groundwater use and desired well water quality and quantity, subbasin aquifer systems have potential for future development. A map of potential groundwater development sites for the Pathfinder to Guernsey subbasin area is included below. The future development potential of the major aquifer systems located within the Pathfinder to Guernsey subbasin is summarized below:

• The Quaternary Aquifer System yields large quantities of groundwater to wells, but, because it is considered to be hydrologically connected to the North Platte River and its tributaries, development potential for this aquifer system is limited. Water quality and susceptibility to contamination need to be assessed on a local basis.
  
  
• The Late Tertiary Aquifer System has been developed for irrigation, stock, and domestic supplies in the Pathfinder to Guernsey subbasin and has future development potential in the southernmost areas of the subbasin.
  
  
• The Late Paleozoic Aquifer System has been identified as a potential source for groundwater development in this subbasin, particularly for municipal use. Development of this aquifer system will likely require demonstrating that the well is not hydrologically connected to the North Platte River and its tributaries. Development of this aquifer system will require a site-specific hydrogeologic investigation prior to well drilling to assess development potential.
