Abstract:

The Upper Pierre aquifer (UPA) is a partially defined and largely unexplored aquifer located in Colorado, Nebraska, Kansas and Wyoming.  The UPA is in the upper portion of the Piera Shale Formation below the transition zone of the Fox Hills Formation (the bottom of the Denver Basin aquifer sequence).  It is a fine-grained sandstone, siltstone with thickness ranging up to 1000 feet in some areas.  Wells installed in the aquifer produce between 100 and 300 gallons per minute.

This talk will discuss where the aquifer is currently known to exist, the history of the exploration, water court cases, the COGCC study, cross sections developed by the State Engineers Office, independent research, how the resource is important to the Colorado Water Plan and the next steps.
