Norton Dam

Overview
Norton Dam is constructed in a narrow section of the Prairie Dog Creek Valley where erosion resistant outcrops of the Ogallala Formation occur in both abutments.  In the valley floor, Pleistocene erosion has removed the Ogallala Formation and exposed bedrock of the Niobrara Formation.  Approximately 70 to 75 feet on unconsolidated Holocene alluvium and Wisconsin age terrace deposits overlie the Niobrara.
