Abstract

This project seeks to determine the relation between surging surface flow and projected groundwater declines at the Great Sand Dunes National Monument. Surging flow in Medano Creek is a unique visitor attraction at the Monument, and is exhibited from April through July at easily accessible sites. Projected water table declines of up to 46 m due to an adjacent groundwater development scheme may increase infiltration rates in Monument creeks, thus leading to diminished or eliminated surge flow. This report covers the third 6-month period of the contract (May 15-Nov. 15, 1992).
