North Logan City modified a gravel excavation site at the mouth of Green Canyon during the spring of 2011 to retain excess flow from the Green Canyon catchment. From August 2011 to March 2012, the Utah Geological Survey (UGS) monitored water flow into the gravel pit, and recorded gravity data and groundwater levels at several sites within a mile of the gravel pit. The UGS observed a significant increase in gravity from August to September in an area southwest of the gravel pit, which indicates an increase in the amount of water in that region from August to September. Based on the measured increase, water is traveling from the gravel pit towards the region of the principal aquifer of Cache Valley.
