Publication Summary

As asked by the Central Region Office (CRO), the author reviewed a water-right application by the city of Leavenworth for a well located about 120 feet from the Wenatchee River. The CRO believed the well would be in hydraulic continuity with the river. They were concerned that pumping from this well would deplete streamflow of the Wenatchee River, especially during low-flow periods. Specifically, would the river likely provide over 50 percent of the water pumped from the well? At the time of this investigation, the CRO regulated wells in hydraulic continuity with surface water only when the water captured from the surface water was greater than 50 percent of the volume pumped.
