New USGS Report Describes Processes and Misconceptions
Concerning the Effects of Groundwater Pumping on Streamflow
Groundwater provides drinking water for millions of
Americans and is the primary source of water to irrigate cropland in many of
the nations most productive agricultural settings. Although the benefits of
groundwater development are many, groundwater pumping can reduce the flow of
water in connected streams and rivers—a process called streamflow depletion by
wells. The USGS has released a new report that summarizes the body of knowledge
on streamflow depletion, highlights common misconceptions, and presents new
concepts to help water managers and others understand the effects of
groundwater pumping on surface water.
