Shaun Wicklein Bryan Pula 2022 Between April 2010 and May 2019, springflow was determined for a midchannel spring in Jackson River below Gathright Dam near Hot Springs, Virginia. The springflow was measured to assess if the spring was influenced by the elevation of Lake Moomaw. Local precipitation was also reviewed to determine whether variations in springflow were influenced by rainfall. The spring is approximately 250 feet downstream from the dam’s discharge race channel, where the water is carried away from the base of the dam, and its flow was determined by the gain in streamflow between concurrent measurements made upstream and downstream from the spring. Throughout the study period, the springflow showed little variation over time, and no direct correlations were determined between the observed springflow and the elevation of Lake Moomaw or local precipitation data. application/pdf 10.3133/ofr20221047 en U.S. Geological Survey Summary of the midchannel springflows in Jackson River below Gathright Dam between April 24, 2010, and May 7, 2019 reports
