6. Wetland Water Level

Water level in centimeters (15-minute averages). The Black Gum Swamp and smaller Beaver Swamp act to buffer flow in the Nelson and lower Bigelow watersheds. The Black Gum Swamp is the source of Nelson Brook and has no significant stream inputs; while Bigelow Brook flows through the Beaver Swamp.  Water levels in these wetlands (especially the BGS) provide an indication of below-ground water storage during dry periods.
