Green - Gaining
Red - Losing
The animations depict “apparent” gaining and losing reaches in Nebraska, based on Nebraska DNR and USGS stream gage data. “Apparent” gains or losses are calculated from gaged flows only, and may be influenced by ungauged tributaries or canal diversions. Green reaches indicate that more water is coming into the reach than is leaving the reach (gaining condition) and red indicates the opposite (losing) condition. The width of the lines indicate the magnitude of apparent gains or losses within a given month. Data from June 2015 through June 2016 were used to construct the animation.
