Barren River - Barren River is the largest tributary of the Green River. It flows in a meandering northwesterly path from southern Kentucky through the city of Bowling Green and onto its confluence with the Green River near Woodbury in western Kentucky (photo by Michael Lapina, USACE).

Barren River - At higher flows, floodplains of the Barren River become inundated, which can be both beneficial and problematic for human and natural communities. Understanding floodplain dynamics related to reservoir outflows helps inform release decisions at dams. Image shows Barren River roughly 5 miles downstream of the dam during outflows of approximately 4,600 cfs, March 2017 (photo by Barren River Project Staff, USACE).
River Hydraulics Modeling - The River Analysis System (HEC-RAS) was used to simulate river conditions for a range of flows. Model results (blue, with shallower areas as lighter blues, 6,000 cfs) were compared to aerial photographs (semi-transparent gray tones, 1964, during flows of 5,900 cfs) to investigate channel and floodplain features that constrain release of high flows from Barren River Dam. Image shows Barren River roughly 13 miles below dam.
Barren River - Monitoring rivers over a range of flows helps water managers better understand connections between dam releases and downstream conditions, knowledge which is useful when making operational decisions that affect human and ecological communities. Image shows Barren River roughly 22 miles downstream of the dam during outflows of approximately 4,600 cfs, March 2017 (photo by Barren River Project Staff, USACE).
