The State Line Gauge is responsible for monitoring water flows from Wyoming into Nebraska. A litigious past has resulted in settlements on the quantity of water each state receives and what that water is used for, whether it’s irrigation, recreation, power generation or wildlife habitat. Looking upstream from the monitoring station, one camera watches the last of the North Platte water as it passes into Nebraska. As a braided river does, the meandering channel is threatening to overtake the south bank, bypassing the weir, where water is measured. Construction to prevent this erosion occurred in 2013. A second camera faces downstream, looking at the weir itself.
