- Accurate estimates of connecting channel flows are a vital component of water management in the Great Lakes basin. As part of the IUGLS, new hydrometric (water quantity) gauging stations were installed on each of the connecting channels of the upper Great Lakes. This included horizontal acoustic Doppler current profilers (ADCPs) on the St. Marys, St. Clair and Detroit rivers used to estimate flow from measurements of stage and cross-sectional velocity, and a new stage (water level) gauge installed on the upper Niagara River to estimate flows from relationships between stage and discharge. Continued operation of these stations after the IUGLS is completed will provide key data to help Canada and the United States manage the Great Lakes under a changing climate regime.
