In response to decreasing water levels in the Great Lakes, especially Lake Michigan and Lake Huron, the International Upper Great Lakes Study (IUGLS) asked USGS to continuously measure flows in the connecting channels of St. Marys, St. Clair, and Detroit Rivers, and Water Survey Canada (WSC) to measure flows of Niagara River. To accommodate the effects of variable backwater and the unsteadiness of flows in the upper channels, the USGS deployed fixed-location acoustic Doppler velocity meters (ADVM) to continuously monitor water velocities at a point along each of these channels, along with water levels.
Velocity and water-level data were initially related to channel flows through a series of acoustic Doppler current profiler (ADCP) flow measurements beginning in 2008. Continuous flow information based on these data became available for St. Clair and Detroit Rivers in 2009, and for the St. Marys River in 2010. These velocity-stage-flow relations are continually monitored and refined as additional data become available. The International Joint Commission currently provides funding needed to support data collection and analysis at these streamgages. Classification of these streamgages as International Gaging Stations would help secure long-term funding and operation.
