The two exceptions are the Thomson Dam and Prairie River Dam which display the flow through the dam into their bypass reaches. Due to the unpredictable nature of stream flow, reservoir elevations, and periodic technical difficulties, Minnesota Power cannot guarantee the accuracy of the information displayed.
