The exception to this rule is Thomson Dam which only displays the flow through the dam into bypassed reach through Jay Cooke State Park. Due to the unpredictable nature of stream flow, reservoir elevations, and periodic technical difficulties, Minnesota Power cannot guarantee the accuracy of the information displayed.
