Gauge Description:

Visit https://www.mnpower.com/Environment/WaterTable and look at Thomson Dam for current flow.

Call (after 7AM each day) 1-800-582-8529 or (218)720-2777 to get the flow info through the two dams. The Scanlon and Thompson flows are the last 2 on the message.

Generally the lower will flow at a minimum of 650 cfs until about June 1. Additional releases are typically scheduled one or two weekends each in June, July, and August, subject to in-flow constraints) at flows typically on the order of 475-1000 cfs.

Section down to Swinging Bridge is marginally runnable at 'fish flow' of 350 cfs which is virtually always present.

Min and Max figures reflect flows desirable for running the entire reach. Higher flows are paddleable with discretion.
