Minong Flowage is a 1,564 acre impoundment of the Totagatic River created by a dam constructed in 1936-37. The majority of the flowage lies in Washburn County, while a small part extends north into Douglas County.

There is a Washburn County park and campground with a boat landing on the western side of the lake. There is also a state-owned boat landing on the eastern side of the flowage and a township-owned unimproved boat landing at the upstream end of the flowage.

The shoreline is nearly entirely privately owned and is well developed. The water is stained brown and is moderately fertile. Most of the bottom substrate is sand. There are exposed tree stumps, especially in the upstream bays. Aquatic vegetation is common in the shallow bays.

The maximum and mean depths of Minong Flowage are 21 feet and 9 feet, respectively. The fishery consists mainly of walleye, northern pike, largemouth bass, bluegill, black crappie, and yellow perch. Smallmouth bass, rock bass, pumpkinseed, black bullhead, yellow bullhead, and carp are also present.

The repairs on the Minong Dam started on April, 2013.  Water had to be taken out so the cement wouldn’t be ruined.  After that the water came down five feet. The Cranberry Dam came down too. The cost of the dam repair was 1.1 million.  The WI DNR  gave $400,000 and Dahlberg Light and Power gave $100,000 in donations to help with the repairs.  Property owners  had to pay a special assessment.

The existing powerhouse that was at the dam has been removed. The old dam that was a high hazard dam. Some risks of not repairing the dam where it can fail or loss of life or property. Six people from Staab Construction came to the dam to repair it. They used 1,200 yards of cement and 55 tons of rerod.  At the end of the project, they found that the mud gates failed. On March 3, 2014 the repairs were done and it was inspected.
