A northern Michigan trout stream that was used for years to support a commercial fish farm is flowing freely again after a dozen small dams were removed.
The Flowing Well Trout Farm, built near Kalkaska, Michigan the mid-1900s, erected 12 small dams to create fish rearing ponds. The dams diverted the north branch of the Manistee River and the Flowing Well Creek, which caused unnaturally high water temperatures, blocked fish passage and disrupted the natural movement of sediment and woody debris in the coldwater trout streams.
Removing the dams restored natural conditions in 37 miles of the streams, which increased the native brook trout population.
