River Otter

The river otter is a mostly aquatic furbearer thought to have occupied one of the largest geographic areas among North America’s mammals at time of European Settlement.  However, the river otter suffered population declines resulting in the loss of nearly 75% of their range by 1988.  Reintroduction efforts throughout North America have led to a successful rebound of this once widely distributed mammal.  River otters occur in several streams, rivers and marshes within eastern South Dakota.  

River otters are secretive in their behavior but are active year-round during the evening and from the hours of dawn to midmorning.  They range in size from 34 to 54 inches in length and their weights can range from 7.4 to 34 lbs.  They are characterized by a cylindrical-shaped body with short legs; a rudder-like tail; short, dense fur; and feet that are completely webbed and adapted for an aquatic lifestyle.

In 2020, the river otter was taken off South Dakota’s state threatened species list.  This delisting has allowed for a conservative trapping season; the first in modern times.  This trapping season runs from November 1, 2020 to December 31, 2020 or until the conservative harvest limit of 15 river otters has been reached (whichever comes first).

To report a harvested otter during the designated trapping season, please call 605.353.7319.

Once this harvest is reported, the trapper will be directed to call a GFP Wildlife office to set up a time to check in the river otter carcass and receive their CITES tag for the detached river otter pelt.
