RIVER OTTERS. River otter were abundant in Iowa during European settlement. The FUR TRADE and loss of habitat caused them to be lost to the state.

Wildlife managers began reintroduction efforts in the 1970s. Iowa’s river otter reintroduction was begun in 1985 at Red Rock Reservoir. Sixteen otters from Louisiana were released. These otters survived normally and releases were continued until 2003.

In total 345 otter were released in Iowa between 1985 and 2005. This reintroduction with wetland restoration and conservation contributed to the growth and widespread distribution of otters in Iowa.
