Around 1942, river otters were officially considered gone from the Hoosier state. For the next 50 years, few, if any, otters were seen here.
Then, the Indiana Department of Natural Resources began to reintroduce these interesting mammals to various parts of the state. Beginning in 1995, biologists acquired 303 river otters from Louisiana and started releasing them in 12 various sites in northern and southern Indiana.
After being gone for over half a century, otters were reappearing in their historic range.
