Social media made the Bluffton Icon aware of river otters being sighted by local photographers. A call from the Ohio Department of Natural Resources confirmed that in recent years the otter population has spread into northwest Ohio.

ODNR Wildlife research technician Sara Zaleski noted that otters seek clean, high quality water and that their presence is a good reflection on area water conditions.

In the early 20th century, otters were trapped out of existence (extirpated) in Ohio. In 1986, they were reintroduced by a program that brought otters to the eastern parts of the state. Since then, those populations and Michigan and Indiana populations have spread into our area. 

River otters have been confirmed in 75 Ohio watersheds. A limited and regulated trapping season was introduced state-wide in 2018-2019. 

Annual bridge surveys assess the distribution and population of river otters. Survey takers at 400 locations look for signs of otters such as slides and footprints, which are easier to see in snowy weather.

Sightings by the public can be reported to assist researchers. The ODNR's Wildlife Reporting System allows individuals to provide photographs or videos with latitude and longitude coordinates.

The purpose of this system is to report wildlife sightings for wildlife research purposes only. For all other wildlife-related questions, please contact 1-800-WILDLIFE (945-3543) (Mon.-Fri. 8 a.m. - 5 p.m.).
