The Turkey River is a 180-mile-long river located in northeastern Iowa. It was named after the wild turkeys that roamed the area. The river has played an important role in the area's history, serving as a transportation route for Native Americans and early settlers. The river's hydrology has been impacted by agricultural practices, causing increased sedimentation and nutrient pollution. Several reservoirs and dams have been constructed on the river, including the Martelle Dam and Backbone Lake. These provide recreational opportunities for fishing and boating. The river is also used for agricultural purposes, with many farms located along its banks. Despite these uses, conservation efforts have been put in place to protect the river's natural ecosystem, including riparian buffer zones and wetland restoration projects.
