There are several small dams and reservoirs along the river, including the Boyer Chute National Wildlife Refuge, which contains a series of impoundments and wetlands used primarily for migratory bird habitat. The river also provides recreational opportunities such as fishing, boating, and camping. Agricultural uses of the Boyer River include crop irrigation and grazing. The Boyer River has a long and storied history, and its waters have played an important role in the development of western Iowa.
