The Maple River flows through Barnes, Cass, Ransom, and Steele Counties in eastern North Dakota before joining the Sheyenne River, one of the major tributaries of the Red River of the North. As part of the larger Sheyenne River system, which harbors about 53 fish species—roughly twice the number found in other Red River tributaries—the Maple River benefits from this rich aquatic biodiversity. The river supports a variety of native and introduced species, making it an accessible option for anglers seeking diverse fishing opportunities in North Dakota's prairie landscape. While less prominent than some of the state's larger fisheries, the Maple River provides year-round fishing opportunities with no closed seasons for most species.
