Ohio has 3 designated Wild and Scenic Rivers covering 190.2 miles across 15 segments, all administered by the National Park Service. The Little Miami, Big and Little Darby Creeks, and Little Beaver Creek together protect some of the most ecologically significant river corridors in the Midwest — corridors recognized for exceptional biodiversity, native mussel fauna, and water quality that is rare among highly agricultural and urbanized states. All segments carry Scenic or Recreational classifications. Click any segment on the map below for details on each river’s protected reaches.
Wild and Scenic Rivers in Ohio at a Glance
Ohio’s three designated Wild and Scenic rivers reflect the conservation priority placed on protecting exceptional stream quality in one of the most intensively farmed and densely populated states in the eastern US. The Little Miami, flowing from near Springfield south to the Ohio River near Cincinnati, was among the earlier eastern designations and is today one of the longest protected river corridors in Ohio. The Big and Little Darby Creeks near Columbus protect a stream system recognized by The Nature Conservancy as one of the most biologically diverse streams in the Midwest, harboring one of the highest concentrations of native freshwater mussels in the nation. Little Beaver Creek in northeastern Ohio protects a forested Appalachian Plateau stream in Columbiana County known for exceptional clarity and native mussel diversity.
Classification Breakdown
Ohio’s WSR corridors carry no Wild segments — all three rivers have adjacent road and trail access and some shoreline development, placing them firmly in the Scenic and Recreational tiers. The Scenic classification dominates, reflecting the rivers’ largely undeveloped banks despite their proximity to population centers.
| Classification | Segments | Protected Miles |
|---|---|---|
| Scenic | 12 | 121.1 |
| Recreational | 3 | 69.1 |
Managing Agencies
The National Park Service administers all 15 segments through river management plans developed in partnership with Ohio DNR, county park districts, and the Nature Conservancy. The NPS does not maintain large developed infrastructure on these rivers but plays a coordinating role in conservation planning and shoreline protection.
| Agency | Segments | Miles |

Longest Designated Rivers in Ohio
| River | Miles | Segments | Classification | Agency |

| Little Beaver Creek Wild and Scenic River | 28.9 | 4 | Scenic | NPS |
The Little Miami is the most visited of Ohio’s designated rivers, partly because the Little Miami Scenic Trail — a rail-trail running along its east bank — passes through or near its entire designated length. The river is a classic Ohio canoe run from Yellow Springs south, with Class I-II riffles, limestone bluffs, and cedar glades in its upper reaches. The Big and Little Darby Creeks outside Columbus are recognized by conservation biologists as the most species-rich stream system in Ohio: the Darby Creek watershed harbors around 100 native fish species and 35 mussel species, including several federally listed as threatened or endangered. Little Beaver Creek in Columbiana County flows through forested Appalachian plateau terrain and is prized by local fly anglers for its smallmouth bass and occasional native brook trout in its headwaters.
Where to Run, Hike, or Fish Ohio’s Wild and Scenic Rivers
For paddling and floating
The Little Miami between Yellow Springs and Waynesville is Ohio’s most popular canoe run, with multiple commercial outfitters operating on the river from April through October. The upper reach has quick Class I-II riffles and the lower reach is broad flatwater suitable for families. The Big Darby is paddleable in spring but drops low by midsummer; access is through Madison and Union county parks. Little Beaver Creek offers a wilder flatwater float through forested terrain, with access managed by Ohio DNR and Beaver Creek State Park.
For native fish
Ohio’s designated rivers are among the most significant freshwater biodiversity sites in the eastern US. The Big and Little Darby Creek corridor is a national priority for mussel and fish conservation — Ohio DNR and The Nature Conservancy actively monitor recovery of the snuffbox mussel, the rayed bean, and the clubshell, all federally listed. The Little Miami holds one of Ohio’s few self-sustaining wild steelhead runs in its lower reaches, as well as strong populations of smallmouth bass throughout the designated corridor. Little Beaver Creek has historically been one of the cleanest streams in eastern Ohio and supports diverse native sunfish and darter communities. Fishing access is available at numerous county and state park pull-offs along all three rivers.
Maps for Neighboring States
Ohio’s designated rivers connect ecologically to systems in surrounding states. Pennsylvania to the east has significant WSR mileage including the Allegheny and Delaware. Michigan to the north holds 15 USFS-administered rivers. Kentucky to the south has the Red River. West Virginia has the Bluestone River. Indiana has no federally designated Wild and Scenic rivers.
