The Little Miami River is a Class I tributary of the Ohio River that flows 105.5 miles (169.8 km) through five counties in southwestern Ohio in the United States. The Little Miami joins the Ohio River east of Cincinnati. It forms parts of the borders between Hamilton and Clermont Counties and between Hamilton and Warren Counties. The National Wild and Scenic River lends its name to the Little Miami Scenic Trail.

[edit] Hydrography

Watersheds of the Great Miami River (beige) and Little Miami River (yellow)

The Little Miami River is a tributary of the Ohio River. It is part of a watershed that drains a 1,757 square miles (4,550 km²) area in 11 southwestern Ohio counties: Clark, Montgomery, Madison, Greene, Warren, Butler, Clinton, Clermont, Brown, and Highland.^[4] The river discharges on average 1,737 cubic feet per second (49.2 m³/s) into the Ohio River each year.^[3] An average of 1,280 cubic feet per second (36 m³/s) flow through the river proper; after heavy rains, the river flow may rise to 84,100 cubic feet per second (2,380 m³/s).^[5]

Tributaries of the Little Miami include the East Fork, North Fork, Todd's Fork, Duck Creek, Caesar Creek, Massie Creek, and Turtle Creek. The river's main tributary, East Fork,^[6] was dammed in 1977 by the United States Army Corps of Engineers to create Harsha Lake, located in East Fork State Park. Similarly, in 1973, the Army Corps dammed Caesar Creek to create Caesar Creek Lake, located in Caesar Creek State Park.^[6]

The river's headwaters, considered part of the North Fork, are located about 5 miles (8.0 km) from South Charleston in Clark County,^[7] near Plattsburgh.^[2] The river empties into the Ohio River at California, a neighborhood of Cincinnati in Hamilton County.^[8] Between the headwaters and the mouth, there is a 705-foot (215 m) decrease in elevation.^[7]

[edit] History

The Little Miami river is named for the Miami, an Algonquian-speaking Native American people who lived in the region during the early days of white settlement. Historically, the river formed the eastern boundary of the Symmes Purchase and the western boundary of the Virginia Military District.

The 1968 Wild and Scenic River Act designated portions of the Little Miami National Scenic River as Ohio's first National Wild and Scenic River. On April 23 of following year, the Little Miami State Scenic River from Milford to the headwaters became Ohio's first State Scenic River, due to legislation that predated the the national act by a few months.^[9] The remainder of the river was added to the State Scenic River in 1971.^[10]

The former Peters Cartridge Company factory in Hamilton Township, which closed in 1944 and is now owned by DuPont, was declared a Superfund site in 1996, due to the factory's use for manufacturing gunpowder and ammunition. Since then, studies by the Ohio Environmental Protection Agency have established that the site no longer poses an environmental hazard to the nearby river.^[11]

[edit] Ecology

The Little Miami River is home to at least 87 species of fish, as well as many species of turtles, frogs, water snakes, birds, mammals and invertebrates. The river contains 36 species of mussels, including two threatened species, one of which is endangered. Ohio considers five of the species to be endangered.^[12] Recently, Zebra mussels and Asiatic clams have crowded out native species.

The river is protected by a number of nature preserves owned by Little Miami Inc., as well as by state and local parks (see below).^[13]

[edit] Recreation

The Little Miami River is a National Scenic River. A series of state and county parks and bike trails have been built along the river, primarily the Little Miami Scenic Trail, which is concurrent with the Buckeye Trail and Little Miami Scenic State Park. Most of these trails have been built along the abandoned rail grades that run along the river (see Rail trail). The Ohio to Erie Trail project, under construction, aims to link these trails to other trails statewide to create a single bike trail from Lake Erie to the Ohio River.

The Little Miami is also popular among canoers and anglers. There are several canoe liveries along its course and the smallmouth bass fishing in the river is among the best in the state. For a river its size and considering that it drains mainly agricultural land, the water quality of the Little Miami River is excellent. Visitors may see a variety of wildlife including several varieties of turtles, Mallards, and other ducks, Canadian Geese and Blue heron.
