The Maumee River (pronounced //) (Shawnee: Hotaawathiipi ) is a river in northwestern Ohio and northeastern Indiana in the United States. It is formed at Fort Wayne, Indiana by the confluence of the St. Joseph and St. Marys rivers, and meanders northeastwardly for 137 miles (220 km) through an agricultural region of glacial moraines before flowing into the Maumee Bay of Lake Erie at the city of Toledo, Ohio. It was designated an Ohio State Scenic River on July 18, 1974. The Maumee watershed is Ohio’s breadbasket, two-thirds farmland, mostly corn and soybeans. By 2012, agricultural practices along the Maumee River were responsible for phosphate levels in Lake Erie that cause yearly, deadly algae blooms in the lake, which in turn greatly threaten the lake's ecosystem. The Maumee supplies only about 5 percent of Erie’s water, but half its phosphorus. And while algae struggle to digest ordinary phosphorus — only about 30 percent gets taken up — fertilizer phosphorus is designed for plants to use instantly.
Historically the river was also known as the "Miami" in United States treaties with Native Americans. As early as 1671, French colonists called the river was called Miami du Lac, or Miami of the Lake (in contrast to the "Miami of the Ohio" or the Great Miami River). Maumee is an anglicized spelling of the Ottawa name for the Miami Indians, Maamii.
The Battle of Fallen Timbers, the final battle of the Northwest Indian War, was fought 3/4 mile (1.2 km) north of the banks of the Maumee River. After this decisive victory for General Anthony Wayne, Native Americans ceded a twelve mile square tract around Perrysburg and Maumee to the United States by the Treaty of Greenville in 1795. Lands north of the river and downstream of Defiance were ceded in 1807, and the rest of the Maumee River valley was ceded in 1817.
Prior to the development of canals, portages between the rivers were important trade routes. US forces built forts such as Fort Loramie, Fort Recovery, and Fort Defiance. In honor of General Wayne's victory on the banks of the Maumee, the primary bridge crossing the river near downtown Toledo is named the Anthony Wayne Suspension Bridge.
Natural history 
The Maumee River watershed was once part of the Great Black Swamp, a remnant of Glacial Lake Maumee, the proglacial ancestor of Lake Erie.. The 1,500 square mile swamp was a vast network of forests, wetlands, and grasslands. During the nineteenth century, settlers struggled to drain the swamp and to convert the land to farmland.
The mouth of the river at Lake Erie is wide and supports considerable commercial traffic, including oil, grain, and coal. However, about 12 miles (19 km) upstream, in the town of Perrysburg, Ohio, the river becomes much shallower and supports only recreational navigation above that point. The abandoned Miami and Erie Canal paralleled the Maumee between Defiance, Ohio and Toledo; portions of its towpath are currently maintained for recreational use. The Wabash and Erie Canal continued on from Defiance to Fort Wayne, crossing the "summit" to the Wabash River valley. Both were important pre-railway transportation methods in the 1840-60 period. The Miami and Erie was north of the river, until it crossed an aqueduct and turned south at Defiance, headed for Cincinnati. The Wabash canal was south of the Maumee until it reached Fort Wayne.
The Maumee has the largest watershed of any Great Lakes riverwith 8,316 square miles (21,540 km2). Its watershed includes a portion of southern Michigan. In addition to its source tributaries the St. Joseph and St. Marys rivers, the Maumee's principal tributaries are the Auglaize River and the Tiffin River, which join it at Defiance from the south and north, respectively.

Walleye run 
According to the Ohio Department of Natural Resources, the annual walleye run up the Maumee River is one of the largest migrations of riverbound walleyes east of the Mississippi. The migration of the walleye normally starts in early March and runs through the end of April. Although the first week of April is "historically" the peak of the migration, it varies according to environmental conditions. When river flows rise due to snow melt-off and the river water temperature reaches 40 - 50 degrees Fahrenheit, the migration begins. Walleye come to spawn from the western end of Lake Erie, and the Detroit River and Lake St. Clair in Michigan. The most popular method of fishing for the migrating walleye is by wading out into the river and casting.
