The Wabash River (French: Ouabache) is a 503-mile-long (810 km)river in the Midwestern United States that flows southwest from near the Indiana border in northwest Ohio, across northern and central Indiana to southern Illinois, where it forms the Illinois-Indiana border before draining into the Ohio River, of which it is the largest northern tributary. From the dam near Huntington, Indiana, to its terminus at the Ohio River, the Wabash flows freely for 411 miles (661 km). Its watershed drains most of Indiana.
The Wabash is the state river of Indiana, and subject of the state song "On the Banks of the Wabash, Far Away" by Paul Dresser. Two counties (in Indiana and Illinois), eight townships in Illinois, Indiana, and Ohio; one Illinois precinct, one city, one town, two colleges, one high school, one canal, one former class I railroad, several bridges and avenues are all named for the river itself while four US Navy warships are either named for the river or the numerous battles that took place on or near it.
As the Laurentide ice sheet began to retreat from present day Northern Indiana and Northwest Ohio between 14,000 and 15,000 years ago, it receded into three distinct lobes. The eastern or Erie Lobe sat atop and behind the Fort Wayne Moraine. Meltwater from the glacier fed into two ice-marginal streams, which became the St. Joseph and St. Marys Rivers. Their combined discharge was probably the primary source of water for the proglacial Wabash River system.
As the Erie Lobe of the glacier continued to retreat its meltwater was temporarily trapped between the ice front to the east and the Fort Wayne Moraine to the west, and formed proglacial Lake Maumee, the ancestor of modern Lake Erie. Around 11,000 years ago the waters of Lake Maumee became deep enough that it breached a "sag" or weak spot in the Fort Wayne Moraine. This caused a catastrophic draining of the lake which in turn scoured a 1 to 2 mi (1.6 to 3.2 km) wide valley known as the Wabash-Erie Channel or "sluiceway". The Little (Wabash) River flows through this channel and U.S. 24 traverses it between Fort Wayne and Huntington. The valley is the largest topographical feature in Allen County, Indiana.
When the ice melted completely from the region, new outlets for Lake Maumee's water opened up at elevations lower than the Wabash-Erie Channel. While the St. Joseph and St. Marys Rivers continued to flow through the channel, Lake Maumee no longer did. Now a low-lying, probably marshy bit of terrain lay in between.
It is not known for certain when, but at some point in the distant past the St. Joseph and St. Marys Rivers jumped their banks and flooded the marshy ground of the Fort Wayne Outlet. The discharge of this unusual flood was enough to cut across the outlet and come into contact with the headwaters of the Maumee River. Once this happened, the flood waters rushed to the east into the Maumee River, and their erosive force was enough that the new channel cut across the Fort Wayne Outlet into the Maumee River was at a lower elevation than that of the sluiceway. This meant that when the flood waters receded, the sluiceway was permanently abandoned by the two rivers. As a result of capturing them both, the Maumee was converted from a minor creek to a large river. Once again, river waters flowed through the Fort Wayne Outlet, but now they flowed eastward, toward Lake Erie, instead of westward. Following this event, the branch of the Wabash River that originates along the Wabash Moraine near Bluffton became the system's main course and source.
For part of its course the Wabash follows the path of the pre-glacial Teays River.
The name "Wabash" is an English spelling of the French name for the river, "Ouabache". French traders named the river after the Miami-Illinois word for the river, waapaah?iiki, meaning "it shines white", "pure white", or "water over white stones". The Miami name reflected the clarity of the river in Huntington County, Indiana where the river bottom is limestone.
The Wabash was first mapped by French explorers to the Mississippi, including the sections now known as the Ohio River. Although the Wabash is today considered a tributary of the Ohio, the Ohio was considered a tributary of the Wabash until the mid-18th century. This is because the French traders traveled north and south from Canada to the Gulf of Mexico via the Wabash; it served as a vital trade route for North American-French trade.
The United States has fought five battles on or near the river: the Battle of Vincennes (1779), St. Clair's Defeat (1791), the Attack on Fort Recovery (1794), the Battle of Tippecanoe (1811), and the Siege of Fort Harrison (1812). Different conflicts have been referred to as the "Battle of the Wabash". A 329-acre (133 ha) remnant of the old-growth forests that once bordered the Wabash can be found at Beall Woods State Park, near Mount Carmel, Illinois. In the 19th century, the Wabash and Erie Canal, one of the longest canals in the world, was built along much the river. Portions are still accessible in modern times, but most of the abandoned canal no longer exists.
The Wabash River between Terre Haute and the Ohio River was navigable by large ships during much of the 19th century, and was a regular stop for steamships. By the late 19th century, erosion due to farming and runoff made the Wabash impassable to such ships. Dredging could have resolved the problem, but was not undertaken because railroads had become the preferred form of transport. The 200 mile stretch south of Terre Haute includes several inoperable swing bridges.
The river has shifted course several times along the Indiana and Illinois border, creating cutoffs where parts of the river are entirely in either Indiana or Illinois. However, both states generally regard the middle of the river as the state border.
For nine years in the 1920s, the Grand Rapids Hotel and resort was situated in Wabash County, Illinois, near the Grand Rapids Dam on the Wabash River. The owner was Frederick Hinde Zimmerman. The hotel drew its clientele from all over the United States.
Between the start of the river and Fort Recovery, the current is swift and the water remains very shallow and follows a poorly defined channel. The depth and low bridge clearances make the section nearly impassable by boat except in the most ideal conditions. At mile seven and mile nine, two tributaries give the river a significant boost in volume and at mile eleven the river flows past Fort Recovery. Two more tributaries add to the river's volume between Fort Recovery and Macedon at mile eighteen, making the river navigable for the remainder of its course. The river continues to flow northward passing the community of Wabash at mile twenty-three and then cutting sharply west, crossing into Indiana at mile twenty-eight.
Upon entering Indiana, there are many sharp turns in the river that frequently lead to log jams that can block the river. Because of the many turns in the river, the state created several separate canal channels to shorten the journey between the state line and Fort Wayne as part of the Wabash and Erie Canal project during the 1830s. The subsequent abandonment of the canals allowed the river to shift courses several times resulting in the formation of many cut-offs and coves with no outlet, giving the river a maze-like quality in the first seventeen-mile (27 km) stretch as it enters Indiana.
At mile forty-five, the river becomes straighter with few sharp bends. An additional seventeen tributaries raise the depth of the river considerably making it navigable for larger vessels. At mile fifty-nine, the river passes through Ouabache State Park where it begins to widen and become more shallow. The white limestone river bottom can sometimes be seen in the area, whereas it is not visible due to pollution elsewhere downstream. As the river exits the park and flows towards the city of Bluffton near mile sixty-six, it widens further, becoming more shallow; only a narrow channel is navigable by larger vessels. The river remains shallow and somewhat rocky with minor rapids until mile seventy-one near the community of Murray. There the river becomes calm and deeper until mile eighty-one due to the dam and levee at the town of Markle. The lock that was formerly at the site is abandoned and a narrow washout is the only means to bypass the dam. In the rocky washout the river level drops four feet, making it one of the most dangerous points on the river. Boaters are advised exit the river and reembark on the other side of the dam rather than traverse the washout.
At mile eighty-nine, the large Huntington Dam blocks the river. Built by the Army Corps of Engineers to make a reservoir, the dam creates the J. Edward Roush Lake. The lake is surrounded by park land and recreation areas and is about five miles (8 km) in length and a mile wide at its widest point. The mile-long stretch after the Huntington Dam is rarely navigable. No lock connects the two sections of the river, and the water is often very shallow. A second smaller dam at mile ninety-one presents a dangerous hazard, leading the section between it and the Huntington Dam to be closed to boaters.
At mile ninety-three the river is joined by its first major tributary, the Little River. The city of Huntington sits at the confluence of the two rivers. The tributary dramatically increases the volume of water in the Wabash at this point, and because of the dams on the Wabash, it often carries more water than the Wabash. Additional minor tributaries raise the water level between Huntington and the city of Wabash. As the river passes Wabash and moved towards Peru, it splits creating a series of islands; sandbars are common in the stretch. The river joins back into a single channel at Peru, and flows through one of its most gentle stretches until reaching Logansport where the river again splits into multiple channels with islands dividing them. Some of the channels are narrow and rocky, while the larger channels are navigable. Between Logansport and Delphi, at mile 176, is one of the few remaining stretches of the Wabash and Erie canal. It can be accessed at Delphi. Just past Delphi, the Wabash's second major tributary, the Tippecanoe River, joins the river. The confluence of the two rivers is part of Prophetstown State Park, the site of the 1811 Battle of Tippecanoe. The joining of the Tippecanoe raises the level of the Wabash dramatically. At this point, most large power boats can easily navigate the river at cruising speed.
The river passes the city of Lafayette at mile 210 and gradually begins to end its westward flow, beginning a wide turn to the south. At mile 241, at the city of Covington, the river begins flowing due south. The river is deep at this point, but there are several gravel bars between Covington and Terre Haute. Terre Haute, beginning at mile 300, is among the largest cities in Indiana. Although navigable by large ships in the past, the remainder of the river becomes shallow in places due to erosion and silt. The river gradually widens moving south. It borders Illinois beginning at mile 316, and serves as a state boundary line with Indiana for the remainder of its course.
At Darwin, a farmer's cooperative operates the Wabash's only ferry service. It is used to take heavy farm equipment across the river. South of Darwin, beginning at mile 410 a large bluff gradually rises, eventually towering two-hundred feet over the river. The area is one of the most remote through with the river, and it generally open land. The area becomes populous again as it nears the city of Vincennes at mile 441. Founded by the French about 1720, Vincennes is the oldest settlement in Indiana, and among the oldest in the American Midwest. The city is sited on a strategic bend in the river which allowed it to control river traffic. Four miles west, as the river turns southward, the river's second largest tributary, the Embarras River joins.
Past Vincennes, the Wabash is joined by its largest tributary, the White River at Mount Carmel, Illinois, significantly increasing its size, to over 750 feet wide. Roughly a mile downstream, near the Gibson Generating Station, another large tributary, the Patoka River also joins. During low water, there are rapids at the confluence, caused by an old canal lock that was abandoned after flooding. Further downstream, the river zig-zags, creating the "tail" of Gibson County, a panhandle between the river and Posey County. From the tail southward there are several cut-offs from the river, resulting in several natural exclaves between Indiana and Illinois, the largest of which is at Grayville. A flood caused the river to change course, disconnecting a two-mile (3 km) long stretch of the river and creating a lake entirely on the Illinois side. Between these exclaves is the historic town of New Harmony, a settlement created by utopians during the 1810s. where it is joined by the Black River on the Indiana side.
At mile 460, the river again splits into several channels. The area features sandy beaches and the largest islands in the river, some a mile in length. The Little Wabash River, the second-largest left tributary, joins at mile 482 on the Illinois side, near New Haven, Illinois. At mile 491 the Wabash drains into the Ohio River near Hovey Lake.

The major tributaries of the Wabash River include:
The Wabash River supports an abundant and diverse wildlife population. At least 150 species of birds have been sighted around the river. The waterfowl are most dependent on the river. Black-crowned and Yellow-crowned night heron, and merlin inhabit the area. Several species of shorebirds build nest on or near the banks of the river. The river is home to many species of fish including species of bass, sunfish, crappie, catfish, carp, and others. Aquatic reptiles including snakes and turtles also occur in the river. A number of amphibians occur throughout the river's watershed including the American bullfrog and the eastern newt. Crayfish are also common throughout the river.
