Homochitto River

The Homochitto River (pronounced "ho-muh-CHIT-uh") is a river in the U.S. State of Mississippi. It flows from its source in southwest Mississippi for about 90 miles (145 km) west and south, emptying into the Mississippi River between Natchez and Woodville.

According to one source, Homochitto is a Choctaw name likely meaning "big red".

The Homochitto River originates in several headwater tributaries along the border between Copiah County and Lincoln County. It flows west and then south through the Homochitto National Forest. After passing through Lincoln County the river enters Franklin County, still flowing generally south.

Just before McCall Creek joins from the east, the Homochitto is crossed by two bridges, one for U.S. Route 84 and one for the Illinois Central Railroad. Then the river begins to flow southwest, passing by the town of Bude. Below Bude the river is crossed by U.S. Route 98. Not far below that the river is joined by the Middle Fork Homochitto River, from the north. Several miles downriver from there, the river becomes the boundary between Franklin and Amite counties, at which point it begins to flow more directly westward. On the south side the border between Amite County and Wilkinson County is located just east of the town of Rosetta.

At Rosetta the river is crossed by two bridges, one for Mississippi Highway 33 and one for the Illinois Central Railroad. Still flowing westward, the river flows through a broad floodplain. Once highly meandering, it has been straightened and channelized to a degree. On the north side Franklin County changes to Adams County. Near the town of Doloroso the Homochitto River is crossed by U.S. Route 61.

Below Doloroso the river originally flowed south, then west, to join the Mississippi River at Lake Mary, an Oxbow Lake formerly part of the main Mississippi channel. Today most of the Homochitto's water flows instead west from Doloroso, through the Abernathy Channel created in 1938 by the United States Army Corps of Engineers. Via this route the Homochitto River enters the Mississippi River several miles north of Lake Mary.

In 1938 the United States Army Corps of Engineers began channelizing the river by building the Abernathy Channel, a cutoff running from the Homochitto River near Doloroso to the Mississippi River about 15 miles (24 km) upstream from where the Homochitto originally emptied into the Mississippi. This reduced the river's length below Doloroso from about 20 miles (32 km) of meandering distributaries to a 9 miles (14 km) relatively straight outlet. Additional cutoffs between Doloroso and Rosetta were constructed in 1940, reducing the river's channel by about 4 miles (6 km).

Other flood control projects on the lower Homochitto, completed in 1952, included the cleaning and desnagging of the main channel, as well as the excavation of more cutoffs. All these projects were for the purpose of flood control along the lower Homochitto River. They had unintended consequences, as engineers did not fully understand river dynamics when undertaking these projects.
