Sunflower River

The Sunflower River (also known as the Big Sunflower River) is one of the main tributaries of the Yazoo River in the U.S. state of Mississippi. It is navigable by barge for 50 miles. It rises in De Soto County, Mississippi near the Tennessee border and flows south for 100 miles to the Yazoo River. At Clarksdale on its banks, the annual Sunflower River Blues and Gospel festival is held.

The United States Army Corps of Engineers maintains a navigation channel, thirty miles in length. Built in 1976, the channel is used by barges and pleasure craft.

According to the USGS, variant names include Hushpuckaman Creek. The Hushpuckena River drains the northwestern part of the Sunflower River Basin, Quiver River drains the northeastern portion, and Bogue Phalia drains the west central portion of the watershed, all of which lies in the Mississippi River alluvium soil of the Yazoo Delta.

Water Quality

Like the Yazoo, this river is heavily silt laden. The river gets its mud from the bayous and small streams that feed it. The river has a distinct "Clear-Mud Line" where it meets the Yazoo, showing that the Big Sunflower is muddier than the Yazoo.
