CHAPTER IV: WILDLIFE HABITATS FOR MISSISSIPPI’S SGCN,

THREATS AND CONSSERVATION ACTIONS^207

12.5. Upper Coastal Plain,

Yazoo Drainage

„ Value to SGCN - 53

„ Rank - 10th of 18 Lotic and Lentic Systems

DESCRIPTION AND LOCATION
UEGCP
These streams are tributaries of the Yazoo River which
lie east of the Mississippi alluvial plain. Portions of the Tallahatchie, Yocona, Yalobusha and Coldwater
occur in this region, as well as many smaller tributaries of the Yazoo River. Many streams in this region
have been modified by channelization, construction of diversion canals, desnagging and construction of
flood control dams.

CONDITION AND CONSERVATION STATUS

Many streams in the upper Yazoo drainage have been channelized. Much of the
surrounding lands have been converted to agriculture. The four main tributaries
to the Yazoo River (Coldwater, Tallahatchie, Yocona and Yalobusha rivers)
have been impounded by flood control reservoirs.

The stream habitat that remains in this drainage is considered to be vulnerable
because of extensive alteration caused by channelization, agricultural use of
surrounding lands and impoundments.

12.5.a. Small streams. (see 12.2.a for definition).

12.5.b. Loess Hills Streams. These are small streams that are confined to the loess hills region

of Mississippi, and are tributaries of the Big Black, Yazoo or Mississippi rivers.

12.5.c. Medium streams. (see 12.2.b for definition).

12.5.d. Large Streams. (see 12.3.c for definition).
