Because of the accelerated schedule required by the consent decree, many of these TMDLs have been prepared out of sequence with the State’s rotating basin approach. The implementation of the TMDLs contained herein will be prioritized within Mississippi’s rotating basin approach. The amount and quality of the data on which this report is based are limited. As additional information becomes available, the TMDLs may be updated. Such additional information may include water quality and quantity data, changes in pollutant loadings, or changes in landuse within the watershed.

These histories documented the earliest set- tlement of the county as well as the events that shaped its history such as natu- ral disasters, political events, crimes, Civil War events, and its prominent citi- zens and organizations. Among those county histories was a combined volume titled “Biographical and Historical Memoirs of Eastern Arkansas”.

The report contains one or more Total Maximum Daily Loads (TMDLs) for water body segments found on Mississippi’s 1996 Section 303(d) List of Impaired Waterbodies. Because of the accelerated schedule required by the consent decree, many of these TMDLs have been prepared out of sequence with the State’s rotating basin approach.

    CANEBRAKE AND BOTTOMLAND HARDWOOD FOREST HABITAT RESTORATION AT BENSON CREEK NATURAL AREA Project Summary: This project addresses the need for habitat management to increase quality of bottomland hardwood forest and canebrake habitat in the Mississippi Alluvial Valley of eastern Arkansas. The objectives of this project are to increase the quality of bottomland hardwood habitat, expand existing cane stands within forests, and prioritize old field sites for restoration and restore cane to selected areas within those sites. Habitat restoration will benefit a variety of wildlife species, including many species of conservation concern.

Completion of the project will take two years. ECOREGION WHERE PROJECT WILL BE CONDUCTED The project presented in this preproposal will be conducted in the MAV ecoregion, specifically at Benson Creek Natural Area (BCNA) located in Monroe County, Arkansas.

White, and Members of the Geological Commission Gentlemen: Yalobusha County, in the north central part of Mississippi includes parts of two major physiographic provinces, the North Central Hills and the Bluff hills. The larger features of the topography are wide al luvial valleys and low rolling to rugged hills. The county is part of the Yazoo Drainage Basin. Dams now under construction across the Yocona and Yalobusha Rivers will, when completed, back the water up and flood some of the most fertile land of the county.
