Yazoo River Basin

The Yazoo River Basin, Mississippi’s largest basin, drains an area of about 13,355 square miles. The basin covers all or parts of 30 counties and is about 200 miles in length and up to 100 miles in width in its northern half. Major streams include the Yazoo, Tallahatchie, Yalobusha, Coldwater, Bogue Phalia, Yocona, and Sunflower Rivers. Four major flood control reservoirs are also located in the basin - Arkabutla, Enid, Sardis, and Grenada. The outlet for the basin is the Mississippi River at the confluence of the Yazoo River north of Vicksburg.

Mississippi Delta Nutrient Reduction Strategy
The Mississippi Delta nutrient reduction strategy development process began with a visioning exercise with key partners and stakeholders to ensure a consistent approach, promote leveraging of resources, and foster stakeholder buy-in. A planning team, composed of multiple governmental agencies, non-profit organizations, academia, and agricultural producers, provided the direction for this effort. Eleven Work Groups formulated the details for 11 strategic elements: 1) Stakeholder awareness, outreach and education; 2) Watershed characterization: 3) Current status and historical trends; 4) Analytical tools; 5) Water management; 6) Input management; 7) Best management practices; 8) Point source treatment; 9) Monitoring; 10) Economic incentives and funding sources; and 11) Information management
Approved Total Maximum Daily Load (TMDL) Reports
Each impaired water body will have a report completed for each pollutant causing impairment. Each TMDL report includes the suspected sources of impairment, and predicts a reduction of the pollutant necessary to restore the water body to its intended use. For more information about the TMDL program, please click on the TMDL Quick Link.
Water Quality Assessment Report- Section 305(b) Report
MDEQ monitors the quality of surface water throughout the state. Monitoring data and information are used to make water quality assessments. Assessments are general characterizations of water body health. The state's most comprehensive assessment report is the Federal Clean Water Act Section 305(b) Water Quality Inventory Report. For more information about the 305(b) report and the water assessment process, please go to the Assessment Section Quick Link. The most recent 305(b) report with assessment information for this basin can be found at the link below:
Water Quality Impairments- Section 303(d) List
The Section 303(d) List of Water Bodies lists the impaired segments of specific water bodies, the location and length impaired, the cause of impairment, and the intended use.
Water Quality Standards
Surface waters (e.g., streams, rivers, lakes, estuaries, etc) are assigned intended uses. These designations allow regulatory agencies to establish water quality goals, which protect aquatic life and allow safe use by the public. These goals are referred to as Water Quality Standards. The designations that exist in Mississippi are Public Water Supply, Shellfish Harvesting, Recreation, and Fish and Wildlife (i.e., Aquatic Life Use Support). Click the link below for a map or a list of the designated waters of the Yazoo River Basin.
The Basin Management Approach, TMDLs, Assessments, and Standards Sections are all part of the Surface Water Division of MDEQ. For more information about activities relating to surface water, please visit the link to the Surface Water Division Home Page.
