BUFFALO RIVER WATERSHED (06040004) OF THE TENNESSEE RIVER BASIN WATERSHED WATER QUALITY MANAGEMENT PLAN TENNESSEE DEPARTMENT OF ENVIRONMENT AND CONSERVATION DIVISION OF WATER POLLUTION CONTROL WATERSHED MANAGEMENT SECTION Presented to the people of the Buffalo River Watershed by the Division of Water Pollution Control November 3, 2005. Prepared by the Columbia Environmental Field Office: Chad Augustin Tim Wilder, Manager The Nashville Environmental Field Office: James R.

Forty-eight rare plant and animal species The Watershed Approach recognizes awareness that have been documented in the watershed, to include restoring and maintaining our waters requires eleven rare fish species, three rare mussel species, crossing traditional barriers (point vs. nonpoint four rare snail species and one rare crustacean sources of pollution) when designing solutions. species. Portions of one stream in the Buffalo River These solutions increasingly rely on participation by Watershed is listed in the National Rivers Inventory both public and private sectors, where citizens, as having one or more outstanding natural or elected officials, and technical personnel all have cultural values and a portion of the Buffalo River opportunities to participate. The Watershed has also been designated as a State Scenic River.

Assessment data are based on the 2002 Water Quality Assessment of 1,200.0 miles in the watershed. Also in Chapter 3, a series of maps illustrate Overall Chapter 5 is entitled Water Quality Partnerships in Use Support in the watershed, as well as Use the Buffalo River Watershed and highlights Support for the individual uses of Fish and Aquatic partnerships between agencies and between Life Support, Recreation, Irrigation, and Livestock agencies and landowners that are essential to Watering and Wildlife. Another series of maps success. Programs of federal agencies (Natural illustrate streams that are listed for impairment by Resources Conservation Service, U.S. Fish and specific causes (pollutants) such as Nonpriority Wildlife Service, U.S. Geological Survey and Organics, Pathogens, Habitat Alteration and Tennessee Valley Authority), and state agencies Nutrient Enrichment.

Chapter 4 is organized by HUC-10 initiatives of active watershed organizations (Five subwatersheds. Maps illustrating the locations of Rivers RC & D Council) are also described. STORET monitoring sites and USGS stream gauging stations are presented in each Point and Nonpoint source approaches to water subwatershed. quality problems in the Buffalo River Watershed are addressed in Chapter 6. Chapter 6 also includes comments received during public meetings, along with an assessment of needs for the watershed. The full Buffalo River Watershed Water Quality Management Plan can be found at: http://www.state.tn.us/environment/wpc/watershed/wsmplans/ The Buffalo River Watershed is Composed of three USGS- Delineated Subwatersheds (10-Digit Subwatersheds). Point source contributions to the Buffalo River Watershed consist of seven individual NPDES- permitted facilities, two of which discharge into streams that have been listed on the 1998 303(d) list. Other point source permits in the watershed are Aquatic Resource Alteration Permits (22), Tennessee Multi-Sector Permits (7), Ready Mix Concrete Plant Permits (2) and Water Treatment Plant Permits (1). Agricultural operations include cattle, chicken, hog, and sheep farming. Maps illustrating the locations of NPDES and ARAP permit sites are presented in each subwatershed.

The lowest average 7 consecutive days flow with average recurrence frequency of once every 10 years. 303(d). The section of the federal Clean Water Act that requires a listing by states, territories, and authorized tribes of impaired waters, which do not meet the water quality standards that states, territories, and authorized tribes have set for them, even after point sources of pollution have installed the minimum required levels of pollution control technology. 305(b). The section of the federal Clean Water Act that requires EPA to assemble and submit a report to Congress on the condition of all water bodies across the Country as determined by a biennial collection of data and other information by States and Tribes. AFO. Animal Feeding Operation. Ambient Sites. Those sites established for long term instream monitoring of water quality. ARAP. Aquatic Resource Alteration Permit. Assessment. The result of an analysis of how well streams meet the water quality criteria assigned to them. Bankfull Discharge. The momentary maximum peak flow before a stream overflows its banks onto a floodplain. Basin. An area that drains several smaller watersheds to a common point. Most watersheds in Tennessee are part of the Cumberland, Mississippi, or Tennessee Basin (The Conasauga River and Barren River Watersheds are the exceptions). Benthic. Bottom dwelling. Biorecon. A qualitative multihabitat assessment of benthic macroinvertebrates that allows rapid screening of a large number of sites. A Biorecon is one tool used to recognize stream impairment as judged by species richness measures, emphasizing the presence or absence of indicator organisms without regard to relative abundance. BMP. An engineered structure or management activity, or combination of these, that eliminates or reduces an adverse environmental effect of a pollutant. 1 Glossary BOD. Biochemical Oxygen Demand. A measure of the amount of oxygen consumed in the biological processes that break down organic and inorganic matter. CAFO. Concentrated Animal Feeding Operation. Designated Uses. The part of Water Quality Standards that describes the uses of surface waters assigned by the Water Quality Control Board. All streams in Tennessee are designated for Recreation, Fish and Aquatic Life, Irrigation, and Livestock Watering and Wildlife. Additional designated uses for
