Meriwether, Cam Elliott, Dennis B. George, and V. Dean Adams. "The Duck River Utility Commission (DRUC) draws water from Normandy Reservoir and provides approximately 4 MGD of finished water to the cities of Tullahoma and Manchester, Tennessee. Due to a history of water quality complaints, an investigation of the DRUC water treatment system was initiated.
"During the first half of the year, the water contains alkalinity and calcium concentrations of 25 to 35 mg-CaCo3/L. As a result, the water treated by the plant is moderately corrosive. Corrosivity of the finished water is aggravated by high chlorine levels in the distribution system. Lime application, in conjunction with the addition of CO2 and soda ash, was evaluated for stabilization of the DRUC product water.
"During late summer, reducing conditions in the reservoir cause solubilization of iron and manganese which are transported to the middle water intake. Potassium permanganate treatment reduces iron below the recommended level of 0.30 mg/L; however, manganese in the finished water is frequently greater than the recommended 0.05 mg/L standard. Failure of the plant to properly treat manganese was due, in part, to inadequate determination of manganese in the laboratory. The P.A.N. low-range manganese test was evaluated and implemented in the DRUC lab."

"National Briefing--South Tennessee: State Receives Land." "The Tennessee Valley Authority donated to the state a 13,000-acre tract that includes one of North America's most biologically diverse rivers. The land along the Duck River was to have been used for the Columbia Dam project, which was scrapped in 1983 because of concerns about its environmental and budget consequences. The Duck River is home to 13 endangered fish and mussel species. It contains more fish species than all of Europe."

Wolfe, W.J., J.P. Evans, Sarah McCarthy, W.S. Gain, and B.A. Bryan. Tree Regeneration and Mortality Patterns and Hydrologic Change in a Forested Karst Wetland Sinking Pond, Arnold Air Force Base, Tennessee. "Multiple lines of evidence point to climate change as the driving factor suppressing tree regeneration since 1970 in Sinking Pond, a 35-hectare seasonally flooded karst depression located on Arnold Air Force Base near Manchester, Tennessee. Annual censuses of 162-193 seedling plots from 1997 through 2001 demonstrate that the critical stage for tree survival is the transition from seedling to sapling and that this transition is limited to shallow (less than 0.5 meters) ponding depths. Recruitment of saplings to the small adult class also was restricted shallow areas...Results of hydrologic modeling, based on rainfall and temperature records covering the period January 1854 through September 2002, show ponding durations after 197 considerably longer than historical norms, across ponding-depth classes. This increase in ponding duration corresponds closely with similar increases documented in published analyses of streamflow and precipitation in the eastern United States and with the suppression of tree regeneration at ponding depths greater than 0.5 meter indicated by tree-ring analysis. Comparison of the simulated stage record for Sinking Pond with the ages and elevations of sampled trees shows that prolonged (200 days or more per year) inundation in more than 2 of the first 5 years after germination is inversely related to successful tree recruitment and that such inundation was rare before 1970 and common afterwards."
