Three levels of thermal loading of Hyco Lake by heat from two steam-electric generators have resulted in higher temperatures and increased evaporation in the 3,750-acre (1,518 square hectometer) lake. During the winter, local temperature increases of 34°F (19°C) were sometimes observed at the surface as heated water spread out on top of the cooler, more-dense, lake water, affecting areas as large

Wastes entering the Yadkin River from the Winston-Salem area, particularly during heavy rains, resulted in several major fish kills in the late 1960's and early 1970's. The actions undertaken to solve this problem, included the collection of data on the time of travel and dispersion characteristics of the tributaries draining the Winston-Salem area and of the main stem of the Yadkin below their co

Water from a brackish-water zone (1,050-1,350 ft) has concentrations as high as 2,150 milligrams per liter chloride, and concentrations are suspected to be higher than 3,000 milligrams per liter chloride. This brackish water has been identified as the source of the water that contaminates the upper and lower fresh-water-bearing zones of the principal artesian aquifer. The confining unit separating

The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch (1973) recently completed a detailed investigation of the geology and morphology of
