THE SPRING CREEK WATERSHED ATLAS

Introduction The temperature of spring and stream water within the Spring Creek watershed in central Pennsylvania is important for many water uses, especially maintaining healthy aquatic ecosystems, water recreation and a highly-valued trout fishery. Trout are stressed when water temperatures exceed about 68.0 degrees Fahrenheit (°F) and temperatures above about 74.2 °F can be lethal. Many headwater mountain streams and springs emerge from the forested uplands with non-carb

Beginning in 1999 monitoring of stream and spring water quality was initiated by the Spring Creek Watershed Association to provide data to citizens, business leaders and public officials to better protect and manage water resources. The Water Resources Monitoring Project involves quarterly sampling of 15 stream sites and 8 springs mainly during low flows (see Figs. 1-2 for locations of and Table 1 for descriptions of monitoring sites). Monitoring is largely supported by loc
