Background - Spring Creek is a fertile, 22-mile long limestone stream that drains a 144 square mile watershed in Centre County, Pennsylvania. Spring Creek arises near Boalsburg and flows northeast through State College and Bellefonte to its confluence with Bald Eagle Creek in Milesburg. The watershed is geographically and geologically unique, characterized by a series of long, high ridges and broad limestone valleys. The Spring Creek watershed is home to a number of rare, threatened, or endangered plants and animals and also harbors one of the most productive wild trout fisheries in Pennsylvania. Significant groundwater input provides a stable source of cold, fertile water – ideal conditions for wild trout populations. Total brown trout biomass and the number of quality-size fish make it one of the best Class A wild trout streams in Pennsylvania and it is one of the few streams in the northeastern United States that support this caliber of wild trout fishery. However, the Spring Creek watershed is experiencing some of the most rapid growth and development in Pennsylvania, which has resulted in habitat loss and degradation due to increased stormwater runoff, sedimentation, and reduced riparian protection. In recognition of this important resource, the Pennsylvania Fish and Boat Commission (PFBC), in partnership with many other organizations (see list below), have undertaken several recent projects to protect, conserve, and enhance Spring Creek and its exceptional aquatic resources.
