The LeTort Regional Authority (LRA) was created in 1974 as an organization that would protect the valuable natural resource of the LeTort Spring Run. The LeTort Spring Run has been referred to as the “shrine of American fly-fishing,” and an “internationally famous trout stream” that traverses through four central Pennsylvania municipalities. Designated a Pennsylvania Scenic River in 1988, the LeTort Spring Run not only contributes to the scenic beauty of the area and provides recreational opportunities but also serves as a natural regulator of stormwater and flooding. Currently, the governments of Cumberland County, the Borough of Carlisle and North Middleton, South Middleton and Middlesex Townships serve as supporting governmental entities to the LeTort Regional Authority (LRA). The mission of the LeTort Regional Authority is to protect and preserve the LeTort Spring Run and its watershed by promoting flood control and developing access and recreational opportunities within the watershed. Goals include the minimization of flooding, improvement of pollutants, the protection and restoration of the natural conditions and amenities of the watershed, and the provision for public involvement and education regarding the use and understanding of the watershed’s resources.
