wild and scenic designated areas

The White Clay Creek Wild and Scenic Rivers System Act (P.L. 106-357) designated the following tributaries or river segments of White Clay Creek into the National Wild and Scenic Rivers System: White Clay Creek, from the confluence of the East and Middle Branches in London Britain Township, Pennsylvania, downstream to its confluence with the Christina River in New Castle County, Delaware; the East, West and Middle Branches within Pennsylvania; Middle Run and Pike and Mill Creeks in Delaware; and all other second-order streams as shown on the Designated Area Map. The following tributaries or river segments were found eligible but not suitable for federal Wild and Scenic River designation: Lamborn Run (along with the properties on which the intake structures and pipelines for the Thompson Station Reservoir will be located; Lamborn Run will remain unsuitable until such time as it is removed from the Delaware River Basin's Comprehensive Plan as a potential reservoir location); the East Branch from the point at which it enters New Garden Township at the Franklin Township line, approximately 10,500 feet, to the point at which it exits New Garden Township at the London Britain Township line; Egypt Run and its unnamed tributary; the East Branch within the Borough of Avondale, 500 feet north of the Borough of Avondale wastewater treatment facility and south of the Borough of Avondale wastewater treatment facility to the London Grove Township line; the Middle Branch within London Grove Township, 500 feet north and south of the Borough of West Grove wastewater treatment facility; and the properties on which are located the surface water intakes, water treatment and wastewater treatment facilities of the City of Newark and United Water Delaware and the Borough of West Grove and Avondale; Churchman's Marsh is deemed not suitable until such time as it is removed from the Delaware River Basin Commission's Comprehensive Plan as a potential reservoir location. (note: this area was expanded in 2014 with the passage of the White Clay Wild & Scenic Expansion Act)

The Management Planning Committee concluded that the inclusion of riparian corridors in the designated area is wise, as most of the issues raised in the White Clay Creek watershed involve the protection and restoration of those corridors for the benefit of wildlife and the enhancement of water quality. The White Clay Creek Wild and Scenic Rivers System Act (P.L. 106-357) defined the lateral boundaries as 250 feet from the ordinary high-water mark on both sides of all segments designated by the act.
