Wises Mill Run is a steep first-order tributary to the main stem of the Wissahickon Creek. The tributary consists of a northern branch, which is 3,500 feet long, and a southern branch, which is 1,300 feet long. The two branches merge just north of Wises Mill Road and continue for another 1,900 feet before meeting the Wissahickon Creek. The stream channel is classified as a step-pool. The dominant substrate varies from bedrock to cobble-sized material. Both the valley floor and channel have been substantially impacted by past and current land use.
Beginning in May 2010, a streambank erosion management project will begin. Elements of the project include placing large woody debris and root wads along the base of the streambank, which will reduce the occurrence of erosion. The streambank and adjacent floodplain will be re-graded, and vegetation will be planted to establish a riparian buffer. The roots of the vegetation planted in the riparian buffer will help to hold the soil in place and prevent the soil from entering the stream, especially during storms.
