Bilger Run rises about 2 miles southeast of Chestnut Grove, Pennsylvania, in an area of wetlands and then flows generally southeast to join Kratzer Run at Stronach. It runs through areas that have been surfaced mined for coal in its upper reaches.[3]
Watershed
Bilger Run drains 7.22 square miles (18.7 km2) of area, receives about 43.9 in/year of precipitation, has a wetness index of 407.40, and is about 68% forested.[5] Bilger Run is heavily loaded with metals from Acid Mine Drainage (AMD) and contributes a lot to the pollution load of Kratzer Run and then on into Anderson Creek. No fish were found at the sampling station on Bilger Run.[6]
Natural History
Bilger Run drains parts of the Anderson Creek Montgomery Creek LCA and is also the location of Bilger Rocks BDA. The LCA is noted for providing contiguous forested habitat for interior forest species, while the BDA provides habitat for a species of rare plant.[7]
