  Kratzer Run is a 5.75 mi (9.25 km)-long 3rd order tributary to Anderson Creek in Clearfield County, Pennsylvania. It is the only stream bearing this name in the United States.
  
  ## Geography and environmental issues
  
  Kratzer Run is the largest tributary to Anderson Creek and drains a region of farmland and places that have been surface mined for coal. As a result, Kratzer Run suffers from Acid Mine Drainage (AMD) and the impact of adjacent highways and communities is considered the most degraded tributary to Anderson Creek.
  
  Bilger Run, a tributary, is also impaired by AMD. Numerous places of erosion have been noted as well. In spite of the impacts, numerous efforts are underway to mitigate the pollution.
  
  ## Variant names
  
  According to the Geographic Names Information System, it has also been known historically as:
  
  * Little Anderson Run
  
  ## Course
  
  Kratzer Run rises about 1 mile southeast of Grampian, Pennsylvania, and then flows generally east to join Anderson Creek at Bridgeport.
  
  ## Watershed
  
  Kratzer Run drains 15.41 square miles (39.9 $km^2)$ of area, receives about 43.3 in/year of precipitation, has a wetness index of 368.63, and is about 63% forested.
