Black Creek Impairments

Black Creek is a coldwater designated water body that should support a trout population and the food sources they rely on.  Because of excessive sedimentation within the creek it cannot support a trout fishery.  Therefore, the creek appears on the federal Clean Water Act’s Section 303(d) “nonattainment” list.  

Federal Code requires the development of a plan to address water quality impairments by establishing allowable pollutant loading limits called total maximum daily loads, or TMDLs. The TMDL is based on the relationship between pollutant sources and in-stream water quality conditions. A TMDL provides a basis for determining the pollutant reduction necessary to restore the quality of the water resource. The purpose of the Black Creek TMDL is to identify appropriate actions to reduce sediment loading in the Watershed. Management practices to address sedimentation in Black Creek include:

  • Adequate storm water management
  • Vegetative buffer strips along the stream.
  • Channel stabilization measures.
  • Development of a flow-through filter marsh to capture about 20 square miles of agricultural runoff from the upper watershed.
  • Wetland protection and reclamation to reduce flash flooding to the stream, which scours creek banks and channels.
