Summary

Mine features in the Trail Creek watershed include draining mine adits, mine waste piles, and mill tailings. The Best Management Practices (BMP) construction design for the Centurion Pond and Culvert was formulated to enhance pre-existing conditions in this very narrow and steep creek by creating wet detention basins and energy dissipation structures to capture waste metal pollutants and prevent further erosion of the stream channel. An existing culvert was used as the outlet for a sediment trap and extension of this culvert to reduce fines loading to the creek.

Based on the site hydrologic engineering goals were:

  1. to capture Total Suspended Solids (TSS), which should also serve to reduce metals loadings to Clear Creek; and
  2. improve the performance of existing hydraulic structures (culverts).
