Mt. Vesuvius Culvert & Check Dam
Each time Trail Creek Road was graded, large amounts of road base fines, which included mine waste, were pushed into the culvert. These fines were then transported to Clear Creek. The upper end of the culvert was extended placing the flared end section further away from the edge of the driving surface, thereby reducing fines loading to the culvert. Riprap check dams were constructed above the Mt. Vesuvius Lode culvert to provide energy dissipation above the culvert entrance. A trash rack was constructed to prevent large debris from blocking the culvert.
Based on the site hydrologic engineering goals were:
- to capture Total Suspended Solids (TSS), which should also serve to reduce metals loadings to Clear Creek; and
- improve the performance of existing hydraulic structures (culverts).
