Best Management Practices (BMPs) can prevent or minimize the impact of forestry activities on rivers, lakes, streams, groundwater, wetlands, and visual quality.
Cross-drainage culverts let water that isn’t confined to a perennial or intermittent stream channel move from one side of the road to the other without crossing the surface. Proper use of cross-drainage culverts can improve water quality while allowing forest operations to continue.
Operators can place cross-drainage culverts at regular intervals along grades, below banked seepages, and where water will run directly onto log landings or forest roads and trails.
When installing cross-drainage culverts:
Typical upland cross-drainage culvert
Culverts move water from one side of the road or landing to the other without eroding surfaces.
Culverts are expensive to install and require frequent maintenance.
Keep culverts free of debris at all times. Otherwise, they will plug up and become ineffective. Adequately drain road grades during placement of culverts.
