Fish Habitat Restoration

An oil and gas producer received an environmental compliance warning from the regulator for a watercourse crossing. The culvert, transferred during an asset acquisition, was improperly installed, leading to a 1.10 m elevation that obstructed fish passage on a Bull Trout spawning tributary.

Earthmaster quickly assessed the crossing and developed a rehabilitation plan. A hydrologic analysis guided the project, which required various regulatory approvals. Sedimentation was minimized during instream work, and the culvert was replaced. Earthmaster supervised the project, including planning, safety, construction, and fish habitat restoration.

The regulator was satisfied with the timely completion, and the client appreciated the efficient, on-budget work. Fish habitat was restored, and the LOC was returned to full operation. Annual inspections now ensure the crossing’s longevity.
