Summary

The Secretary may start emergency work to fix problems that stop commercial boats on federal inland waterways or on nearby bypass routes. The Secretary can first decide an emergency exists after talking with the District Commanders who maintain the waterways, the waterway users, and the Coast Guard. Projects depend on available funding and must follow federal rules. Work must begin within 60 days of that decision and, when possible, be finished within 1 year. Up to $25,000,000 is authorized for each of fiscal years 2022 through 2024, available until spent. Bypass — an alternate water route next to a lock and dam used for commercial navigation during high water. Emergency condition — unsafe water levels or flows, obstructions like silt or rock, a damaged or unusable lock and dam, or any other situation the Secretary finds appropriate.
