# Understanding the Soo Locks Security and Economic Reporting Act of 2025

The Soo Locks in Michigan are a critical piece of American infrastructure that allow ships to travel between Lake Superior and the lower Great Lakes. This bill requires the federal government to study the security of these locks and figure out what would happen if they broke down or were attacked. Within one year, the Secretary of Transportation, working with the Coast Guard and Department of Defense, must submit a detailed report to Congress examining the current security setup, identifying any weak spots, and explaining what the economic fallout would be if the locks stopped working.

The report needs to address several key questions. First, it will identify security problems that currently exist at the locks. Second, it will analyze how a failure would ripple through the supply chain—meaning what products wouldn't get delivered, which industries would be hurt, and how it would affect both the local region and the entire country. Third, it will assess potential threats, whether from other countries or domestic sources. The report will also describe what the Coast Guard and other agencies are currently doing to protect the locks.

Finally, the bill asks for recommendations on how to make the locks more secure and how to reduce damage to American supply chains if something does go wrong. These recommendations must include cost estimates so Congress knows what improvements would actually cost. Essentially, this is a fact-finding mission to understand how vulnerable this critical infrastructure is and what we should do about it. The bill itself doesn't make any changes—it just orders the government to study the problem and report back with solutions.
