Dams Sector Waterside Barriers Guide

The Dams Sector Waterside Barriers Guide, published by CISA, provides dam owners and operators with guidance on using waterside barriers to protect critical infrastructure from water-based threats such as swimmers, explosive-laden boats, and submerged devices. It outlines how to assess risk, integrate barriers into a broader security plan, and choose between barrier systems and technologies based on site-specific needs. Drawing lessons from both historical attacks and defense strategies, the guide emphasizes detection, delay, and interdiction capabilities, as well as the importance of proper maintenance. It serves as a comprehensive resource for strengthening physical security in the Dams Sector.
