Homeland Security Information Network Dams Portal

The Homeland Security Information Network-Critical Sectors (HSIN-CS), Dams Sector Portal  is an information-sharing network that provides situational awareness and allows sector partners to effectively collect and disseminate information among federal, state, and local agencies, and the private sector. It forms an important part of the Dams Sector information-sharing environment (ISE), providing a forum for members to access sensitive but unclassified information relevant to sector-specific issues.

Resources include various communities of interest, a reference library, capabilities for suspicious activity reporting, and access to training modules. The portal is managed by the Dams Sector-Specific Agency (SSA) in the Office of Infrastructure Protection.


The level of participation in the HSIN-CS Dams Portal is directly related to the structure of the Dams Sector ISE.

  • Level II Trusted Agent: Secondary or alternate representatives.
