Nooksack Transboundary Flood Initiative

Representatives from the State of Washington, the Province of British Columbia, local Tribes and First Nations, Whatcom County, and the City of Abbotsford have joined together to establish the Nooksack Transboundary Flood Initiative (NTFI) to better address repeated flooding events in the Nooksack and Sumas watersheds and the shared reliance on transboundary ecosystems and resources. The initiative aims to identify and pursue flood risk reduction and ecosystem restoration through:

  • Research and planning
  • Project review, coordination, and capital project support
  • Pursuit of funding
  • Communication
