Sumas River Watershed Flood Mitigation Plan

The Sumas River Watershed Flood Mitigation Plan (SRWFMP) planning initiative is a collaborative effort between Indigenous governments, municipal governments and the provincial government to develop a plan that addresses flooding risks and restores ecosystems in the Sumas River Watershed. The involved parties recognize that safeguarding the Sumas Prairie and its vital communities, ecosystems, agriculture industry and critical infrastructure requires not only technical and infrastructural solutions, but also a steadfast commitment to honouring the many enduring ties of the Stó:lō Nations. By integrating these diverse perspectives and expertise, the SRWFMP aims to set a new benchmark for resilience—ensuring that flood risk mitigation is as comprehensive and dynamic as the challenges being faced.

We want to hear from you!
