This plan represents a collaborative planning process undertaken in the Horsefly River watershed with a multi-partner planning team of individuals and groups passionate about the conservation and restoration of freshwater ecosystems and the species they support. Plan development was funded by the B.C. Salmon Restoration and Innovation Fund, Canada Nature Fund for Aquatic Species at Risk, and the RBC Bluewater Project. We were fortunate to benefit from the feedback, guidance, and wisdom of many groups and individuals who volunteered their time throughout this process — this publication would not have been possible without the engagement of our partners and the Planning Team (see Planning Team in Appendix B – Partners and Detailed Methods).

We recognize the incredible fish passage and connectivity work that has occurred in the Horsefly River watershed to date, and we are excited to continue partnering with local groups and organizations to build upon existing initiatives and provide a road map to push connectivity work forward over the next 20 years and beyond.

The Canadian Wildlife Federation recognizes that the lands and waters that form the basis of this plan are the traditional unceded territory of the Northern Secwepemc people. We are grateful for the opportunity to learn from the stewards of this land and work together to benefit Pacific salmon. A special thank you to Nishitha Singi for sharing the traditional Secwepemctsín names used in this plan.

Model outputs were refined based on feedback provided by local knowledge holders beyond the Planning Team. Accessibility models were inspired by fish-passage prioritization approaches developed by British Columbia’s Fish Passage Technical Working Group.
