Hayward Creek watershed is associated the Falls River reservoir and Big Falls hydroelectric project, and it has been identified as a sub-basin requiring priority actions (FWCP 2017). Our study has been designed to address priority action FLS.RLR.RI.10.01 – to conduct a habitat assessment and an assessment of fish passage in the Hayward watershed (Priority Type 3) (FWCP 2017). This action aims to determine if anadromous fish access is or was historically possible via the Hayward Lake (Ecstall River system) through to Falls Reservoir. This is a project under the Fish and Wildlife Compensation Program.
