The Calligan Creek Hydroelectric Project is a 6 MWe Pelton wheel run-of-the-river hydroelectric power station in Western Washington. It is operated by the Snohomish County Public Utility District on a tributary of the Snoqualmie River in King County, Washington, approximately east of Seattle. The power station has been operational since February 2018. As of year-end 2024, the project produces 17,156 MWh of power per year.
Construction involved building a wide, tall weir for the water not diverted through the turbine to flow over; a fish ladder; a penstock; a powerhouse; and of transmission line to interconnect with the grid.
