The hydro power project, located in the Sultan River Basin, provides nearly 4% of the PUD’s power needs and 80% of Snohomish County’s water supply.
LIHI certifies dams that have not been recommended for removal.
They must adequately protect or mitigate their impacts in eight key resource areas: river flows; water quality; fish passage and protection; watersheds; threatened and endangered species; cultural resources; public access; and recreational opportunities.
PUD general manager Steve Klein said the Jackson project is an invaluable community resource that is clean, renewable and reliable.
"PUD focused on operating the facility in a manner that protects the natural environment while serving the community’s needs for a high quality water and energy supply," Klein said.
The PUD recently received a new 45-year license for its Jackson Hydroelectric project.
Under the new license, issued by the Federal Energy Regulatory Commission, the project will continue to implement a range of environmental measures in and around the Spada Lake reservoir and Sultan Basin.
