FERC Relicensing Status

FERC issued a new 40-year license in 2004. That license sets minimum instream flows, down-ramping rate restrictions, and flow continuation capability. Puget Sound Energy is renovating or rebuilding much of the project; the upgrades will improve fish protection.  The project is expected to come back on line in the spring of 2013.
