Seattle's Skagit dams come up for a new license, and the salmon are the question

How a dam gets a new license

Your Seattle City Light bill is quietly tied to three dams most ratepayers have never stood next to, up the Skagit River in the North Cascades. They run almost without notice. The lights stay on, the rate stays among the lowest of any big American city, and the power arrives carbon-free, so the dams are easy to forget. That arrangement is now open for review.

The Skagit River Hydroelectric Project, known to federal regulators as FERC No. 553, is in the middle of relicensing, the once-in-a-generation process where the Federal Energy Regulatory Commission (the agency that licenses non-federal hydropower) decides, on terms that last decades, how a dam may keep operating. The current license was issued in the mid-1990s and, at last public report, has run out its term, which means City Light is operating under annual licenses while FERC weighs a new one. None of that is unusual. Big relicensings routinely run years past the old expiration date.

The fish the dams stopped

The hardest question in the docket is older than the license. Gorge, Diablo, and Ross dams sit on a river that feeds the Skagit, the largest river flowing into Puget Sound, and they have no fish passage, meaning no built route for salmon and steelhead to get past the concrete. For close to a century the river above the lowest dam has been closed to those fish. Chinook salmon in the Skagit are protected under the federal Endangered Species Act, and they are also food for the Sound's endangered orcas, so the stakes reach well past one watershed.

Whether salmon historically climbed that high is itself contested. City Light and some early studies argued a natural barrier limited how far the fish ran; the Sauk-Suiattle and Upper Skagit tribes, who hold treaty fishing rights on the river, and several state and federal agencies dispute that reading. That disagreement, backed by competing studies in the record, is much of what FERC now has to sort out.

Cheap carbon-free power, and what the river pays

Here is the honest math a Seattle reader is really being asked to weigh. The Skagit project supplies roughly a fifth of City Light's electricity, by the utility's own accounting, though the exact share moves year to year with Cascade snowpack and rainfall. It is carbon-free, which matters a great deal under the Clean Energy Transformation Act, the state law that requires Washington utilities to reach carbon-free electricity by 2045. Power that clean and that cheap is hard to replace on a short timeline.

Fish passage, though, does not mean tearing the dams out. Removal is not on the table in this proceeding. The live question is whether a new license should require passage structures, higher minimum river flows, and habitat work, and who pays for all of it. Those conditions can cost on the order of many millions of dollars and take years to design, and reasonable parties disagree about how well passage would even work here. This desk will not pretend that is settled.

Who is at the table

Several accountable players shape the outcome, and a reader can watch each one. FERC runs the docket and writes the final license. Seattle City Light, a city-owned utility, is the applicant. The Sauk-Suiattle and Upper Skagit tribes press the fish-passage case and their treaty rights. Washington's Department of Ecology must issue a water quality certification, a state sign-off the project cannot be relicensed without, and the Department of Fish and Wildlife weighs in on salmon. NOAA Fisheries and the National Park Service, whose North Cascades complex surrounds the dams, also have formal roles.

The useful part for a ratepayer is that almost all of it is public. Settlement talks between the utility and the tribes happen partly behind closed doors, but the studies, comment letters, and any final agreement land in the FERC record and on City Light's own relicensing page. You do not have to take anyone's press release for it.

Worth watching this month

1. Watch FERC's eLibrary for new filings under Project No. 553, where study reports and any settlement agreements are posted as they arrive, the clearest signal of where things stand.

2. Watch for action by the Washington Department of Ecology on the water quality certification, a step the relicensing legally cannot skip, so it genuinely matters.

3. Watch City Light's Skagit relicensing page for any announced settlement with the Sauk-Suiattle and Upper Skagit tribes, which would reshape the whole fish-passage question.

4. Watch for routine annual license renewals from FERC, ordinary paperwork that simply signals the main decision is still pending.

5. Watch comment letters from NOAA Fisheries and state Fish and Wildlife, which tend to carry real weight on salmon-recovery conditions.
