About the Sultan River

The Sultan River drops out of the Cascade foothills through a steep bedrock canyon and joins the Skykomish River at the town of Sultan, an hour from Seattle. Its flow is controlled by Culmback Dam and Spada Lake, which supply water to Everett, and the river below the diversion dam is one of the more interesting managed rivers in western Washington precisely because the management has changed. Flow regimes on this reach have been rewritten in recent decades explicitly to support salmon and steelhead, and fish passage and habitat work have reopened water that was effectively written off.

The gauge below the diversion dam reports discharge, stage and water temperature, and all three are worth reading. Releases are operational and stepped rather than weather-driven, though the unregulated tributaries below the dam still add a rainfall response in the wet season, so the lower canyon can come up after a Cascade storm even when the dam is steady. Temperature is the reading that matters most for fish, because a deep-release tailwater in a coastal watershed can run cold enough to slow the fishing and, in summer, cold enough to make this the best water in the valley.

The fishery is an anadromous one. Winter and summer steelhead are the headline fish, coho and chinook use the river, pink salmon appear in odd-year runs and chum enter the lower reach late in the year. Resident and sea-run cutthroat are present throughout, bull trout are protected and must be released, and mountain whitefish are common. Seasons and gear rules on this system are restrictive and change year to year, so the state regulations must be checked before every trip. Access is at Sultan and by trails into the canyon.

Seasons

Spring: high flows with steelhead in the system, and regulations that close much of the water to protect wild fish.

Fall: salmon enter on the autumn rains, with coho and chum in the lower river and the best variety of the year.
Winter: winter steelhead season, high water after Cascade storms, and difficult but rewarding fishing for those who time it.
