Hood Canal’s shoreline is doing two things at once this May. On Saturday, May 10, Marine Area 12 will open for spot shrimp at 9 a.m. — the only piece of Puget Sound with an opener two weeks before the rest of the region. A few miles up the highway in Belfair, the Mary E. Theler Wetlands Nature Preserve is heading into the most visible phase of a multi-year salmon restoration: a 1,200-foot elevated boardwalk through a salt marsh that, until recently, sat behind a failing levee.
The two stories are not separate. The shrimp fishery exists because the canal still has functioning estuaries. The estuary at Theler is being rebuilt because Hood Canal’s summer chum — federally listed as threatened — need it to survive. For Mason County families, this May is a window into both halves of the same coastline.
Marine Area 12 Opens May 10 — Two Weeks Ahead of the Rest of Puget Sound
The Washington Department of Fish and Wildlife (WDFW) has set Hood Canal’s 2026 spot shrimp schedule with five confirmed openings in Marine Area 12: May 10, May 24, May 26, June 7, and June 21. Each window runs from 9 a.m. to 1 p.m. only. WDFW has flagged that additional dates may be added later in the season depending on stock assessments — the agency’s Medium account and the Marine Area 12 regulations page are the definitive sources for any mid-season changes.
The daily limit across Puget Sound is 80 spot shrimp per licensed fisher, and the combined daily weight limit for all shrimp species is 10 pounds (whole shrimp). If a shrimper retains only spot shrimp, they may remove and discard the heads on the water; if they retain any other shrimp species, heads must stay attached until they are back on shore so officers can verify the weight limit on the dock.
The May 10 opener carries unusual weight on Hood Canal because it is the only early opportunity in the region. Most of Puget Sound waits until May 24. That two-week head start is why launch ramps from Hoodsport up through Union toward Belfair are likely to be at capacity before the 9 a.m. window opens. Experienced shrimpers tend to be on the water before sunrise, traps rigged, ready to drop the moment the season starts.
Theler Wetlands: The Levee Is Gone, the Boardwalk Is Coming
While shrimpers fish the deeper waters of the canal, the south end of Hood Canal is in the middle of a quieter transformation. The Mary E. Theler Wetlands Nature Preserve sits at the mouth of the Union River in Belfair — 22871 NE SR-3, just before the town center on Highway 3. For decades, a levee separated roughly seven acres of wetland from the tidal processes that built the marsh in the first place. As of fall 2025, that levee is gone.
The Hood Canal Salmon Enhancement Group (HCSEG) and WDFW completed the major earthwork phase last year: a failing 12-inch metal culvert was replaced with a 15-foot-wide concrete box culvert; a sinuous tidal channel was excavated through the new estuary; and a section of Northeast Roessel Road was raised to function as a set-back levee. Summer 2026 brings the most visible piece of the project — construction of a 1,200-foot elevated, piling-supported boardwalk through the restored marsh, built on the footprint where the old levee used to be.
For Mason County visitors, the practical effect is that the Theler trail loop, currently fragmented by construction, will reconnect. The preserve already draws birders, school groups, and weekend walkers; the new boardwalk turns the wetlands into a fully accessible loop through restored salt marsh — the kind of walk that, in much of Puget Sound, no longer exists.
Why the Two Stories Belong Together
Hood Canal summer chum salmon are listed as threatened under the federal Endangered Species Act. The Union River, which empties into the canal at Theler, is one of the last spawning runs left for the species. Juvenile summer chum need shallow, low-salinity, food-rich estuarine water to grow before they head out into the canal. That is exactly what the Theler restoration is rebuilding.
And juvenile salmon are not the only species that depend on a healthy canal. Spot shrimp, the prize of every May opener, live in deeper waters but rely on the broader ecological function of Hood Canal — water quality, dissolved oxygen, nutrient flow — that estuaries help maintain. When residents pull a trap full of spot shrimp on May 10 and walk a restored boardwalk in August, they are seeing two different parts of the same system.
What Mason County Residents Should Do This May
For shrimpers: confirm your Washington recreational fishing license before May 10, check the WDFW Marine Area 12 regulations page for any last-minute rule changes, and arrive early. The 9 a.m. start is hard — traps cannot be set in the water before then.
For everyone else: the Theler preserve is open during daylight hours, and HCSEG posts trail-access status at pnwsalmoncenter.org. The current spring window is a chance to see the wetlands mid-restoration, before the boardwalk goes in. By late summer 2026, the loop should be walkable end to end for the first time in years.
Frequently Asked Questions
When does Hood Canal spot shrimp season open in 2026?
Marine Area 12 opens for spot shrimp on May 10, 2026, from 9 a.m. to 1 p.m., with additional confirmed openings on May 24, May 26, June 7, and June 21. WDFW may announce more dates later in the season. Hood Canal is the only Puget Sound area with an opening before May 24.
What are the daily limits for spot shrimp in Hood Canal?
Each licensed shrimp fisher may keep up to 80 spot shrimp per day, with a combined daily weight limit of 10 pounds (whole shrimp) for all shrimp species. Spot-shrimp-only retainers may remove the heads on the water; mixed-species retainers must keep heads attached until back on shore.
Where is the Mary E. Theler Wetlands Nature Preserve?
The preserve is located at 22871 NE SR-3 in Belfair, just off Highway 3 before the town center. It is open during daylight hours. Trail access is partially affected by ongoing restoration work; current status is posted at pnwsalmoncenter.org.
When will the Theler Wetlands boardwalk be finished?
WDFW and the Hood Canal Salmon Enhancement Group plan to construct the 1,200-foot elevated boardwalk in summer 2026. The structure runs through the newly restored estuary on the footprint of the removed levee and will reconnect the preserve’s currently fragmented trail loop.
Why does the Theler restoration matter for Hood Canal salmon?
Hood Canal summer chum are federally listed as threatened. Juvenile chum from the Union River need shallow, low-salinity estuarine habitat to grow before entering the canal. The Theler project removed a levee, replaced an undersized culvert, and dug a new tidal channel to restore that nursery habitat across roughly seven acres.
Do I need a license to harvest spot shrimp in Washington?
Yes. A valid Washington recreational fishing license is required for spot shrimp harvest. Licenses can be purchased online from WDFW or at license vendors statewide. Children 15 and under do not need a license but are still subject to daily limits.
Is the Theler Wetlands trail accessible during construction?
Sections of the trail loop are currently fragmented because of restoration work. Walking access is available during daylight hours, but the full loop is not yet reconnected. The 2026 boardwalk construction is the final phase that will restore continuous loop access.
