Dam Elimination Spurs the Return of Salmon—and a Native Tribe’s Hopes of Sustainable Fishing – State of the Planet

After a long time of ready for 2 dams to come back down on the Elwha River on Washington State’s Olympic Peninsula, and one other decade of monitoring salmon populations, the Decrease Elwha Klallam Tribe (LEKT) was lastly capable of open a small ceremonial and subsistence Coho salmon fishery this previous October. As different salmon populations battle to outlive the impacts of local weather change and human growth within the Pacific Northwest, the story of the Elwha’s returning Coho salmon supplies hope for different communities working to avoid wasting their very own fish.

The Elwha River is fed by a number of glaciers and perennial snowfields within the Olympic mountains and is dwelling to salmon, lamprey, otters and elk which have sustained Indigenous peoples within the area since time immemorial. The identify “Elwha” comes from the Quileute phrase for elk, an plentiful species on the Olympic Peninsula and in Olympic Nationwide Park. 

Within the early 1900s, hydroelectric energy enormously expanded within the Pacific Northwest, the place robust rivers may very well be become vitality for rising cities. The Elwha was no exception. In 1913, the Elwha Dam was accomplished 5 miles upstream from the mouth of the river, and the Glines Canyon Dam adopted swimsuit eight miles upstream in 1927. Collectively the dams powered the close by metropolis of Port Angeles, which rapidly turned a logging hotspot after the hydroelectricity produced was used to energy a pulp mill. 

In contrast to many different dams within the Pacific Northwest, the dams on the Elwha River didn’t embody any fish passage to assist salmon migrate upstream. Consequently, salmon populations coming back from the ocean to spawn had solely 5 miles of habitat—a small fraction of the 145 miles of streamside habitat alongside the mainstem and tributaries they beforehand had. This quick part rapidly turned unsuitable for salmon for the reason that gravel and different sediments they should construct nests and spawn constructed up behind the dams, and few aspect channels and swimming pools of slower transferring water existed in that stretch for the fish to journey. 

This case rapidly led to the decimation of culturally and economically vital salmon runs that Indigenous peoples just like the LEKT had relied on all through their lengthy historical past within the area. Elwha sockeye salmon at the moment are extinct, and the opposite six fish species populations stay critically endangered or threatened underneath the Endangered Species Act. 

Nonetheless, public opinion of the dams started to shift over the twentieth century. The institution of Olympic Nationwide Park in 1938 elevated conservation efforts and consciousness of the plummeting ranges of salmon populations. The creation of a small hydroelectric facility on non-salmon streams close by additionally rendered the hydropower created by the opposite dams much less vital. These modifications paralleled nationwide tendencies, with a big uptick in dam opposition after the mid-Nineteen Eighties. 

In 1992, Congress handed the Elwha River Ecosystem and Fisheries Restoration Act, authorizing the elimination of the dams to revive salmon populations and the Elwha River ecosystem. The federal authorities then spent years evaluating the environmental impacts of various sorts of elimination and getting collectively the funding and means to proceed. The dams had been lastly eliminated between 2011 and 2014, and fish populations have been slowly recovering, spurred on by restoration efforts by the LEKT, the Nationwide Park Service and native nonprofits.

Final October, for the primary time in over a decade, the LEKT exercised its treaty proper to reap salmon from the Elwha River. A earlier courtroom ruling from 1974 had established that tribes had the suitable to fish and hunt in all their “ordinary and accustomed locations,” however the LEKT first invested money and time into salmon restoration initiatives and monitored the fish till numbers reached sustainable ranges. 

In an interview with GlacierHub, Vanessa Fortress, a member of the LEKT and a pure useful resource technician for the tribe, defined this resolution, saying “we knew it was needed [to have the moratorium] however it was a really tough time for us as a result of salmon have all the time sustained us.”

Final fall, the LEKT noticed that Coho salmon populations had been lastly wholesome sufficient for them to reap a small quantity and feed their tribe. On October 9, 2023, the tribe held a celebration on the banks of the Elwha with singing, dancing and praying by the tribal neighborhood earlier than formally opening the fishery. 

Over 100 tribal members signed up for permits issued by the tribe on the primary day, and the fishery remained open till 177 coho had been caught (of the 7,000 anticipated to return). Households introduced youngsters who fished for salmon on the Elwha for the very first time of their lives.

Fortress highlighted the magnitude of the day, saying “you would really feel the anticipation coming into [the fishery] by our folks.” 

Wider Implications of this Fishery

Along with the immense non secular worth of the Coho salmon fishery on the Elwha for the LEKT, it has additionally offered a narrative of inspiration for different dam elimination initiatives within the Pacific Northwest geared toward restoring salmon populations.

In January, crews breached the final of 4 dams scheduled for elimination on the Klamath River in Oregon and California, and development efforts proceed to revive the basin to its free-flowing type. The Klamath Basin has seen huge fish die-offs and declines in salmon populations up to now few a long time because the dams have exacerbated poor water situations attributable to droughts. Watching salmon return on the Elwha supplies hope to communities on the Klamath working to revive their very own populations.

Within the Pacific Northwest, many salmon populations are struggling as glaciers shrink, waters heat and river habitat deteriorates. Nonetheless, regardless of research exhibiting the Olympic Peninsula has misplaced intensive glacial protection and is already affected by worsening water situations, the salmon populations on the Elwha have been bettering after the dam elimination and restoration efforts. Nonetheless, Chinook salmon populations aren’t but at sustainable ranges for a fishery to open, which means quite a lot of work will have to be performed. Collaborations and partnerships between Indigenous peoples and river administration companies will proceed to be very important to bringing salmon again to sustainable ranges. 

The story of the Coho on the Elwha gives an vital message: modifications in land use and restoration of a important stream habitat may help defend and restore salmon whilst local weather change looms. The elimination of the Elwha dam was an extended and arduous course of, however bettering salmon numbers and the return of a Coho fishery for the LEKT present that land-use modifications are a key factor within the struggle to guard ecosystems, fish and folks.
