Replacing a few culverts under roadways in a remote area of Washington may not seem that big of a deal.
But for threatened summer steelhead, it could be a game changer.
These culverts have blocked fish passage fish passage
Fish passage is the ability of fish or other aquatic species to move freely throughout their life to find food, reproduce, and complete their natural migration cycles. Millions of barriers to fish passage across the country are fragmenting habitat and leading to species declines. The bet365下载ios's National Fish Passage Program is working to reconnect watersheds to benefit both wildlife and people.

Kate Terrell鈥娾斺奌abitat Restoration and Conservation Program Lead with the bet365下载ios鈥檚 Mid-Columbia Fish and Wildlife Conservation Office 颅鈥娾斺奺xplains summer steelhead is one of three salmonid species in the Upper Columbia listed under the Endangered Species Act. Steelhead and bull trout are listed as threatened, and spring Chinook are listed as endangered.
The final stages of the Johnson Creek Fish Passage Project have been 7 years in the making. The first of the final two projects was to break ground on Oct. 28. On Nov. 2, with snow and extended below-freezing temperatures forecast, the team decided to avoid winter construction and potential construction challenges and pushed construction to July 1, 2023, when the in-water work window reopens in Johnson Creek. This winter, the team will continue to work through pre-cast production, material procurement, submittal review and scheduling, and hit the ground running in July 2023.
When the project is complete in fall 2023, steelhead will have access to an additional 8 miles of cold water.
Bill Gale, project leader at bet365下载ios鈥檚 Mid-Columbia Fish and Wildlife Conservation Office says, 鈥淭he big story is it鈥檚 a culmination of efforts that have been going on for a long time to restore passage to this stream. This is something to celebrate.鈥
Johnson Creek is a rarity among the Okanogan River鈥檚 tributaries near the Canadian border, about 45 miles north of where the creek meets the Okanogan River in Riverside, Washington. The river, part of the Columbia River watershed, has headwaters at Okanagan Lake near Penticton, British Columbia, Canada, about 80 miles north of Riverside. The Okanogan River flows into the Columbia River near Brewster, Washington, about 40 miles to the south.
Unlike many tributaries in Okanogan watershed, Johnson Creek doesn鈥檛 descend off the plateau and run for a mile or less before joining the Okanogan River, Terrell says. Instead, it is spring-fed and runs through a valley providing 8 miles of habitat for listed steelhead.
Because of its geological features, the Okanogan basin presents fewer opportunities for summer steelhead habitat. 鈥淪teelhead need cold water. Projects like Johnson Creek are important because they provide access to the headwaters of the watershed,鈥 says Terrell.
Terrell explains access to that cold water is vital because the Okanogan River system has severe temperature issues. 鈥淏y the end of July to mid-August, a fair amount of the Okanogan hits a lethal temperature for steelhead, so being able to access tributaries with cold water meets their biological needs. It also provides some areas for spawning and rearing the juveniles.鈥
鈥淭he steelhead populations in the Okanogan are in dire straits. Restoration projects like Johnson Creek are necessary to bolster the existing populations.,鈥 says Terrell.
Theo Burgoon, project manager with Trout Unlimited, says because Johnson Creek is such a small tributary, no one really thought about removing barriers until about 8 years ago. 鈥淏ut it鈥檚 spring-fed and flows year-round, so it鈥檚 a nice little cold hideaway for summer steelhead,鈥 says Burgoon.
In recent years, populations of summer steelhead have plummeted precipitously. The 2020 Okanogan Subbasin Steelhead Spawning Abundance and Distribution report, published in 2021 by the Colville Confederated Tribe鈥檚 Fish and Wildlife Department, shows population survey results for several years. In 2014, for example, a total of 57 steelhead were detected in Johnson Creek. By 2019, that number dropped to three. While methodology changed somewhat in 2020, by then the number was zero.
Terrell says there are a number of things that set the anadromous summer steelhead apart from other salmonids. 鈥淥ne of the coolest things about steelhead is they鈥檙e really strong swimmers. Not all of these culverts are 100% passage barriers, but migration delays can affect their reproductive success. Steelhead typically live in fresh water for 1 to 2 years before migrating to the ocean,鈥 she says.
The bet365下载ios is only one of the entities working on the project. The project lead is Trout Unlimited. Other partners include the City of Riverside, Washington, and the Confederated Tribes of the Colville Reservation. The groups also worked closely with the Washington Department of Transportation.

The two projects at Greenacres and State Route 97 will correct the final three passage barriers in the lower 1.2 miles of Johnson Creek.
Terrell says replacing an undersized pipe culvert with an appropriately sized pre-cast concrete box culvert with a stream stimulation channel at Greenacres will be the first project. The final project will involve removing a 6-foot diameter pipe culvert and concrete weir/debris screen. Restoration at the State Road 97 site will include replacing the undersized culvert with a stream simulation channel, removing the weir/debris screen and grading the channel to restore passage at the site.
COVID-19-related supply-chain issues repeatedly delayed completion of the important project. The Greenacres project initially was scheduled to be complete in August. The State Road 97 project is planned for summer 2023. Both are now expected to be completed by fall 2023.
Our public lands, like our roads and bridges, require strategic investments and management to protect the fish and wildlife that is so important to the American public. The Bipartisan Infrastructure Law has committed $455 million to the bet365下载ios over five years to support our natural infrastructure and protect these valuable resources.
