All the authors participated in data collection, edited and approved the submitted version. Procedures for evaluating and prioritising the removal of fish passage barriers: A synthesis. There were at least two small areas of temperature refuge at the mouths of Cordova and Buffalo creeks where the streams created better water quality and water that was 1-2°C cooler than ambient river conditions immediately upstream this summer.
With the rapid recovery and access to high-quality habitat, recovery of Summer Steelhead is likely to continue given prudent harvest management is maintained in the future. Kornis, M., Weidel, B., Powers, S., Diebel, M., Cline, T., Justin, M., et al. Snorkeling Mount Tam's Creeks in a Search for Native Fish. Last year, due to high flows in areas where fish congregate, the snorkel survey was conducted in August.

Fish and Wildlife Service, Washington Field Office. We report two main findings that describe both the timing and extent of fish reentering formerly inaccessible sections of the watershed. Given the low population sizes of Pink Salmon prior to dam removal (Pess et al., 2008), this may have limited their opportunities to migrate past the former Glines Canyon Dam.
Data inventory page for site 12045500—Elwha River at McDonald BR near. Using observations from ongoing field studies, we compiled a timeline of migratory fish passage upstream of each dam. Many forest and aquatic creatures have benefited including Bald Eagles like the one in the photo, seen last May.

Over $30, 000, 000 (see Restoration Handout) has been spent on improved fish passage in the lower watershed.

For us, the restored salmon habitat creates a slippery obstacle course as we trek over and under downed trees to snorkel more pools further up the river. 2009 Okanogan Steelhead Broodstock and Monitoring Program Annual Report PDF. These juvenile Coho Salmon observations support the recommendation that the relocation of adult hatchery Coho Salmon is no longer necessary (McHenry et al., 2020a).
The data paints a picture of the health of the endangered species, and the entire ecosystem. Furthermore, a commercial and recreational fishing moratorium in place since 2011 eliminated any potential catch-and-release or harvest impacts to Summer Steelhead, thereby removing this stressor on population recovery. This particular one was "huge, " says the biologist, about the size of a bay leaf. In some cases, channel units longer than 200 m were divided into two or more contiguous units of the same type (usually riffles, glide-like riffles or glide-like pools) and GPS coordinates were collected at the point where channel units were divided.

No more than one to three fish in each year had a clipped fin of any kind, meaning there were very few hatchery fish that had strayed from another river system (hatchery summer steelhead are not released in the Elwha). The two hydroelectric dams (operated as run-of-river for the last four decades before removal), provided the first municipal electricity for the growing population of the North Olympic Peninsula, including the frontier town of Port Angeles, Washington.

With the increase in the more fecund Summer Steelhead in the upper Elwha and the potential for interactions between resident and anadromous forms of O. mykiss (Brenkman et al., 2008), admixture of Steelhead and Rainbow Trout could have contributed to increased fitness and population sizes of resident fish (Ohms et al., 2014). 9 km in ME (Middle Elwha, between the two former dams), and 29. 2020 Snorkel Count - link. Since she grew up along a stream in Marin County, she's actually been counting salmon for much longer. First, for migratory fish species, we report the date of the first observed fish upstream of each dam (ascertained from several ongoing field investigations using multiple techniques), to build a timeline of passage past each dam from 2011 through 2019.
Finally, our summary of first fish observations upstream of each dam provides a general timeline for understanding the temporal context of fish movement upstream after dam removal. We can not let this happen! "No fish, " she says. Torgersen, C. E., Le Pichon, C., Fullerton, A. H., Dugdale, S. J., Giovannini, F., et al.
