Snoqualmie River Work

The Snoqualmie Tribe is committed to restoring and recovering the natural riparian habitat along the Snoqualmie River. The Environmental and Natural Resources Department works to monitor and maintain river banks and water quality in both the upper and lower valleys of the Snoqualmie River.

Work for the Snoqualmie River spans multiple programs including Water Quality, Restoration & Management, GIS, and Outreach. While we monitor the river throughout the year, it’s the important volunteer work that we receive at Restoration Volunteer Events that helps to keep the riparian habitat natural.

Upper Snoquamie Reslient River Corridor Management Plan


The Upper Snoqualmie River Resilient Corridor Project is a research and planning project that the Snoqualmie Tribe is conducting to hear from the Tribal Community in particular, and the broader community at large, about what they see currently happening to this part of the Snoqualmie River and surrounding land, what is important to them and their relationship to the river, and how they think it will change in the future.

2019 Freshwater Mussel Survey

Lower Snoqualmie River

Freshwater Mussel Monitoring Surveys


Freshwater mussels are an understudied species. However, they are an extremely important part of the ecosystem yet they face numerous threats. Performing field surveys helps give better understanding to the habitat needs of freshwater mussels and their current population status.

Adult Salmonid Monitoring Program


The Adult Salmonid Monitoring Program at the Snoqualmie Tribe is expansive in the kinds of habitat that salmon are monitored. While Snoqualmie Falls is a natural fish barrier in our Snoqualmie Watershed, there are salmon who make their homes in the lower Snoqualmie River.

It is for this reason that restoration of waterways above Snoqualmie Falls are just as important for salmonid species as restoration of waterways below Snoqualmie Falls. Furthermore, just as our local habitats need salmon, our local salmon populations need habitats that can support diverse animal species.

Salmon populations are also not always ocean inhabitants. The freshwater kokanee salmon of Lake Sammamish have lived in the lake since time immemorial. Their species has naturalized to the lake and has grown with the Snoqualmie Peoples throughout time. Now, their species is threatened by our changing climate, as well as invasive predators.
