Keep rivers flowing and save salmon

Summer is on its way. For all the warmth and joy the season brings, it can also mean danger for the fish in our rivers. Salmon need cool flowing water to migrate and spawn. Unfortunately, those flows have disappeared from many local streams. Every donation to WWT helps restore water to rivers for salmon. The first $10,000 donated until GiveBIG ends on May 7 will be matched!

Washington's Freshwater

Is There Enough?

Commonly thought of as a water-rich state, Washington's freshwater resources are at risk from past mismanagement, climate change, and increasing demand. The good news is we are doing something about it.

Thank you to our supporters!

Our Impact

Since 1998, we have worked across the state from the San Juan Islands to the Palouse restoring water to thousands of river miles in more than 50 rivers and streams.

Teanaway: A Stream Flows Again

Mill Creek flows first protected across WA/OR border

WWT has partnered with the City of Walla Walla and the Confederated Tribes of the Umatilla Indian Reservation to restore Mill Creek flows since 2021. We are excited to share that these restored Mill Creek flows are the first protected across the OR/WA border! This water is protected in both states and provides vital flow for Chinook salmon, steelhead, bull trout, and other fish.

Transforming Loup Loup Creek

WWT, the Confederated Tribes of the Colville Reservation, and the Helensdale Reclamation District saw the need to restore Loup Loup Creek for steelhead and took action. The creek is now one of the most productive steelhead streams in the Okanogan Basin.
