We're working with partners to improve oxygen levels and reduce toxic chemicals, such as PCBs, in the Spokane River basin. Many projects and studies, intended to improve and protect all 112 miles of the river and Lake Spokane, are complete or underway.
Collaborative efforts help us identify ways to improve the river and lake health for many uses, including hydropower, wastewater management, fish habitat, and recreation.
What's in the Spokane River?
Spokane River suffers from low oxygen and high levels of polychlorinated biphenyls (PCBs) and metals, which are bad for fish and other aquatic animals.
Because of the presence of PCBs in fish, the Washington Department of Health issued a Health Advisory for eating Spokane River fish.
Working to meet water quality standards
We review and reissue clean water permits to ensure facilities that release wastewater continue to meet clean water requirements. In the Spokane River, these requirements include strict limitations on pollutants like phosphorus and PCBs.
Along with our partners, we've developed several plans that set targets to improve the health of the Spokane River, Lake Spokane, and their tributaries. These plans:
- Set limits on how much pollution cities and industry can release into the river and still maintain good water quality.
- Recommend actions to help prevent pollution from sources such as stormwater, forestry, and agricultural runoff.
We’re currently working to reissue permits for five wastewater treatment facilities that discharge into the Spokane River to include new clean water requirements for PCBs.
Who releases wastewater into Spokane River?
Five facilities currently release wastewater into the Spokane River:
Reducing pollution from other sources
Local conservation districts, environmental groups, and Avista are also working on additional projects to improve the health of the river.
