Okanogan Highlands Alliance
concerned, informed, & empowered since 1992

OHA’s Mission is to…

Encourage and support education and public participation in decisions involving the integrity, sustainability, and prosperity of our community and the environment. Foster conservation of natural resources and take action to prevent environmental degradation.


What’s New?

Mine Monitoring

OHA is focused on efforts to prevent environmental degradation and push for corporate accountability for the water quality issues at the Buckhorn Mine site. We use technical and legal avenues to advocate for actions that increase public understanding of pollutant fate and transport and could stem the flow of pollutants from the mine.

We have filed a clean water act citizen suit against the mining companies.


OHA’s education program is guided by the belief that increasing awareness of the environment will increase empathy for, appreciation of, and desire to protect nature.

OHA’s restoration program works to restore habitat and ecosystem function of natural environments including streams, wetlands, and forests. We also maintain and build trails so that people are able to access nature with minimal impact to ecosystems.
