At 100,000 miles of waterways, Idaho has a treasure trove of incredible rivers. That also means Idaho has a lot to lose.

Idaho's rivers provide drinking water, recreation, hydroelectric power and crucial habitat for fish and other wildlife species. Idaho's rivers are the lifeblood of the state's cherished open spaces and wild country.

Nobody wants to see Idaho's rivers soiled or abused, but often there's a dramatic imbalance between the desires of hydroelectric companies, agribusiness, mining corporations and other interests and the sustainability of our unpolluted rivers and native fish populations. 

At Idaho Rivers United, we take a comprehensive look at the many forces that impact rivers and fish, including dams, mining and municipal water use. We work to change unsustainable water policy. We initiate local campaigns and have offered grants for water conservation. We strive to place many of Idaho's untouched rivers under state protection or national Wild and Scenic designation.
