WE need you!

As competition for Idaho’s water becomes more intense, the need for a single, united voice representing Idaho’s water users is been more important than ever.

IWUA continues to monitor and guard against demands and interests, both within and outside the Pacific Northwest. Competing interests seek to assume control of water in our river systems and lakes for uses outside Idaho and for uses contrary to existing rights and authorizations.

IWUA is uniquely positioned to protect the rights of Idaho’s citizens and to fulfill a need – that of like-minded people bonding together to achieve a common goal.

What IWUA does affects every water user in Idaho. Your voice needs to be heard as a part of the Association. By being a member of IWUA, you can help shape your own destiny and that of future generations.
