Lake Chelan is the 3rd deepest lake in the United States and the 26th deepest lake in the entire world.
Lake Chelan exhibits the highest classification of water quality and clarity in WA State. Let’s keep it that way.
Lake Chelan is an ultra-oligotrophic lake. These lakes’ low algal production allows for the water to be clear.
Our lake is irreplaceable. Let’s protect what we have.
