... After efforts to develop a revised Lake Management Plan were unsuccessful, an assessment was completed in 2006 as part of an Alternative Dispute Resolution process among the CDA Tribe, IDEQ, and EPA. A key finding of the resolution process was a need for the CDA Tribe, IDEQ, and EPA to develop a consistent description of current water quality conditions in the Lake (Harty, 2007)
