On July 12, 2000, the Lahontan Regional Water Quality Control Board adopted Resolution No. 6-00-67 amending the Water Quality Control Plan for the Lahontan Basin (Basin Plan). The amendment revised the Basin Plan by removing the Municipal and Domestic Supply (MUN) beneficial use designations from nine saline water bodies. The water bodies include Wendel Hot Springs, Amedee Hot Springs, Fales Hot Springs, Hot Creek, Little Hot Creek, Little Alkali Lake, Keough Hot Springs, Deep Springs Lake, and Amargosa River.
The amendment removes the MUN designation of these waters from Table 2-1 in the Basin Plan, and also adds Amedee Hot Springs, Little Alkali Lake, and Little Hot Creek and their designated beneficial uses, with the exception of MUN, to Table 2-1. These three water bodies were previously categorized as "Minor Surface Waters" in the Basin Plan.
