BOZEMAN - City officials in Bozeman want to build a dam on Sourdough Creek to supply enough water to allow the city to double its population to about 80,000 residents.
Mayor Jeff Krauss says he would like to see the dam built within 10 to 15 years.
City engineer Brian Heaston says the dam would be built downstream from the old Mystic Lake dam, which was breached by a landslide in 1984 and knocked down in 1985.
City officials say the dam will cost up to $50 million.
Bozeman resident Steve Kelly serves on the Alliance for the Wild Rockies's board of directors and opposes the dam. He says the area for the proposed dam is popular for recreation and is home to moose, elk, mule deer and other wildlife.
