A forfeiture of water rights may be the reason Powderhorn Mountain Resort is opening on time this year. The Daily Sentinel reported that Congressman Scott Tipton says the U.S. Forest Service forced Powderhorn to surrender water rights so the ski area could open in two weeks. Tipton has written a letter to Forest Service Chief Tom Tidwell , asking the agency to honor a past water agreement. The resort is set to open on December 15th.
