The proposed Flaming Gorge Pipeline project aims to divert 250,000 acre-feet of water per year from the Green River in Wyoming to the Colorado Front Range to meet growing demand. However, it faces significant opposition from Wyoming and Western Colorado interests over environmental and economic concerns. The project would drop water levels in the Flaming Gorge Reservoir by up to 30 feet and decrease recreation revenues in the region by tens of millions per year. At an estimated cost of $6-9 billion to construct and $217 million annually to operate, it is also far more expensive than other water plans. There is ongoing debate around water rights, conservation efforts, and how to balance the needs of urban and agricultural users across the Colorado River basin.
