The battle over one of the Colorado River’s oldest, non-consumptive water rights continued this week during a 14-hour Colorado Water Conservation Board hearing over whether the rights could be used for the environment.

The Colorado River District is seeking to acquire the Shoshone water rights — tied to a hydropower plant on the Colorado River in Glenwood Canyon — from Xcel Energy for $99 million. The River District, a governmental entity representing 15 Western Slope counties, is proposing to add an instream flow agreement to the acquisition, which would allow a certain amount of water to remain in the river for environmental benefits.

While the state’s water board — the only entity that can hold an instream flow water right in Colorado — was set to decide on the proposal this week, this was pushed to November after the parties agreed to take more time to reach a consensus on the proposal.
