Coal-fired power plants are closing, or being given firm deadlines for closure, across the country. In the Western states that make up the overallocated and drought-plagued Colorado River, these facilities use a significant amount of the region's scarce water supplies.

With closure dates looming, communities are starting the contentious debate about how this newly freed up water should be put to use.

When Blondie's Diner closes around 9 p.m. and a table of hunters finish their green chili cheeseburgers and head back to their hotel, the town of Naturita feels a bit like a ghost town.

There are two new marijuana dispensaries still open late with green neon signs, but on a November night at the start of hunting season, not many customers are partaking.

The only sound punctuating through the cold evening is a semi-truck idling in the parking lot of the Rimrocker Hotel, its driver trying to stay warm.

It's a good day when Tammie Delaney hears a train rumbling down the tracks outside of the century-old granary building she owns in Hayden.

"Oh, you get the train noise today!" she shouts as a train whistle pierces the usual silence in the small town of about 2,000 people.

The train whistles are an indicator of the economy in the Yampa Valley.
