Upper Missouri Waterkeeper

The world’s largest private campground company is butting heads with conservation groups and ranchers over waste water at their popular sites in West Yellowstone.

Federal regulators call nutrient pollution one of the country's most widespread environmental problems. The state of Montana is trying to hammer out narrative standards to regulate it.

The groups want the utility company to pay for an ecological assessment on the Madison River, including an inventory of the brown trout population.

A federal appeals court says that the state of Montana and the U.S. government are within the bounds of the law in granting three dozen Montana wastewater treatment plants an exception to clean water standards.

Where there are stressed fish, there are stressed fishing guides. As Montana and much of the west feel the effects of persistent drought, those with a line in the future of the state’s fisheries are navigating high temperatures, low flow and closures across the state.
