In 1885, the Montezuma Valley Irrigation District completed a tunnel that moved water from the Dolores River to the Montezuma Valley. This trans-basin diversion allowed the town of Cortez and the entire valley to grow and thrive. But this transfer, and later McPhee dam, changed the Dolores River. A hundred and fifty years later, the community is working to find a balance between keeping the water it has long relied on, and meeting federal requirements for healthy fish and a protected river downstream. Reporter Stephanie Paige Ogburn has more on those efforts.
