A coalition of high-profile businesses have signed up to add additional water for fish, farmers and hydropower generation to a key segment of the drought-stressed Colorado River.

A monitoring program is trying to ensure that Aspen Skiing Co.’s increased water use for snowmaking won’t harm area creeks.

A farmer and environmentalist formed an unlikely partnership to improve fish habitat in the San Luis Valley.

The cities of Aurora and Colorado Springs are looking to develop additional water in Eagle County and divert it to Colorado's Front Range.

Beavers are making a comeback as researchers look for ways to restore rivers and wetlands while improving the health of drought-stressed aquifers.

After a year of anxious waiting, scientists and researchers who’ve helped build one of the most successful species recovery programs in the nation have gotten a 13-year extension to finish their work.

As Colorado grapples with a demand-management program, there could be unintended consequences for animals that use irrigated agriculture for habitat.

The move is meant to help humpback chub, bonytail, razorback sucker and Colorado pikeminnow in an often-depleted section of the Colorado River.

It has survived invasive predators, too-cold water, poisoning, electro-shocks, and a ginormous dam. Still, the chub persists.

Voluntary agreements in California have been touted as an innovative and flexible way to improve environmental conditions in the Sacramento-San Joaquin Delta and the rivers that feed it. The goal is to provide river flows and habitat for fish while still allowing enough water to be diverted for farms and cities in a way that satisfies state regulators.
