drought

Widespread drought, hot temperatures, low humidity and wildfires across the state are hurting the ability of ranchers to produce hay this summer and reducing the quality of forage in pastures.

Fish take the heat while kayakers walk more.

In some parts of the West - like the grass and shrublands of the Idaho-Oregon-Nevada tristate area - closer to two-thirds of burned area is associated with heatwaves.

Fast, intense wildfires are making it harder for forests to recover and can change the entire ecosystem.

Nevada filed a federal lawsuit Monday challenging the Trump Administration's new rules drastically cutting the state's access to the Colorado River.

The federal decision, which imposes steep cuts on California, Arizona and Nevada, can now be challenged in court.

As the climate warms, some mountain trees are moving higher up, while others are spreading downhill. Scientists say something inside the trees may explain why. And that split could reshape watersheds and wildfire risk.

The federal government will cut back on the amount of water for Arizona, California and Nevada after years of negotiations. They will hit cities in the Phoenix and Tucson areas the hardest.

On Colorado's Upper Arkansas River, a deal is boosting water for fish and rafting

Scientists have a new name for a weather pattern reshaping how the West gets its water: so-called “snow-eater” heat waves.
