Water: Climate Change and Water

Montane (Intermountain West) Climate Change and Water

The montane (intermountain west) climate region covers the mountainous parts of Washington, Idaho, Oregon, Montana, Wyoming, California, Nevada, Utah, Arizona, Colorado, and New Mexico. It includes three glaciated mountain ranges: the Rocky Mountains, Sierra Nevada, and the Cascades.

The primary climate concerns in this region include impacts related to changes in snowpack, stream flows, and vegetation. For more information about the impacts of climate change, visit EPA's main climate change website.

The Western Water Assessment Exit EPA Disclaimer uses a multidisciplinary approach, working with climate, water, and law experts to provide information about natural climate variability and climate change. The organization hopes to assist water-resource decision-makers with its tools, specifically its climate forecasts and regional vulnerability assessments.
