The Water System

Where Front Range Water Comes From

Most people don't realize their tap water started as snow on the Continental Divide — sometimes 100 miles away.

❄️

Mountain Snowpack

Rocky Mountain snowfall from November–April becomes river flow in spring and summer. Snowpack levels directly predict how much water cities will have — and how tight restrictions will be.

🏞️

Reservoirs

Denver Water operates Dillon and Cheesman reservoirs. Boulder draws from Gross and Barker reservoirs. Reservoir storage levels determine drought stage declarations.

⚖️

Water Law

Colorado's Prior Appropriation Doctrine — "first in time, first in right" — allocates water by historical priority. Municipal utilities hold senior rights to keep taps on, even in drought.
