Northern Water collects real-time flow data for the Colorado-Big Thompson Project and Windy Gap Project. The C-BT Project contains 12 reservoirs, 35 miles of tunnels and 95 miles of canals on both sides of the Continental Divide in Northern Colorado.
The data for selected canals, streams, rivers, reservoirs and watersheds can be viewed and downloaded from the East Slope Water Data, West Slope Water Data and SnoWatch Snowpack Data pages.
