Did you know??  Water for the Denver area mostly comes from the Colorado River and the western side of the Continental Divide. The water supply system is complicated but can be seen in Denver Water's Water Collection system map, (Littleton highlighted with a red star). Much of Littleton’s water is from the South Platte River, but some of the water in the South Platte is piped over into the North Fork of the South Platte near Grant, via the Roberts Tunnel from Dillon Reservoir.


High Line TrailInformation about potable water supply can be found from Denver Water’s website.

Help improve recreation on the High Line Canal, which runs through Littleton.

While Littleton has a great reliable source of potable drinking water, it is always important to conserve. Water “from the tap” is one part of the overall water cycle. Saving water and restricting your personal use helps to provide water to others downstream of us in Colorado. It is important to understand that Colorado and the Denver Metro Area has a semi-arid climate. Consider ways you can be water wise and maybe save some money too!

The South Platte and Metro Basin Roundtables recently collaborated with the Openwater Foundation to develop a series of Storymaps to help educate people about the important water issues in our state.
