It’s finally cooling down and the brilliant yellow fall colors that mark Colorado’s high country are in full swing.

Depending on the elevation and location, you can witness the aspen’s fall colors — ribbons of gold threading Colorado’s high-country valleys and peaks — from mid-September to mid-November, according to Visit Denver.

And, lucky for us, the height of the fall colors is different at each of Denver Water’s mountain facilities as the seasonal change sweeps across Colorado, north to south, over the next few months.

The leaves have already started turning on the north side of Denver Water’s collection system, up around the Williams Fork Reservoir and Fraser River in Grand County. And we’re looking forward to following the change of seasons as it moves through the area around Dillon Reservoir, our largest storage reservoir, in Summit County, then through the South Platte River basin on the south side of our collection system.

We’re sharing some pictures from the Williams Fork Reservoir, which was finished in 1959 and located at an elevation of 7,600 feet.

Williams Fork is open year-round for hardy types who like camping. The boating season ends at the end of October.

Denver Water offers other spectacular sites in and near our water collection system, which spans the Rockies . You can meet some of the people who work in these environments, and throughout Denver Water’s system, by taking the “Journey of Water.”

And here’s a list of Denver Water recreation locations where you can get out and out play. Make a list, check it twice and enjoy.
