Events / Twin Lakes Tunnel & Diversion Tour - July 19

Twin Lakes Tunnel & Diversion Tour

Learn firsthand how up to 40% of the Roaring Fork River headwaters are diverted under the Continental Divide to the Front Range. Staff from Twin Lakes Reservoir & Canal Company and Roaring Fork Conservancy will lead an informative tour of the tunnels, dams and ditches that move water east. We’ll tour Lost Man Reservoir and the Roaring Fork collection dam & tunnel before 4-wheeling with Blazing Adventure’s on Lincoln Creek Road. Our destination will be Grizzly Reservoir, to get an inside look at the four-mile long Twin Lakes tunnel.  

Please bring water, snacks, lunch and questions for our experts about the plumbing of the Roaring Fork headwaters.

Please dress appropriately which includes layers for quickly changing weather during this high elevation program. This includes closed-toed shoes and rain gear as the tour will happen rain or shine.
