This high mountain reservoir, with a surface elevation over 9,000ft above sea level, exists to service the population of Denver. Dillon Reservoir is the result of a mile long, 230ft high dam built just past the confluence of the Snake River and Blue River. Some of the water it stores is diverted into a 23 mile tunnel through the continental divide and onto the Front Range, where it accounts for nearly 40% of Denver's Hydration.
The damming of the Blue River meant that the entire town of Dillon would be submerged. Before construction began in the 1960's, a new portion of land was allocated and the townspeople were given the option of relocating their lives, at their own expense. A few buildings from the old town still survive to this day; some were moved to the new town of Dillon while others are scattered about the county.
Evidence of the town beneath the waves can be seen from two spots on Swan Mountain Road. The parking lot in the Snake River Arm is right next to the old road to Dillon, which can be seen clearly descending into the water. Also, at the top of Swan Mountain Road, at Sapphire Point, you can see another old road to Dillon making its way from Farmers Corner into the lake.
