Dillon is ahome rule town located inSummit County,Colorado, United States.[1] The town population was 1,064 at the2020 United States census, a +17.70% increase since the2010 United States census.[6]
The original town of Dillon was built as a stage stop and trading post on the northeast side of theSnake River.[8] The town was named for Tom Dillon, a prospector,.[9] The Dillon, Colorado, post office opened on October 24, 1879,[10] and the Town of Dillon was incorporated on January 26, 1883.[1] By 1892, the town had been relocated twice, both times in order to be closer to railroad lines that were extended into the area.[8] All three of these historic townsites were situated very close to theBlue River Valley confluence where the Snake River and Tenmile Creek flowed in, and this area is now referred to collectively as "Old Dillon".
During theGreat Depression,Denver Water began acquiring land around Dillon. In 1956, residents and business owners in Dillon were notified that they would need to sell their property and move out, because Denver Water was about to begin construction on a dam just downstream from the town, and the resulting reservoir (which would help supply water toFront Range communities) was going to flood Dillon and the surrounding valley. About a mile to the north and approximately 160 feet (50 m) higher inelevation, some land on a hillside was set aside for the current townsite, which is now situated on the shoreline ofDillon Reservoir.[8]
At the2020 United States census, the town had a total area of 1,487 acres (6.018 km2) including 531 acres (2.149 km2) of water.[6] Dillon Dam and its reservoir (Lake Dillon) are adjacent. Thecontinental divide is approximately ten miles (16 km) east.
According to theKöppen climate classification, Dillon has an alpinesubarctic climate(Dfc). Summer days are usually warm, but with nights dropping close to freezing. Winter days are cold, with massive amounts of snowfall.
