The original town of Dillon was built as a stage stop and trading post on the northeast side of the Snake River. The town was named for Tom Dillon, a prospector, and was incorporated in 1883. By 1892 the town had been relocated twice, both times in order to be closer to railroad lines that were extended into the area. All three of these historic townsites were situated very close to the Blue River Valley confluence where the Blue River, Snake River and Tenmile Creek flowed in, and this area is now referred to collectively as "Old Dillon".
During the Great Depression, The 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, completed in 1963, (which would help supply water to Front Range communities was going to flood Dillon and the surrounding valley. About a mile to the north, some land on a hillside was set aside for the current townsite, which is now situated on the shoreline of Dillon Reservoir.
The boom of recreational skiing which occurred in the late 1960s turned Dillon into a bedroom community for the seasonal workers who worked at the various ski resorts in Summit County. With the completion of the Eisenhower Tunnel which goes through the Continental Divide near Loveland Pass, commercial business also started to locate in Dillon. The town now is a thriving community and enjoys a unique quality of life as a result of their fantastic alpine environment, and great outdoor activities.
