Union Reservoir - 0461 CR#26
Union Reservoir is a 736 acre body
of water providing many outdoor recreational activities. Originally called
Calkins Lake, the reservoir was carved out during the last glacial age and
is one of only a few natural lakes in Colorado. In 1903, the Union Ditch Company
began drilling a tunnel to release water into the St Vrain River. According
to Colorado water law, that made Union a true reservoir. Today, visitors to
Union Reservoir can enjoy fishing, swimming, wakeless boating, camping, windsurfing
and picnicking. The Reservoir is located approximately 7 miles west of I-25.
