Antero Reservoir is a reservoir in the US state of Colorado. It was created by the first dam placed on the South Platte River in Park County, central Colorado. It is owned by Denver Water and supplies drinking water to the greater Denver metro region almost 140 miles (230 km) away.
Built in 1909, the earthen dam sat on a site believed by geologists to be a dry lake bed some 300 years old. This lake, named Green Lake, lies submerged in Antero Reservoir.
The Reservoir was closed in 2002 for five years due to drought. The lake went completely dry, and the Colorado Division of Wildlife, in concert with Denver Water resurrected it in 2007. The Colorado Division of Wildlife re-stocked the lake with rainbow trout, brook trout, cutbow, cutthroat trout, brown trout, and splake.
In 2011, engineers began lowering the water level by two feet due to excess seepage. The dam has leaked since its construction, leading it to operate under state restrictions.
Beginning May 1, 2013, Antero reservoir was supposed to have been drained because of drought conditions. It was not drained because of substantial snowfall in April 2013. In 2013, a $17 million project to rehabilitate the dam began. The reservoir is expected to be drained in 2015 for necessary repairs. Re-filling should occur in 2016.
The shallowness of this reservoir makes it relatively warm for the location and altitude. This makes for exceptionally large, fast growing fish. Antero Reservoir is owned by Denver Water and overseen by Colorado Division of Wildlife. Because it is not a state park, there are no fees for fishing. Fishing is year 'round, with ice fishing in the winter.
