Waterwheel, Historic waterwheel in McCoy, Eagle County, Colorado, United States.

The Waterwheel is a 40-foot (12 m) high, roughly 6-foot (1.8 m) wide water-lifting wheel southeast of McCoy, Colorado, on the Colorado River. It was built of jackpine logs shaped with hand tools, and its 35 buckets around the perimeter lift water 32 feet (9.8 m) into a wooden trough that feeds an irrigation ditch.

Constructed in 1922 by rancher Earl Brooks using jackpine logs and hand tools, this waterwheel served as essential irrigation infrastructure during the early agricultural development of Eagle County.

The waterwheel represents the resourcefulness and engineering ingenuity of early 20th-century Colorado settlers who utilized local materials and natural river power to sustain their agricultural communities.

The wheel stands in the Colorado River southeast of McCoy, in Eagle County; the sources record no visitor facilities, signage or set opening times, so treat it as a roadside structure seen from the bank. Its buckets could be raised clear of the water in winter to prevent ice damage and lowered again to catch the current.

This structure remains the last surviving waterwheel of many that once operated along the Colorado River, making it an extremely rare example of early water-lifting technology.
