Lake Estes, man-made reservoir in Colorado, United States

Lake Estes is a reservoir in Larimer County, Colorado, created by the Olympus Dam and covering about 185 acres. The water is used for boating, fishing, and paddling, with a paved trail around the shoreline offering walking and cycling routes with views of the surrounding mountains.

The lake was created in 1949 when the Olympus Dam, standing 70 feet high, was completed to provide drinking water for the growing town of Estes Park. A power plant on the western shore began generating electricity the following year and continues to support the area's infrastructure.

The marina offers pontoon boats, paddle boats, and kayaks for rent, with seasonal hours varying and extended availability from late May through early August. Visitors should know that swimming is not permitted, boating is restricted to daylight hours, and all passengers must wear lifejackets at all times on the water.

Lake Estes lies at 7,522 feet (2,293 m) in elevation and holds 185 acres (75 ha) of water on the Big Thompson River, with roughly 4 miles (6.4 km) of shoreline. It is one component of the Colorado-Big Thompson Project, a water-diversion system that moves water across the Continental Divide.
