Lake Granby is the largest and most popular of the three lakes in this Colorado River headwaters area. Elevation is 8280 ft. with a surface area in excess of 7250 acres. Lake Granby, with its 40 miles of shoreline, is a great place to enjoy fishing, boating, waterskiing, windsurfing and camping. Lake Granby is routinely stocked with brown trout, rainbow trout, kokanee salmon and contains a growing stock of Mackinaw trout. Ice fishing is allowed during that season.

All boats are allowed on Lake Granby, with boaters expected to follow the inspections for Quagga and Zebra mussels. When inspectors are not available, boaters are expected to follow the Clean, Drain and Dry protocol and be state-certified inspected before entering a new location.

Lake Granby is a man made reservoir with a deepest depth of 220 feet. The reservoir serves the Front Range Greely area of Colorado.
