Lake Information

With a shore that stretches on for 40 miles and a total surface area of more than 7,000 acres, Lake Granby is truly a sight to behold. The modern Lake Granby was created along with the Granby Dam in 1950, but the lake had a boating presence even before it grew with the dam's creation. Since 1902 the lake has been home to the Lake Granby Yacht club. The club is home to Colorado's most committed sailboat racers. If you're not looking to join a yacht club, you can rent or charter a boat at the Indian Peaks Marina, Beacon Landing Marina, or Highland Marina. With a lake the size of Lake Granby, there are plenty of options to choose from!
