Located just a few miles north of Granby, Lake Granby is famous for record-size trout. The lake is routinely stocked with konkakee salmon, brown trout and rainbow trout. Lake Granby is approximately 220 feet deep and its shoreline is approximately 40 miles long. It was built in the 1940's as a reservoir for the Greeley area.

Lake Granby is great for fishing, boating, waterskiing, picnicking, and camping. Frequent sightings of bald eagles and Osprey make it a great place to just hang out for the day.
