Heart Lake is so named due to its irregular shape of a valentine heart.

Heart Lake comprises about 63 acres (0.3 km²), has a maximum depth of 123 feet (37 m). The lake is a classic example of a kettle lake, many of which dot the landscape in this area. The lake holds healthy populations of splake, rainbow trout, bass, northern pike, and perch, and is popular with area fishermen. While surrounded mostly by private residences, there is one public access point along East Heart Lake Road, which is maintained by the nearby Otsego Lake State Park.^[2]
