This deep, clear lake has numerous holes in excess of 75 ft (23 m), and has one large island in the south end.

An interurban rail line once connected Gull Lake to nearby Battle Creek and Kalamazoo.

The lake became a popular summer getaway for wealthy families, such as the Upjohns (pharmaceuticals), the Shakespeares (fishing tackle) from Kalamazoo and the Kelloggs (breakfast cereal) from Battle Creek.

Its clear waters have made Gull Lake a local scuba diving hot spot.

A list of these include a phone booth, motorcycle, car, ice shanty, swing set, railroad tracks, and two boats.
