Carstens Lake is approximately 20 acres in size and reaches a maximum depth of about 30 feet. The public lake access has a parking space 15 car/trailer units. Several years ago, the Department of Natural Resources poisoned off the lake and a fish weir was installed within the inlet stream to block off the spawning runs of rough fish from Lake Michigan.
Adult northern pike and bass have been planted to restock the lake. Use of motors, except electric motors, are prohibited.
