Governor’s Island Dive Site

Lake Mendota has many great topical features including holes, slopes and a couple of walls. The Governor’s Island dive site starts on the sandy flat off of Governor’s Island and can continue to the ‘hole’ that can reach 80′. The dive explores the continuation of the bluff that the Mendota Health Institute sits on. Piles of rocks and boulders, dolimite and sandstone formations and the wall of 20-30′ with the base at 70′ are attractions to explore on this dive.

The area is a great place for finding anchors and fishing lures, with walleye, pan fish, carp, crappie and even gar fish being reported.

Site Details

This site is accessible by boat only. Theoretically you could gear up at the parking area off of Cinder Lane near the Mendota Health Institute but you would have an arduous walk to the water plus a long back swim to the site.

MadisonScuba loads and leaves from the Warner Park boat dock. There is ample parking on the street or under the railroad overpass the streets beyond it. A short boat ride brings you to the site.
