Maple Bluff Dive Site
Lake Mendota has many great topical features including holes, slopes and a couple of walls. The Maple Bluff dive site is directly in front of the rising rock out cropping in Maple Bluff. The dive explores the continuation of that bluff under water and the surrounding structures.
There are some fish cribs in the area that provide a great habitat for bass and panfish. Larger fish including sturgeon have been seen trawling the deeper reaches.
This site is accessible by boat only. Exclusive private property surrounds the bluff with no public water access point. Theoretically you could gear up at the Maple Bluff swimming beach but you would have a 2 hour 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.
