What divers may encounter

Three reviewed connections are featured here. Sightings vary by season, conditions, and chance, so they are never guaranteed.

Possible deep cold-water encounter

Lake Trout

Salvelinus namaycush

Michigan Shipwreck Research Association documents the wreck at about 160 feet in Lake Michigan. NOAA identifies lake trout in deep sanctuary waters and around wreck-supported forage habitat, so an encounter is possible but never assured.

Possible deep-structure encounter

Burbot

Lota lota

At roughly 160 feet, Ann Arbor No. 5 provides the deep, low-light hard structure where NOAA reports burbot are often observed on Great Lakes wrecks. Look near the hull and lakebed.
