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

Lake Trout
Salvelinus namaycushChoctaw lies in about 300 feet of Lake Huron. Lake trout are documented deep-water predators, so an encounter is possible near the wreck but should never be expected.

Lake Whitefish
Coregonus clupeaformisNOAA identifies lake whitefish as an important Lake Huron stock. At Choctaw, a sighting would most likely be near the bottom or a fish passing the wreck.

Burbot
Lota lotaNOAA notes that burbot often appear at deeper Lake Huron shipwrecks. Divers may see one close to Choctaw's shaded structure or the surrounding bottom.

History and significance
At the close of the Civil War, iron and steel ships began to dominate the shipbuilding trade, ultimately replacing the traditional wooden hulls of America's merchant fleets. The ship-building city of Cleveland, Ohio, with abundant coal, iron, and capital, naturally turned to steel and the innovative vessel designs it made possible. Soon, shipyards were producing larger and more efficient cargo carriers. The straight back or "monitor" design, a direct descendant of the iconic whaleback design, appeared in 1892. This design, produced by the Cleveland Ship Building Company, had a conventional bow, but the ship's metal sides slanted outward from the main deck to the waterline at almost a 45 degree angle. The hull resembled later submarines. All cabins were located at the stern, and the smoke stack was straight up and down. The "monitor" never fully developed as a ship class and only three were built: Andaste , Choctaw , and Yuma . Choctaw was 266.9 feet in length, with a beam of 38.1 feet and a 17.9 foot depth of hold. The ship registered 1,573 gross tons, with a capacity of 3,050 tons. It was powered by a 900-horsepower triple expansion engine and two Scotch boilers. Like many Great Lakes ships, Choctaw was not immune to mishaps. In April 1893, an engine explosion killed two crew members. The vessel sank at Sault Ste. Marie in a collision with the steamer Waldo in May 1896. A few years later, in May 1900, Choctaw grounded near Point au Pins, and in April 1902, Choctaw struck a rock at Marquette and partly sank after getting inside the harbor. The ship's fatal blow came on July 12, 1915, off Presque Isle. Up-bound in a dense fog with a cargo of coal, Choctaw was hit between No. 1 and No. 2 hatches by Canadian Steamship Company freighter Wahcondah . Although the ship sank in
Before you arrive
Access notes
Technical dive only. Confirm current conditions, mooring status, gas plan, decompression plan and operator requirements before departure. NOAA coordinates are reference points, not navigation instructions.
Plan within your training
Conditions and hazards
Depth beyond recreational limits, decompression obligations, cold water, limited light, changing visibility, entanglement and possible wreck overheads. Penetration requires separate wreck-penetration training and planning.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
