City of Ainsworth was a paddle steamer sternwheeler that worked on Kootenay Lake in British Columbia, Canada from 1892 to 1898.

Passengers and crew were quick to throw the firewood overboard, but then the water rushed down onto her stern and she turned broadside and began to roll in the waves.

One of the lifeboats was regained and Captain Lean, joined by Seaman Donnelly and Engineer Kale rowed four passengers 3.2 km (two miles) through the storm-tossed water and deposited them safely at the shore.

No previous attempts to dive down to the wreck had been conducted due to its extreme depth, the low visibility in the water and the dangerous surface conditions on Kootenay Lake.
