By 1917 the four mines in the Treadwell complex - Ready Bullion, Mexican, 700 and Treadwell - had a working depth of 2,800 feet and some 10 million tons of ore had been removed from below tidewater level. At this time the land was also beginning to subside in several areas in the mining complex. On the evening of April 21, 1917, three of the four Treadwell mines flooded. An estimated 3 million tons of seawater filled this space in 3 1/2 hours. The three mines closed down after the cave-in of 1917. The foundry and one power plant continued to operate until the Alaska-Juneau gold mine in Juneau closed in 1944.
