This subterranean drainage system is reportedly connected to Sunken Lake, Shoepac Lake, Devil’s Lake, and Misery Bay. No one has seen or explored this alleged underground drainage way, but geological evidence supports its presence. According to Will Gregg, during the 1925 event, citizens expected to find dead trout in the dry lake bed, since Rainy Lake is normally a productive trout lake. Much to their surprise, no dead fish were found, yet the following year, when the lake reappeared, the trout also came back. Obviously, the fish had been swept into the subterranean passageways with the water, only to reappear with the water at a later point. In the same account, a story is told of another early attempt to float lumber down the Rainy River. Immediately prior to the log run, the lake drained through the sinkholes. The lumberers consequently built a rail line on the dry lake bed. After the logs were shipped, the Rainy Lake sinkholes again became plugged, and the lake reappeared.
