Status of the Fishery (as of 08/11/2014)

White Iron Lake, located 5 miles east of Ely in northeastern St. Louis and western Lake Counties, is in a group of several lakes in the Kawishiwi River system often referred to as the White Iron Chain of Lakes (WICOL). The WICOL system includes Farm, South Farm, and Garden lakes. Hydroelectric dams between Garden Lake and Fall Lake and between Birch Lake and White Iron Lake control flow and water levels in the WICOL reservoir system. White Iron has a large (592,626 acres) heavily forested watershed that drains the majority of the South Kawishiwi River watershed. Numerous wetlands in the watershed are responsible for the stained color and limited water clarity compared to other lakes in the region. The water column tends to be well mixed and dissolved oxygen levels have remained above 2 ppm in depths to 30 feet. The lake is accessed via two separate public concrete ramps on the west side of the lake and navigable channel connecting the north end of the lake to Farm Lake. Rocky substrates and low water clarity limit aquatic plant growth in the lake, however plants can be found in high density in some of the shallow bays.
