History & Status of the Fishery
Madden Lake is located approximately 12 miles northeast of Ely. It has a surface area of 37 acres and a maximum depth of 24 feet. Access is by a 0.8 mile primitive road from CR 18 or a 0.6 mile portage from Greenstone Lake. Most of the surrounding land is State of Minnesota School Trust Land.
There is an inlet from Wedge Lake and two small inlets from local drainages. The outlet is to Sourdough Lake. Rocky falls and beaver dams limit fish movement in the inlets and the outlet. Madden Lake has a history of periodic winterkill from low dissolved oxygen.
