The LCO Fishery
COLA's Fish Management Plan
The WDNR with COLA's help prepared a long-term Fish Management Plan for LCO in 2006. This plan guides fishery management efforts on big and little LCO, and the Billy Boy Flowage. The fishery management plan was based upon a shared vision that was developed by combining information from statewide angler surveys, onsite creel surveys, and interactive input from local stakeholders and tribes.
LCO is a rare Two-Story Fishery
What makes Lac Courte Oreilles so special and a world-class fishing lake? It is a two-story, cold-water fishery, one of only 200 on Wisconsin. It's fragile, and it's threatened by excess phosphorus and oxygen depletion.

Esox Recovery Plan
The Esox Recovery Plan on Lac Courte Oreilles was introduced by the WDNR and is the joint effort of Muskies Inc., Walleyes Forever, the LCO Tribe, COLA, and the WDNR.
Mike Persson who, along with being a member of COLA’s board of directors, represents the Hayward chapter of Muskies Inc. in their efforts to reinvigorate the musky population in LCO. Since 2016 nearly 4,000 northern pike have been removed from LCO. This ensured better survival of the 3,500 muskies and 51,000 walleyes used to restock the fishery in 2017. Mike is also working to not only re-establish musky spawning in Musky Bay, but potentially, along with the LCO tribe and others, restore wild rice habitat and possibly treat the phosphorus laden sediment in Musky Bay. There are some big projects in the work.
"This was a big year for fisheries activity on LCO. A collaborative effort between DNR, LCO Conservation Department, Hayward Lakes Chapter of Muskies Inc., and COLA resulted in the removal of 3,000 northern pike (average length around 20 inches) in the spring and the stocking of huge numbers of walleye and musky in the fall. The walleye stocking is needed, and we hope those fish will do well and be available to anglers as legal size fish in a few years (typically 4-5 to get to 15 inches). But I am particularly excited about the musky stocking. These fish were held in the hatchery longer than normal and were given extra feed purchased by Muskies Inc. That resulted in a higher average size which should improve survival. Each fish is carrying a tag that will allow us to track their growth and survival in LCO and will tell us if they move into any of the other connected lakes. That data will be very helpful as we try to restore the LCO musky population. The tags were purchased with a donation from COLA and Muskies Inc."
Totals for 2017:
Walleye: 28,353 "medium" fingerlings stocked in July (Avg. length 3-4 inches)
23,000 extended growth fingerlings stocked in October (Avg. length 6-8 inches)
3,474 large muskellunge fingerlings stocked in October (Avg. length 12.6 inches)
