MnDNR: Mille Lacs Lake Walleye Fishing Frequently Asked Questions (FAQ) 
By Minnesota Department of Natural Resources Q: What is happening with the walleye season this summer on Mille Lacs Lake?
A: The closure that began July 8 and was set to end July 28 is being extended by two weeks. That means walleye fishing will reopen at 6:01 a.m. on Aug. 11 for catch-and-release only through Labor Day. A night fishing closure also will remain in place from 10 p.m. to 6 a.m. through Nov. 30.
Q: How does this affect fishing for other species?
A: Fishing regulations for other species such as smallmouth bass, muskie and northern pike remain the same. During the night closure, there is an exception for muskie and northern pike anglers using artificial lures and sucker minnows longer than 8 inches.
Q: Why did the DNR extend the closure?
A: While the DNR wants to allow as much walleye fishing on Mille Lacs as possible, the state is also required to abide by cooperative agreements made with eight American Indian Chippewa bands. The two weeks of additional closure allows the state to abide by a harvest quota set earlier this year with the bands.
The DNR and the bands agreed to harvest quotas of 44,800 pounds for state anglers and 19,200 pounds for tribal fishing. They also agreed that up to 75,000 pounds of walleye could be sustainably harvested from the lake from Dec. 1, 2016 to Nov. 30, 2017 in order to conserve the population
That agreement allows the state to use a built-in buffer – the 11,000 pounds difference between the conservation cap of 75,000 pounds and the combined harvest quota of 64,000 pounds – in an attempt to allow catch-and-release walleye fishing through Labor Day, following the mid-summer closure.
The latest creel survey data shows that state anglers reached their quota of 44,800 pounds of walleye caught from Mille Lacs in early July. Even though state anglers already have caught their quota of fish, the DNR is dipping into the allowed conservation reserve in order to reopen the season on Aug. 11.
Q: Why has the walleye population in Mille Lacs declined? What is the DNR doing in the long-term to try to conserve the population?
A: The vast majority of walleye that hatch do not survive to their third autumn in the lake. Walleye numbers have declined to the point that it has become important to protect spawning-sized walleye, particularly the class of walleye that hatched in 2013. It is important to protect the large 2013 year class to replenish aging spawning stock. Most males from the 2013 class are now mature, but females will not start to contribute in large numbers until next spring. The state is committed to conserving the population of walleyes born in 2013 to improve and rebuild a sustainable population for the future.
Q: Why do we count hooking mortality during a closed walleye season?
A: The amount that state anglers can kill (as spelled out in state-bands agreements) also must include fish that die as a result of hooking mortality, the fish that die after being caught and then released back into the water. During the closure, some anglers still catch walleye incidentally and some of those fish die after being released. Under the state-band agreements, those dead fish must be calculated and counted against the state’s allocation.
Q: How did this cooperative management between the state and the bands of Mille Lacs Lake come to be?
A: Recall that in 1999, the U.S. Supreme Court upheld lower-court decisions that allowed the Mille Lacs band and seven other Chippewa bands to exercise off-reservation fishing and hunting rights. The lower federal court also set up guidelines, known as stipulations and protocols, for both sides to follow. These stipulations and protocols provide a framework for how the bands and the state must work cooperatively to manage shared natural resources, including Mille Lacs fish. In their agreements, the DNR and the bands are required to annually establish the number of walleye that can safely be harvested from Mille Lacs while ensuring sufficient remaining walleye in the lake for a healthy fishery.
Q: If the walleye population is in decline, why are anglers catching so many?
A: Fish are biting for two reasons. First, there is a shortage of food for larger walleye. Last fall’s assessment showed that larger walleye were thinner than average. Second, studies in many fisheries show that catchability actually increases when fish population decline.
In Mille Lacs, walleye congregate in preferred spots rather than disperse evenly throughout the lake. Fewer fish in the lake means there’s more room in the preferred spots for fish to gather, and anglers find these spots where they can catch a larger portion of fish. Finally, while the walleye population has decreased considerably (by half or more), the amount of fishing pressure has declined by a lot more. This means that there are more walleye per angler fishing Mille Lacs today.
Q: How is the DNR using science and research to help the walleye population?
A: Mille Lacs Lake is the most studied lake in Minnesota. It is also a complex and changing system. The agency conducts a large number of surveys on the lake annually. These surveys include assessing the abundance of young walleye; setting 52 nets to assess adult abundance; using fine-mesh nets each summer to determine abundance of food (prey fish) for walleye; and using interviews with anglers around the lake (called creel surveys) to estimate the number of fish anglers are catching. The DNR also periodically tags walleye and other species to provide actual population estimates. We are tagging bass this year in cooperation with angling groups, and will be tagging walleye in 2018 and 2019 when the 2013 year class will be reaching full maturity.
Q: What is the purpose of the external review the DNR has initiated?
A: The DNR has asked Dr. Chris Vandergoot to lead an independent review of the DNR’s scientific approaches to manage Mille Lacs Lake. Vandergoot is a key member of the international team that co-manages a very significant walleye fishery in Lake Erie. He works for the U.S. Geological Survey in the Sandusky Lake Erie Biological station in Ohio. His review report will be available to the public in early 2018 and will help inform fisheries management decisions for the 2018 season.
Q: What does the future look like for Mille Lacs walleye?
A: It is unlikely that Mille Lacs walleye production will return to the levels that state anglers enjoyed over 20 years ago. The ecosystem of Mille Lacs is going through extreme change, starting with increased water clarity in the mid-1990s, to impacts today from aquatic invasive species such as spiny water flea and zebra mussels. Longer growing seasons are also helping some species such as smallmouth bass but may be hurting others. While walleye will still be abundant, the future fishery will be more diverse, offering angling opportunities for a greater variety of fish.
