The Northern Highland Fishery Research Area
The Northern Highland Fishery Research Area (once called the Five Lakes Project) is an experimental project of the DNR which has been going on since 1946. It includes Escanaba, Nebish, Mystery, Spruce and Pallette Lakes, all located between Boulder Junction and Star Lake off of Highway K. Originally fishing was allowed on these lakes without regard to size or catch limits or season. In recent years the experiment has been changed and the fishing rules have changed. The rule noted below for Escanaba Lake (limit one walleye at least 28") began in 2003. Report 2012
There is a registration station of Escanaba Lake where fishers on any of the lakes must register and where they must register their catch.
There have been several research publications based on research at the Five Lakes Project. Those of which I am aware are listed in the Bibliography for this topic in the "Comprehensive" section. Popular articles are listed in the "Major" or "Minor" sections.
From the DNR website (2012):
Experimental Waters of the Northern Highlands Fishery Research Area: Escanaba, Mystery, Nebish, Pallette, and Spruce Lakes have been managed as experimental waters since 1946. Every fish taken is counted and measured as part of the longest continuous record of angler harvest in the world! A free daily fishing permit from the Escanaba Lake Research Station is required to fish on any of these five lakes. The research station is located three and one-half miles east of Trout Lake off of Highway M in Vilas County. A Wisconsin fishing license is also required.
The lakes are open to continuous year-round fishing for all species with exception(s) listed below by lake. These lakes are not open to fishing on New Year's Eve, New Year's Day, Martin Luther King Day, Christmas Eve and Christmas Day. The research station is open from 4 a.m. to 8-10 p.m. during open water season and 6 a.m. to 6-8 p.m. during ice fishing season. Closing hours vary depending on available daylight. After fishing, anglers must return the permit and bring their catch to be examined by biologists for entry into the database. For more information, contact: Wisconsin Department of Natural Resources, Northern Highland Fishery Research Area, 8770 Highway J, Woodruff, WI 54568, (715) 356-5211.
Escanaba Lake - The minimum length limit on walleye is 28" with a daily bag limit of 1.

The minimum length limit on smallmouth bass is 22" and the daily bag limit is 1. Spruce Lake - Only artificial flies and lures may be used. Largemouth bass season is open all year with a 12" minimum length limit and a daily bag limit of 2.

+++ONGOING RESEARCH 2009
From the University of Wisconsin Stevens Point, College of Natural Resources, Wisconsin Cooperative Fishery Research Unit ##1859 Annual Report##:
Fish population size, size structure, reproduction, and recruitment, are highly dynamic and often fluctuate widely across years. Such population variability, in combination with intensive harvest from state and tribal users greatly increases the risk of overexploitation and possible fishery collapse. Regulations offer opportunities not only to prevent population collapse, but to maximize different desirable fish population characteristics such as size structure (i.e., larger fish), abundance, and catch rates, among others that offer a wide array of angling opportunities. Studying the effects of regulation changes insure that desirable outcomes are achieved and elucidate under which conditions particular regulations should be implemented. The most effective way to measure the effects of natural population variability and regulation changes relative to exploitation is by studying them for a long period of time. There are at least eight different regulations that are applied to the management of walleye in northern Wisconsin with the intent of creating diverse fishing opportunities. Unfortunately, many of those regulations have not been evaluated. The Wisconsin Department of Natural Resources (then the Wisconsin Conservation Commission) established the Northern Highlands Fishery Research Area (NHFRA) in 1946 and the population size of walleye in Escanaba Lake has been estimated there annually since 1953. Until 2000, harvest of walleye was unlimited (no bag or size limits) and the population fluctuated annually. In 2000, as part of an overall exploitation study, a 28 inch minimum size limit was established to effectively reduce harvest to near zero and to help create a trophy walleye fishery. The objective of this study is to evaluate how walleye and other species of fish have responded (e.g., abundance, growth) to the implementation of the 28 inch minimum size limit using the long term data set available at Escanaba Lake.
