INTRODUCTION Fish populations can fluctuate due to natural forces (weather, predation, competition), management actions (stocking, regulations, habitat improvement), inappropriate development (habitat degradation), and harvest impacts. Wisconsin Department of Natural Resources fisheries crews regularly conduct fishery surveys on area lakes and reservoirs to gather the information needed to monitor changes, identify concerns, evaluate past management actions, and to prescribe good fishery management strategies. Netting and electrofishing surveys are used to gather data on the status of fish populations and communities (species composition, population size, reproductive success, size/age distribution, and growth rates). But the other key component of the fishery that we often need to measure is the harvest. On many lakes in the Ceded Territory of northern Wisconsin, harvest of fish is divided between sport anglers and the six Chippewa tribes who harvest fish under rights granted by federal treaties. The tribes harvest fish mostly using a highly efficient method, spearing, during a relatively short time period in the spring. Every fish in the spear harvest is counted – a complete “census” of the harvest. We also measure the sport harvest to assess its impact on the fishery. But because it would be highly impractical and very costly to conduct a complete census of every angler who fishes on a lake, we conduct creel surveys. A creel survey is an assessment tool used to sample the fishing activities of anglers on a body of water and make projections of harvest and other fishery parameters. Creel survey clerks work on randomly-selected

days and shifts, forty hours per week during the open season for gamefish from the first Saturday in May through the first Sunday in March, except during the month of November when fishing effort is low and ice conditions are often unsafe. The survey is run during daylight hours, and shift times change from month to month as day length changes. Creel survey clerks travel their lakes using a boat or snowmobile to count numbers of anglers on a lake at predetermined times, and to interview anglers who have completed their fishing trip to collect data on what species they fished for, catch, harvest, lengths of fish harvested, marks (finclips or tags), and hours of fishing effort. Collecting completed-trip data provides the most accurate assessment of angling activities, and it avoids the need to disturb anglers while they are fishing. A computer program is used to make projections of total catch and harvest of each species, catch and harvest rates, and total fishing effort, by month and for the year in total. Keep in mind that these are only projections based on the best information available, and not a complete accounting of effort, catch, and harvest. Accurate projections require that we sample a sufficient and representative portion of the angling activity on a lake. The accuracy of creel survey results, therefore, depends on good cooperation and truthful responses by anglers when a creel clerk interviews them. You may have encountered a DNR creel survey clerk on a recent fishing trip. We appreciate your cooperation during an interview. The survey only takes a moment of your time and it gives the Department valuable information needed for management of the fishery.

This report provides projections of: 1. Overall fishing effort (pressure) 2. Fishing effort directed at each species 3. Catch and harvest rates 4. Numbers of fish caught and harvested Also included are a physical description of Presque Isle Chain; discussion of results of the survey; and detailed summaries, by species of fishing effort, catch and harvest. GENERAL LAKE INFORMATION

Location Presque Isle Chain is located in Vilas County in the Town of Presque Isle. Physical Characteristics Presque Isle Chain is a 1,571 acre chain with a total of three lakes (Averill, Presque Isle, and Van Vliet).Littoral substrate consists primarily of sand, with lesser amounts of muck, and gravel. Presque Isle Chain is a soft water drainage lake with slightly acidic, clear water of moderate transparency. Seasons Surveyed The period referred to in this report as the 2012-13 fishing season ran from May 5, 2012 through March 3, 2013. The open water creel survey ran from May 5 through October 31, 2012 and the ice fishing creel survey ran from December 1, 2012 through March 3, 2013.

Weather Ice-out on Presque Isle Chain was around March 25, 2012. Fishable-ice formed on Presque Isle Chain in mid-December. Sportfishing Regulations The following seasons, daily bag limits, and length limits were in place on Presque Isle Chain during the 2012-13fishing season:

walleye, but due to tribal declarations it was reduced on Presque Isle Chain.

SPECIES CATCH AND HARVEST INFORMATION Angling effort, catch, and harvest information is summarized for each species in Table 2 and Figures 1-10. Table 2 also includes a comparison of these statistics with the previous creel survey. Information presented about species whose fishing season extends beyond March _ should be considered minimum estimates. Each species page has up to five graphs depicting the following: 1. PROJECTED FISHING EFFORT Total calculated number of hours

during each month that anglers spent fishing for a species.

2. PROJECTED SPECIFIC CATCH

AND HARVEST RATES Calculated number of hours it takes

an angler to catch or harvest a fish of the indicated species. Only information from anglers who were

specifically targeting that species is reported.

3. PROJECTED CATCH AND

HARVEST Calculated number of fish of the

indicated species caught or harvested by all anglers, regardless of targeted species.

4. LENGTH DISTRIBUTION OF

HARVESTED FISH All fish of a species that were

measured by the clerk during the entire creel survey season.

5. LARGEST AND AVERAGE

LENGTH OF HARVESTED FISH Monthly largest and average length

of harvested fish of a species. Only those fish measured by the creel survey clerk are reported.

CREEL SURVEY RESULTS AND DISCUSSION Survey Logistics The creel survey went well. We encountered no unusual problems conducting the survey or calculating the projections contained in the report. This was the second time the department conducted a creel survey on Presque Isle Chain. The last creel survey of the Presque Isle Chain took place in 1992-93. General Angler Information Anglers spent 23,021 hours or 14.7 hours per acre fishing Presque Isle Chain during the 2012-13 fishing season (Table 1). That was less than the Vilas County average of 34.6 hours per acre. July was the most heavily fished month (2.8 hours per acre). Fishing effort was lightest in December (0.4 hours per acre) for those months when the

entire month was creeled. RESULTS BY SPECIES Walleye (Table 2, Figure 1) Fishing effort directed at walleye was 4,304 hours during the 2012-13 fishing season. The greatest fishing effort for walleyes was in July (1,164 hours). January had the least amount of walleye fishing effort (45 hours) for a full month creeled. Total catch of walleyes was 1,435 fish with a harvest of 318 fish. Highest catch (481 fish) occurred in May and harvest (77 fish) occurred in October. Anglers fished 3.1 hours to catch and 14.2 hours to harvest a walleyes during 2012-13. The mean length of harvested walleyes was 15.1 inches and the largest walleye measured was a 22.1 inch fish caught on Presque Isle Lake. Northern Pike (Table 2, Figure 2) Fishing effort directed at northern pike was 4,299 hours during the 2012-13 fishing season. Northern pike fishing effort was greatest in July (1,132 hours). Total catch of northern pike was 3,646 fish with a harvest of 669 fish. The mean length of harvested northern pike was 19.8 inches and the largest northern pike measured was a 28 inch fish caught on Van Vliet Lake. Muskellunge (Table 2, Figure 3) Muskellunge received the most fishing effort during the 2012-13 fishing season. Anglers spent 8,006 hours targeting muskellunge. Muskellunge fishing effort was greatest in September (1,959 hours).

4

Total catch of muskellunge was 208 fish. Highest catch (59 fish) occurred in June. Anglers fished 44.5 hours to catch a muskellunge during 2012-13 Smallmouth Bass (Table 2, Figure 4) Fishing effort targeted at smallmouth bass was 1,935 hours during the 2012-13 fishing season. Smallmouth bass fishing effort was greatest in May (690 hours). Total catch of smallmouth bass was 1,300 fish with 13 harvested. Highest catch (373 fish) occurred in May. Anglers fished 2.4 hours to catch a smallmouth bass during 2012-13. Largemouth Bass (Table 2, Figure 5) Fishing effort directed at largemouth bass was 1,498 hours during the 2012-13 fishing season. Largemouth bass fishing effort was greatest in July (750 hours). Total catch of largemouth bass was 833 fish with a harvest of 4 fish. Highest catch (306 fish) occurred in June. Anglers fished 2.8 hours to catch a largemouth bass during 2012-13. Panfish (Table 2, Figures 6-10) Black crappies were the most sought after panfish species during the survey. Fishing effort directed at black crappies was 5,263 hours. Anglers caught 6,096 black crappies and harvested 1,699 fish. The mean length of black crappies harvested was 9.4 inches. Bluegills were the second most sought after panfish species during the survey. Fishing effort directed at bluegills was 5,008 hours. Total catch of bluegills was 16,318 fish with 2,891 harvested. The mean length of bluegills harvested was 7.2 inches.

Yellow perch were the third most sought after panfish species during the survey. Fishing effort directed at yellow perch was 4,763 hours. Total catch of yellow perch was 9,479 fish with 2,423 harvested. The mean length of yellow perch harvested was 8.7 inches. Pumpkinseeds and rock bass were also caught during the 2012-13 season. ACKNOWLEDGMENTS Completion of this survey was possible because of the efforts of the technical staff of the fisheries management and Treaty Fisheries Unit. Treaty staff responsible for ensuring completion of this survey included Jonathan Pyatskowit, Jeff Blonski, Joelle Underwood, Marty Kiepke, Jason Halverson, and Tim Tobias. Marty Kiepke was the creel clerk on Presque Isle Chain during the survey period. We also thank all the anglers who took the time to offer information about their fishing trip to the survey clerk. Without their cooperation the survey would not have been possible. The department thanks the cooperators, Tim, Kim, and Cameil Bowler of Alpine Resort who generously allowed the department to keep a boat and snowmobile on their property during this survey. This creel report was reviewed by, Steve Gilbert and Dennis Scholl of the Wisconsin Department of Natural Resources, Woodruff, Wisconsin.

*"Summer" is May-October; "Winter" is December-March**Too few lakes have been surveyed in March to give a meaningful statewide average.

Statewide Average Hours/Acre is the average angler effort in hours per acre for inland lakes in the state surveyed between 1990 and 1995. This value can be used to compare the Presque Isle Chain to other lakes statewide.

Total Angler Hours is the estimated total number of hours that anglers spent fishing on the Presque Isle Chain during each month surveyed.

Total Angler Hours/Acre is the total angler hours divided by the area of the lake in acres. This is useful if you wish to compare effort on the Presque Isle Chain to other lakes.

County Average Hours/Acre is the average angler effort in hours per acre for county lakes that have been surveyed since 1990. This value can be useful in comparisons as well.
