The survey is Fish populations can fluctuate due to conducted during the open season for natural forces like weather, predation or gamefish from the first Saturday in May competition; management actions like through the first Sunday in March. Creel stocking, regulations or habitat surveys are not conducted in November improvement; habitat loss and harvest when fishing effort is low and ice conditions impacts. Wisconsin Department of Natural are often unsafe. The survey is run during Resources fisheries crews regularly conduct daylight hours, and shift times change from fishery surveys on lakes and reservoirs to month to month as day length changes. gather the information needed to monitor changes, identify concerns, evaluate past Creel survey clerks travel their lakes management actions, and to prescribe using a boat or snowmobile to count the fishery management strategies. Netting and number of anglers at predetermined times, electrofishing surveys are used to gather and to interview anglers who have data on the status of fish populations and completed their fishing trip. Data is communities, measuring such parameters as collected on what species they fished for, species composition, population size, catch, harvest, lengths of fish harvested, reproductive success, size or age distribution marks (fin clips or tags), and hours of and growth rates. The other key component fishing effort. Collecting completed-trip of the fishery that we often need to measure data provides the most accurate assessment is harvest. of angling activities, and it avoids the need to disturb anglers while they are fishing.

Number of Angler Party Interviews is the number of groups of anglers interviewed by the creel clerk. A party is considered the members of a group who fish together in the same boat, ice shanty, or from shore. The clerk fills out one interview form for each group of anglers. The number of individual anglers actually contacted by the clerk is usually much greater than the number of groups listed in this table since most groups consist of more than one angler.

Total Angler Hours is the estimated total number of hours that anglers spent fishing on Madeline Lake 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 in order to compare effort on Madeline Lake to other lakes.

2005-06 Total Angler Hours/Acre is the total angler hours divided by the area of the lake in acres. This is from the previous creel survey that took place on Madeline Lake.

County Average Hours/Acre is the average angler effort in hours per acre for county lakes that have been surveyed since 1990. This value is useful for fishing pressure comparisons with other waters.

Ceded Territory Average Hours/Acre is the average angler effort in hours per acre for inland lakes in the Ceded Territory that have been surveyed since 1990. This value can be used to compare Madeline Lake to other lakes in northern Wisconsin.
