The Wisconsin Department of Natural Resources (DNR) conducted a comprehensive survey of Blackhawk Lake in 2020. The primary focus of this survey was to estimate the abundance and size structure of Walleye and assess the relative abundance and size structure of other gamefish and panfish in the lake.

INTRODUCTION. Reliable long-term wildlife population trends are critical for making informed decisions on management of harvested species such as white-tailed deer (Odocoileus virginianus) and bobcat (Lynx rufus) and for monitoring the population status of rare or secretive species such as gray fox (Urocyon cinereoargenteus).
In 2019, we collected responses from 2,549 bow hunters (29% response rate) consisting of 25,681 hunting trips and 84,951 hours of total observation time (3.28 ± 0.028 hours/trip). With the exception of northwest Iowa, the total number of deer observations decreased between 2018 and 2019.
The primary objectives of this survey are to 1) collect observations of white-tailed deer which serve as an independent index of regional deer populations across the state, 2) supplement other deer data collected by the DNR, and 3) collect observations of other select species to monitor their long-term population trends.

The DNR produces a wide range of publications and information for the public on hundreds of topics related to the environment, recreation, wildlife, and natural resources. In many cases, no piece of information is quite as helpful as a good map!
