Lake survey information

Throughout the current field season we will be posting preliminary results, or quick summaries of lake surveys we are conducting. Ice-out Assessments are performed with trap nets while standard Lake Surveys are with both gill and trap nets. Catches of species from standard lake surveys are shown for the indicator gear. For example: Northern Pike (NOP), Walleye (WAE), and Yellow Perch (YEP) are best sampled with gill nets, while Black Crappie (BLC) and Bluegill (BLG) are best sampled with trap nets. Please feel free to contact our office with any specific questions you may have. We will be glad to help you. E-mail Lake Survey Specialist.
