DNR fish survey, 2025
A survey targeting age-0 Walleyes was conducted at Madison Lake on 30 October 2025 using 90 minutes of standard boat electrofishing. No age-0 Walleyes were sampled for a catch rate of 0.0/hour on-time for the second year in a row. The mean catch rate since 2003 during fry stocked years (n=11) was 31.8/per hour on-time while non-stocked years (n=7) have averaged 16.3/hour on-time. Natural reproduction has been poor since 2015 while fry stockings in 2016, 2021, and 2022 have produced moderate numbers.
