We caught several milting walleyes this past weekend…in water as warm as 58 degrees. Is that unusual for mid-May and water temps that warm?? We sure thought it was odd.
I would guess that you’re seeing late spawners just because the water has warmed so quickly in the last two weeks. I would also guess that those late spawners aren’t as late as they seem. Surface temps have warmed dramatically but the temp a couple feet down is far cooler than the what the graph says right now.
