Though many have experienced warmer than normal temperatures, low lake temperatures in Minnesota have caused slow fish spawning. After the lakes iced this winter, temperatures have remained at or below average temperatures, meaning fish such as walleye and perch are slow to spawn this season.

Long term effects could include a gap in the fish age populations, reducing numbers and making for poor fishing conditions for anglers.
