How long does the spawn last when they start? Looking to plan my vacation for the spawn.
That's a lie! I got 2 last year on April 6th! HahahaView attachment 203815 Spring Walleye Spawning Map
Very likely due to variations in the water temperatures. This time of year, our lakes don't warm at the same rate. Bars that are shaded from the sun much of the day, or adjacent to deeper water, will not warm as fast as areas that don't get a lot of wind but do get more sun hours during the day. This brings another factor into play, checking for the magic 42 degree spawning temperature where you're fishing! The males will show up cruising for females at 40 degrees.(Study done by Minn. Fisheries biologists-not by me!)The males start showing up first on the gravel bars. Should be a few on them now.
For the walleye spawn don't just try one gravel area and make that your judgment for the entire lake. Some days certain spots produce when others won't. So search around.
