Early walleye spawn?
Several factors combine to trigger the annual Spring walleye spawning run on the upper Mississippi River. Water temp, moon phase ,walleye belly status, River level and weather are all considerations which drive the timing of peak spawning activity.
Unseasonably warm weather just after ice out warmed surface temps to 47 degrees. ‘Eyes typically spawn at 45-48 degrees. Take a dozen eggs out of the freezer and throw them in a hot skillet. They won’t be ready to eat in 45 seconds!
47 degree water temp on march 14 have since cooled to a more seasonal 43 degrees. Over the past 25 years we usually see 43 degree water about April 5. Six years ago we had an early spring warm up. Walleyes were goin’ at it on April 1. Long term the average is about April 20.
Rapidly cooling water temp or rapid rise in river level caused by snowmelt can moderate the timing and pace of the spawn. Not a factor this year.
On the upper Miss, walleyes tend to ‘stairstep’ into shallower water as the spawn approached. At ice out you’ll find them in wintering holes–30+ fow. As of yesterday ‘active’ fish were in 22 fow–at least for me. The bite was a sheep-o-rama. Goats usually got to the jigs n blade baits first.
The walleye behavior pattern is not dialed in for me yet. They are clearly starting to move up the stairs. Given the variables of water temp, moon phase and firmness of female walleye bellies I THINK we may see serious walleye spawning by April 9.
Barring outrageous weather conditions like howling wind driven sleet storms I’m usually out there on the River about 5 days a week.
Blogging today cuz the weather outside is a howling beast. Probably won’t get out again til thursday afternoon. i’m not a great fisherman. don’t claim to be. Just out there and average of 175 days annually for the past 50 years or so.
26 year old kids with stiff necks from staring at live target sonar probably catch more fish. I never plan on owning this level of technology. Nothing to prove. Joy is from the River experience, not a box.
If i was a 26 year old kid again I would have live target sonar, an electric outboard and EV pickup truck. The long term weather trend is definitely global warming. yessiree, Bob. Good thing they took down the coal fired power plants At Genoa & Lansing. Much less air pollution now….
There is a fine line between a fishin’ blog and an old guy rant, so adios
