There was a good crappie bite on the American side last spring and fall but crappie fishing from year to year is consistently better on the Canadian side primarily for one reason. Black Bay is the one primary area where they spawn on the American side with a few other small shallow bays being occasional secondary areas. All of these are along the south shore and exposed to the effects of any wind out of the north that will bring in cold water off the main lake and can drop water temps by 10 or more degrees in 24 hours which really takes a toll on the success of the spawn. Consequently we have 1-3 good spawning years out of 10. The harvest in 08 was mostly a result of 1 good year class with another good year class being around 8-9″. However the crappies harvested in 08 were, for most anglers, non-existent in 07 and before. Apparently there was a desirable, concentrated food source that attracted them last year. Whether that will happen this year remains to be seen. Not trying to discourage you or drive business away but it is the way it is.
The 70% of Rainy north of the border has some huge bays with good spawning habitat that are better protected from north winds. One downside imo is commercial netting of crappies still takes place in Canadian waters.
Now the disclaimer: one thing that would improve your chances of a good bite in American waters in any given year is having Rainydaze in the boat. Chris is on the water a lot, a dedicated slab chaser (not in the “most anglers” noted above) and if there’s a good bite on he won’t be far away ….. unless monster pike or walleyes with shoulders have distracted him.
