The last trip that I took at the North River was February 1st and we did well but we caught very few females. Some of the ones that I caught were pushing eggs out. AND ALL the males were shooting everywhere! There is probably a few still around though..... but id have to agree with REDBOAT the ice will probably be a problem on Saturday. Im hoping it will be gone by Sunday to fish the crappie tournament at NWR. Good Luck when you decide to go!
