Here in NC the weather has also been a little shifty. I believe the water temp. has to remain above 60 for a large spawn to occur. All fish do not spawn at the same time under optimum conditions. We have creeks where the water temp is now 67 and others where the temp is 59 in the morning and just 62 in the afternoon. Crappie are still spawning in those creeks.
