My guess would be that the actual spawn does not occur in each particular spawn area until the water temp is 62/64 at the bottom whether 2' or 8' of water. I would also guess that during the early spawn, those trying to spawn when the water is first trying to get into the 63 degree range are chased off the beds very easily from a mild cold front. I would conclude from my guesswork that we should be taking water temps at or near the bottom of the spawn areas. If we find the temps slightly below the 62/64 degree range but no fish I would suspect we should pull off the bedding areas and try looking for suspended fish over deeper water but holding within the water column in their comfort range. I would guess trying somewhere in the mid 50's range might be the trick. What do you all say.
