The water temperature that I listed is at the depth the bass are using or holding in. The surface temps are usually warmer and with spawning the activity starts at 62 to 65 and can continue for up to 3 full moon phases.
It's difficult to see color in black and white and the original chart is faded badly, like me. looking at the chart the horizon is at 3 & 9 o'clock out to the white circle and first color band. The colors on the first inner band and second band are @ 3-9 o'clock red indicating active, next is yellow indicating neutral and then blue indicating negative. the third color band starting at late winter and going clock wise; blue to fall, then yellow to summer, then blue summer days and yellow summer nights, then yellow spring, blue post spawn, yellow spawn and red pre spawn. Everything for the calendar period to the first color band working outside inward belongs to the segment, The next ring inside is a 24 hour ring, then the center ring is moon phase ring. Simple!! looking at it from my eyes. I know this is difficult stuff to understand, but it works within reasonable limits considering how accurate the water temp is measured, what I knew at the time and what type of bass you are applying it to. Florida's are a little different than the northern LMB that I based this on, close enough to get you in the right seasonal periods.
