Description: This is a map showing water quality of Florida springs, current to 1979. First magnitude springs where the average flow is greater than 100 cubic feet per second are the ones with a larger circle with a little circle inside of it and they are pink, yellow and green. The second magnitude springs where the average flow is 10-100 cubic feet per second are the small circles that are pink, yellow, green and dark blue. Please see the article Water Quality of Florida Springs by Larry J. Slack and Jack C. Roseneau for more information.
