The level to which water will rise in a tightly cased ( sealed) well is known as the potentiometric surface. In 1948, water levels in wells in the upper Floridan aquifer were 40 to 65 Fort Walton area, and many wells flowed naturally. Subsequent withdrawal from the aquifer, The Fort water levels in its wells monthly since 1978. The water levels in 2007 were an they were thirty years ago.
