20-Year Aquifer High

Hydrographers at the District have found that flows at some Floridan Aquifer springs on the lower Santa Fe River are running higher than they have for the last 20 years. “This is what we would expect, based on the observed high Floridan Aquifer levels in springs contributing areas in Columbia and Alachua counties,” says Deputy Executive Director Tom Mirti.

Flow measured at Hornsby and Treehouse Springs in late August was at its highest since 1998, when a very wet autumn and winter in 1997 saturated the aquifer. Treehouse Spring is fed by a swallet downstream of Hornsby Spring as well as other sources of both groundwater and surface water. At Poe and Gilchrist Blue springs, flows are continuing to increase as they have since 2012.
