Point of View: Commercial, lawn pumping drying up Florida's springs

Published May 20, 2012 Florida Times-Union
The absence of normal rainfall in north central Florida has revealed an inconvenient truth — there is little water left in the aquifer to maintain the baseflow of our springs. As long as we have average rainfall, the springs keep flowing and it is easier to believe that long-term flow declines in our springs are just a response to a variable rainfall cycle.

But strip away normal rain and what is left? The lowest flows ever recorded in Silver and Rainbow springs, just to mention two of the most famous springs in the state.

Beginning in 1985, Silver Springs’ average annual flow began to decline at a faster rate than the flow at Rainbow Springs. As a consequence of this accelerated flow decline, in 1998 Silver Springs lost its dominance over Rainbow Springs.
