Here's a look at this summer's flows down the Caloosahatchee.
Unlike last summer, this year's flows are notably lower.
This hydrograph shows freshwater flows down the S-79 W.P. Franklin spillway. The horizontal green band indicates the ecologically desirable range of flows, from 300 to 2,800 cubic feet per second (cfs). Blue and especially black are the too high flow range and orange and especially red is when saltwater intrusion is most likely to occur. Currently the Caloosahatchee is in the desirable green zone.
That helps keep the estuary's brackish waters in balance.
