FIGURE 6.-Streams of northern and central Florida and their flow.
Where known from measurements, average flow of the streams is indicated by the symbols-a dotted line for flow less than 500 cfs (cubic feet a second), a solid line for each 500 cfs of flow in the larger streams. For example, the flow of the Suwannee River below the Santa Fe River is about 8,000 cfs. Flow is not measured in numerous long.reaches of certain streams, and cannot be shown here.
