Fla. Admin. Code Ann. R. 40CER17-01 - Minimum Flows for Silver Springs

The following minimum surface water flows and levels are established for Silver Springs in Marion County, as measured at the USGS 02239501 gaging station:

Minimum Flows	Flow (cfs)	Level (NAVD)	Duration (days)	Return Interval (years)
Frequent high	828	40.0	30	5
Average	638	38.2	180	1.7
Frequent low	572	37.0	120	3

The minimum surface water flows were developed to ensure that the associated surface water levels will be met. The two factors to be weighed in the status assessment of this MFL are (1) whether the surface water levels have been met and (2) the extent to which the surface water flow has been reduced due to groundwater withdrawals.
