Spring Classifications

Springs are classified by their Volume of Flow (Discharge) and are divided into eight classifications, with “First Magnitude” having the highest volume of flow. Gainer Springs is one of only 75 First Magnitude Springs in the United States and one of only 27 in the state of Florida.

SPRING CLASSIFICATIONS:

Magnitude Volume of Flow (Discharge)
1 100 cfs or more
2 10 to 100 cfs
3 1 to 10 cfs
4 0.223 cfs (100 gpm) to 1 cfs
5 0.0223 cfs (10 gpm) to 0.223 cfs
6 0.0022 cfs (1 gpm) to 0.0223 cfs
7 0.00028 cfs (1 pint/min) to 0.0022 cfs
8 0.00028 cfs or less

Units:
cfs = cubic feet per second
gpm = gallons per minute
pint/min = pints per minute

Conversions:
100 cfs = 64.6 million gallons per day
1 cfs = 646,316.9 gallons per day
1 gallons per minute = 0.0022 cfs
1 pint per minute = 0.00028 cfs
