The flow of streams varies daily, seasonally, and from year to
year, depending upon the weather and climate. Because of these
variations, determination of a fairly reliable average flow requires
at least a 5 year record of flow. The degree of reliability of the
average increases with the length of record used; about 30 years
of record is considered sufficient for most natural streams.
In Florida a major stream (as used in this study) is one that
has an average flow of at least 1,000 cfs (cubic feet per second),
equivalent to 646 mgd (million gallons a day) or 1,983 acre-feet
a day. Defined thusly and based on estimated flows at mouths or
outlets, Florida has 11 major streams.
The average flow of major streams in Florida is shown on the
attached map by the blue overprint. Average flow is for the
period of record prior to September 30, 1967, which is generally
25 or more years for each stream. The flow of some smaller
streams is also shown in order to better portray the areal range
of average flow. Flows of the larger canals in southern Florida
also have been depicted, though usually the canals are not
classed as streams, and their flow is regulated.
The average flow of a stream depends on size of drainage
basin, topography, climate, geology, and land development. In
general, the drainage basins in northern Florida are large
compared with those in southern Florida; topographic relief is
greater, evaporation rate is lower, lakes are fewer, and the land is
developed to a lesser degree. In general, therefore, average flow
of streams in northern Florida is greater than that for streams in
southern Florida. Four of Florida's five largest streams are in
northern Florida. They are the Apalachicola, Suwannee,
Choctawhatchee, and Escambia Rivers. The third largest stream,
the St. Johns River, drains both southern and northern Florida.
Except for the St. Johns River, all five of the largest rivers derive
flow from beyond the borders of Florida.
Florida's largest stream, the Apalachicola River, is formed by
the confluence of the Flint and Chattahoochee Rivers at the
Georgia-Florida line. The Apalachicola River drains 19,600
square miles, of which 17,200 square miles are in Alabama and
Georgia and 2,400 square miles in Florida. At the Florida line
the average flow of the Apalachicola River is 22,000 cubic feet
per second, or about 14,000 mgd. Jim Woodruff Dam, at the
Georgia-Florida line, impounds the river to form Lake Seminole
(about 37,500 acres). Other large reservoirs upstream include
Lake Sidney Lanier and Lake Harding in Georgia. At the Gulf of
Mexico the average flow of the Apalachicola River is about
16,000 mgd.
The Chipola River is the largest of the Florida tributaries to
the Apalachicola River. The average flow of the Chipola River
near Altha is 980 mgd.
The Suwannee River, which drains about 10,000 square miles,
is the second largest river in Florida. The Suwannee River heads
in the Okefenoke Swamp of southern Georgia and flows
southward to the Gulf of Mexico. At the Georgia-Florida line the
flow averages about 1,000 mgd and increases rapidly
downstream because of contributions from the numerous
springs. The Suwannee River has two main tributaries, the
Withlacoochee and the Santa Fe Rivers. The Withlacoochee
River drains about 2,300 square miles in Florida and southern
Georgia and adds about 1,100 mgd to the flow of the Suwannee.
The Santa Fe River drains about 1,600 square miles in northern
Florida and adds about 1,500 mgd. The Santa Fe River is
unusual because the river enters the ground near Oleno State
Park and emerges about three miles downstream to continue its
course as a surface stream. The average flow of the Suwannee
River, at its mouth, is about 11,000 mgd.
Large springs that flow into the Suwannee River or its
tributaries include White Springs, Suwannee Springs, Troy
Spring, Ichatucknee Spring, Rock Bluff Spring, Fannin Spring,
and Manatee Spring. Four of these springs- Troy, Ichatucknee,
Fannin and Manatee, are first magnitude springs with flows
averaging at least 100 mgd, and together discharge an average of
about 500 mgd to the Suwannee.
The St. Johns River, the third largest river in the state, heads
in the marshes west of Vero Beach and meanders northward 275
miles, roughly paralleling the east coast and flowing into the
