equations were used to determine the approximate amount of
seepage from the aquifer:
 Q1 + Q2 = Q
 33Q1 + 167Q2 = CQ
 where, Q1 is the component of discharge from nonartesian
 aquifer and from direct runoff
 Qs is the component of discharge from Floridan
 aquifer
 Q is total discharge of Horse Creek
 C is mineral content of water of Horse Creek
 33 is average mineral content of ppm of typical water
 from nonartesian and from direct runoff
 167 is average mineral content in ppm of typical water
 from the Floridan aquifer.
Based on the computation, seepage from the Floridan aquifer
averaged about 6 cfs for the 4 complete months of daily conductivity
records.
 Color of water in Horse Creek ranged from 60 to 160 units and
the pH ranged from 6.4 to 7.4 units.
 Mineral content of water from Reedy Creek during a wet period
 in 1959 was 33 ppm, the color 80 units, and the pH 6.0 units.


 PEACE RIVER BASIN

 RELATION TO GREEN SWAMP AREA

 The Peace River basin lies immediately to the south of the
 designated boundary for the Green Swamp area. Before construc-
 tion of levees, highway and railroad fills, ditches and other drainage
 improvements, Lake Lowery and the surrounding marsh apparently
 drained southward into Peace River as well as northward to the
 Palatlakaha Creek and the Withlacoochee River basins. Under
 present conditions, the surface runoff from only 7 square miles of
 the Green Swamp area drains southward into the Peace River basin.
 This small area includes Gum Lake and its marsh outlet and Lake
 Alfred. The headwaters of the Peace River basin lie immediately
 south of the highest artesian water levels in the southeastern
 part of the Green Swamp area. Piezometric maps in figures 35 and
 36 indicate ground-water movement southward to the Peace River
 basin.
