distribution of runoff from the area. are shown in this table. The
years 1959 and 1960 were the wettest of record and 1961 and 1962
were the driest.
 The discharges given in table 15 indicate that Little Creek and
Withlacoochee-Hillsborough overflow carry significant amounts of
water from the area only in wet years. During 1961, Little Creek
carried only 0.9 percent and the Withlacoochee-Hillsborough
overflow carried only 0.2 percent of the total surface outflow from
the area. Both channels were dry during most months in 1961 and
1962.
 Ground-water outflow (U) from the Polk high was also
computed using the flow net method of analysis of the piezometric
