DRAFT
Duration of salinity incursions greater than or equal to 5 ppt or 10 ppt
at the data recorder in upper spring run for 1 cfs flow classes from
Sulphur Springs............................................................................... 5-15
Relation between 15-minute values for water levels in the Lower
Hillsborough River near the mouth of the spring and salinity at the data
recorder in the upper spring run ...................................................... 5-17
Relationships between daily mean, maximum, and minimum water
levels in the upper spring run and flow from Sulphur Springs
pool.................................................................................................. 5-19
Box and whisker plot of daily minimum water levels in the upper spring
run in 1 cfs flow classes from Sulphur Springs pool ........................ 5-20
Box and whisker plot of 15 minute salinity measurements at the data
recorder at the mouth of the spring run. Data restricted to periods when
there was no flow to the lower river from the Hillsborough River
reservoir .......................................................................................... 5-22
Two-dimensional plot of salinity distributions for inflows of 0 cfs of
springwater at the dam and 31 cfs of springflow at Sulphur
Springs ............................................................................................ 5-26
Two-dimensional plot of salinity distributions for inflows of 10 cfs of
springwater at the dam and 21 cfs of springflow at Sulphur
Springs ............................................................................................ 5-26
Two-dimensional plot of salinity distributions for inflows of 10 cfs of
springwater at the dam and 21 cfs of springflow at Sulphur Springs.
(Scenario 6)..................................................................................... 5-28
Two-dimensional plot of salinity distributions for inflows of 10 cfs of
springwater at the dam and 13 cfs of springflow at Sulphur Springs.
(Scenario 7)..................................................................................... 5-28

springwater at the dam and 10 cfs of springflow at Sulphur Springs.
(Scenario 8)..................................................................................... 5-29
Two-dimensional plot of salinity distributions for inflows of 13 cfs of
springwater at the dam and 18 cfs of springflow at Sulphur Springs.
(Scenario 9)..................................................................................... 5-29
Two-dimensional plot of salinity distributions for inflows of 18 cfs of
springwater at the dam and 13 cfs of springflow at Sulphur Springs.
(Scenario 10)................................................................................... 5-31
Two-dimensional plot of salinity distributions for inflows of 21 cfs of
springwater at the dam and 10 cfs of springflow at Sulphur Springs.
(Scenario 11)................................................................................... 5-31
Two-dimensional plot of salinity distributions for inflows of 10 cfs of
springwater at the dam and 18 to 10 cfs of springflow at Sulphur
Springs, switching when stage in the river goes above or below 0 feet
NGVD. (Scenario 12)....................................................................... 5-33
Two-dimensional plot of salinity distributions for inflows of 13 cfs of
springwater at the dam and 18 cfs of springflow at Sulphur Springs
when levels in river above 0.0 feet; switching to 21 cfs at the dam and
10 cfs at Sulphur Springs when river stage goes below 0 feet NGVD.
