Executive Summary
Gated Culverts
The selected plan includes numerous gated culverts to facilitate the
management of water within the reservoir cells and to release water out of the
reservoir. S-601 is a 2,000 cfs outlet for Cell 1 into the North New River Canal
and is located near the southeastern corner of Cell 1 just north of the G-370
pump station. S-602 and S-603 are 3,000 cfs culvert structures located on the
southern Cell 1 levee and discharge into the STA 3/4 supply canal. S-604 is a
2,000 cfs culvert structure located in the internal reservoir levee (L-601i)
between Cells 1 and 2. S-604 is a 2,000 cfs culvert to provide flows between
Cells 1 and 2. S-605 is a 2,000 cfs inlet structure from North New River Canal,
via Pump Station G-370, into Cell 1. S-606 is a 2,000 cfs outlet structure from
Cell 1 to the STA 3/4 supply canal. S-607 is a 2,000 cfs outlet from Cell 2 to the
North New River Canal, via gated structure S-609. S-608 is a 2,000 cfs outlet
from Cell 2 into the Miami Canal. S-609 is a 2,000 cfs outlet from Cell 1 into the
North New River Canal.
Canals
The current design conveyance capacity of the Miami Canal of 3,000 cfs will be
increased by approximately 50% for an approximately 9 mile section of the canal.
The current design conveyance capacity of the North New River Canal of 4,000
cfs will be increased by approximately 150% for approximately 23 miles of the
canal between the reservoir and Lake Okeechobee. Improvements to the Bolles
and Cross Canals in order to allow water from Lake Okeechobee and the
northern portion of the EAA to be more effectively routed to the south require a
design capacity of 1,500 cfs. The increase in capacity requirements necessitated
an enlargement of the entire reach of the Bolles and Cross Canals totaling
approximately 17 miles. All of this canal work will be performed within the
existing SFWMD right-of-way
The functions of perimeter canals, C-601 and C-602, are for seepage collection
and conveyance of reservoir outlet flows. The seepage canals also serve as a
borrow source for construction of embankments. The new perimeter canals will
capture seepage at the western, northern, and eastern boundaries of the
reservoir. Seepage along the reservoir's southern boundary will be captured by
the existing STA 3/4 supply canal.
Embankments
The reservoir has perimeter embankments, L-601 and L-602, with a minimum
height of 23 feet above average ground. The height of the internal embankment
L-601i is 21 feet above average ground. Cut-off walls will be installed as part of
the embankment construction. The estimated depth of the cut-off wall is 35 feet
