6.1.3 Gated Culverts

6.1.3.1 S-601 Gated Culvert Structure

The structure is the 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-601 is a two barreled, gated box culvert structure. The design flow is

2,000 cfs with a design head of 3.5 feet. The culvert barrels are typical box

culverts with dimensions of 10 feet in height, 10 feet in width and 200 feet in

length. The barrel invert is set at elevation –1.0 ft-NGVD. The structure will

discharge into an outlet channel and into the North New River Canal via the

existing bridge that serves the G-370 pump station.

6.1.3.2 S-602 and S-603 Gated Culvert Structures

These structures are the outlet for Cell 1 into STA 3/4. S-602 and S-603 are four

barreled, gated box culvert structures. The design flow is 3,000 cfs with a design

head of 2.5 feet. The culvert barrels are typical box culverts with dimensions of

10 feet in height, 10 feet in width and 200 feet in length. The barrel invert is set

at elevation 1.0 ft-NGVD. S-602 and S-603 are located on the southern Cell 1

levee just north of the STA 3/4 supply canal. The structures will discharge into

the STA 3/4 supply canal and then into STA 3/4 via existing gated structures G-

374 A-F, G-377 A-E and G-380 A-F.

6.1.3.3 S-604 Gated Culvert Structure

The structure is an interior bi-directional structure that hydraulically connects

reservoir Cells 1 and 2. S-604 is a three barreled, gated box culvert structure.

The design flow is 2,000 cfs with a design head of 2 feet. The culvert barrels are

typical box culverts with dimensions of 10 feet in height, 10 feet in width and

200 feet in length. The barrel invert is set at elevation 0.0 ft-NGVD. S-604 is

located in the internal reservoir levee (L-601i) between Cells 1 and 2.

6.1.3.4 S-605 Gated Culvert Structure

The structure is an inlet structure from North New River Canal into Cell 1.

Pump Station G-370 will pump from North New River Canal into a ring levee.

When the stage in the ring levee is sufficient for making discharges, the gates

from S-605 will be opened to release flows into Cell 1. S-605 is a three barreled,

gated box culvert structure. The design flow is 2,000 cfs with a design head of 1.5

feet. The culvert barrels are typical box culverts with dimensions of 10 feet in

height, 10 feet in width and 200 feet in length. The barrel invert is set at

elevation 0.0 ft-NGVD. S-605 is located in the ring levee near the south eastern

corner of Cell 1.
