S-333N Canal Gate Structure

Advanced Two-Gate Spillway Project Enhances Water Flow, Preserves Ecosystems, and Supports Everglades Restoration for a Sustainable Future

This project was the construction a fully automated, electrically operated two-gate spillway with design capacity of 1,150 cfs, providing additional operational flexibility and conveyance of flows to Everglades National Park (ENP) as a part of the Comprehensive Everglades Restoration Plan.

Being able to move more water south helps protect the surrounding wetlands, while providing relief to Lake Okeechobee.

The work involved construction of the new spillway with associated canal excavation, levee construction and stabilization, and a new air boat ramp, sidewalks, pavement, control building with instrumentation, motor operators, telemetry, site lighting, underground propane tank, and electric service conduit with associated horizontal directional drill under the L-29 canal.

A new water quality monitoring station was also installed.
