Waterway stage

This clearance is referred to a stage of the waterway itself, not to a tidal datum. Wind, rain and the level the Corps holds change what is really there.

“referred to a St. Lucie Canal stage of 14.5 feet”

“U.S. Route 98–441 highway bridge at Mile 38.8 has a fixed span with a clearance of 55 feet.”
NOAA U.S. Coast Pilot 4, 2026 (58th) Edition, Chapter 12 – Intracoastal Waterway

Datum

Coast Pilot 4, under the heading “Heights”: “Overhead clearances on the St. Lucie Canal from St. Lucie Lock to Port Mayaca Lock are referred to a St. Lucie Canal stage of 14.5 feet.” The figure is therefore not referred to a tidal datum.

Still east of the lock

Coast Pilot 4 puts Port Mayaca Lock about 300 yards west-southwest of this bridge, so it stands inside the reach whose clearances are referred to the canal stage.
