How to reach:
To reach the tidal bench marks by boat from Rigaud Marina at the east end of Grand Isle, proceed north along Barataria Bay Waterway for 26 km (16 mi) to the Manila Village Oil Field, then continue on the waterway for 1.6 km (1.0 mi) past the oil field on the right, then veer left into Bayou St. Denis and follow the channel into the dredged slip on the north side of the bayou to M.V. Petroleum Dock. The bench marks are located along the spoil banks surrounding the slip and clockwise around the slip from the dock. The tide gage and staff were located on the NW side of the northernmost platform and concrete deck supporting Storage Tank #52246 in the M.V. Petroleum Dock complex.
