How to reach:
To reach the tidal bench marks from Hi Ridge Marina at the north side of Port Sulphur, proceed by boat SW in the marina canal to Grand Bayou, then turn left into Grand Bayou and proceed SE to the Freeport Sulphur Company Canal, then turn right into the canal and proceed SW to Rattlesnake Bayou, then turn left into the bayou (Rosewood Resources, Inc. Compressor Station is on the left) and proceed about 1.6 km (1.0 mi) to Robinson Canal, then turn right into the canal and proceed about 2.4 km (1.5 mi) to Billet Bay Community and the sheriff's camp with an American flag atop the camp. The bench marks are located in the vicinity of the sheriff's camp and SE along the marsh the camp is on. The tide gage and staff were located on the southernmost corner of the sheriff's wharf. Note: A recent fishing map available at Hi Ridge Marina is useful in finding this site.
