		Lakebed sediment characterization was one of the primary tasks of the USGS Lake Pontchartrain study.
		In Lake Pontchartrain, 757 surface sediment samples were collected on a 1.2 km (0.75 mi) grid (Figure 97) and were analyzed by x-ray fluorescence spectroscopy (XRF) for bulk metals concentration.
		At seven sampling stations along the Lake Pontchartrain Causeway, the average total suspended sediment concentration peaked at approximately 70 mg/l during the Spillway opening and the total mass of sediment discharged into the Lake was approximately 7.1 x 108 kg (780,000 US tons).

		The Lake Pontchartrain Causeway is spelled that way because that's what it is -- a causeway.
		By definition, a causeway is a road formed on a "causey" or mound, a raised road across a low or wet place or body of water.
		One famous causeway is the Giant's Causeway, which is a natural formation in County Antrim on the northern coast of Ireland.

	Comments on: The Lake Pontchartrain Causeway
		The Causeway began as a single two-way bridge in the mid 1950s (1955, I think), and then, years later, a second bridge was built.
		As was mentioned previously, the lake is relatively shallow.
		Lake Pontrhartrain is relatively shallow (about 28' on average, I believe) so there is no suspension section.
