I find the use of the term "strait" in relation to the Rigolets to be interesting.  Although definitions vary, I think of a strait as being a relatively shallow passage between two deeper, larger bodies of water.  A pass, on the other hand, can be a deep-water passage between two relatively shallow bodies.  This is the case with the Rigolets, a prehistoric Mississippi River channel now connecting shallow Lakes Pontchartrain and Borgne.  At one point in the 1980s the NOAA chartmakers considered labelling the Rigolets as "Rigolets Pass."
