ポンチャートレイン湖
This report’s recommended protection plan for Lake Pontchartrain and Vicinity consisted of a barrier at the east end of Lake Pontchartrain. The barrier would include locks in the Rigolets and Chef Menteur Pass, as well as a lock in the Inner Harbor Navigation Canal at its confluence with Lake Pontchartrain (in the Seabrook area). The locks would limit hurricane storm surges from entering into Lake Pontchartrain and reduce high-salinity flows into the lake from the Gulf of Mexico via the Mississippi River-Gulf Outlet (MRGO), which was under construction at the time. As part of this original “Barrier Plan,” the existing levees along all three outfall canals were deemed adequate for hurricane protection purposes.
