*The reported extreme of 38.70 inches at Yankeetown on September 5, 1950 is an estimated depth of rainfall calculated as part of a post-storm survey of Hurricane Easy (Cedar Keys Hurricane). Value has historically been considered reasonably accurate (and even an underestimate of actual rain fall), but an estimate cannot be considered an official observation from a reliable precipitation gauge.

GULF INTRACOASTAL WATERWAY WEST CLOSURE COMPLEX


The Gulf Intracoastal Waterway West Closure Complex is a part of the New Orleans Drainage System; it consists of a navigable floodgate, a pumping station, flood walls, sluice gates, foreshore protection, and an earthen levee. The complex was designed to reduce the risk for residences and businesses in the project area from a storm surge associated with a tropical event, with an intensity that has a one-percent chance of occurring in any given year.

When the gate is closed during a storm event, the 19,246 cubic feet per second 11 bay pump station is required to evacuate the rainwater that is pumped into Harvey and Algiers canals by 9 other pump stations along the canals.

The pump station, which is the largest in the world, consists of 11 Caterpillar engines each producing 5,444 horsepower. The pumps could fill an Olympic-sized swimming pool in 3 seconds.


INHC-LAKE BORGNE SURGE BARRIER



The 1.8-mile-long Inner Harbor Navigation Canal (IHNC)-Lake Borgne Surge Barrier is located at the confluence of the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO), about 12 miles east of downtown New Orleans. The surge barrier works in tandem with the Seabrook Floodgate Complex at the north end of the IHNC (also known locally as the Industrial Canal) near Lake Pontchartrain. The projects reduce the risk associated with a storm surge that has a one percent chance of occurring in any given year, or a 100-year storm.

At a cost of $1.3 billion, the IHNC-Lake Borgne Surge Barrier is the largest design-build civil works project in the history of the U.S. Army Corps of Engineers.

The IHNC-Lake Borgne Surge Barrier is the largest continuous surge barrier in the world.

SEAWISE GIANT



At a length of 1,505 feet, the Seawise Giant, an ultra-large crude carrier (ULCC) supertanker, is the longest ship ever built.

Seawise Giant was ordered in 1974 and delivered in 1979 by Sumitomo Heavy Industries, Ltd. at its Oppama shipyard in Yokosuka, Kanagawa, Japan.

Seawise Giant possessed the largest deadweight tonnage ever recorded: 564,763 tons. Fully loaded, its displacement was 657,019 tons.

The heaviest ship of any kind, and with a laden draft of 81 feet, it was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. Overall, it is generally considered the largest* ship ever built.

In 2009, the vessel was sold to Indian ship breakers and beached for scrapping.

*Seawise Giant was not the largest by gross tonnage, ranking sixth at 260.941 GT, behind the crane ship Pioneering Spirit and 4 Batillus-class supertankers.
