48 United States Army Corps of Engineers

The United States Army Corps of Engineers (USACE) is an engineer formation of the United States Army that has three primary mission areas: engineer regiment, military construction, and civil works. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the commanding general/chief of engineers. The chief of engineers commands the engineer regiment, composed of combat engineer army units, and answers directly to the chief of staff of the army. Combat engineers come from throughout the service and can be active duty, national guard, or army reserve. Combat engineers duties are to construct fighting positions, fixed/floating bridges, and obstacles and defensive positions, place and detonate explosives (sappers), conduct operations that include route clearance of obstacles and rivers, prepare and install firing systems for demolition and explosives, and detect mines. For the military construction mission the commanding general is directed and supervised by the assistant secretary of the army for installations, environment, and energy, whom the President appoints and the Senate confirms. Military construction relates to construction on military bases and worldwide installations.

249th Engineer Battalion (United States)

The 249th Engineer Battalion is a versatile power generation battalion assigned to the U.S. Army Corps of Engineers that provides commercial-level power to military units and federal relief organizations during full-spectrum operations. Additionally, the commander serves as the Commandant of the U.S. Army Prime Power School, the institution responsible for the development of Army and Navy power generation specialists.

The 1269th Engineer Combat Battalion was an engineer combat battalion that served in the United States Army in the European Theater of Operations during World War II. It saw action in France and Germany, serving notably with the Army's T-Force intelligence assault force in the capture of German atomic weapons facilities and personnel as part of Operation Big.

Army engineer divers are members of national armies who are trained to undertake reconnaissance, demolition, and salvage tasks underwater. These divers have similar skills and qualifications as professional divers. In the United States Army, they are members of the Corps of Engineers.

The Army Map Service (AMS) was the military cartographic agency of the United States Department of Defense from 1941 to 1968, subordinated to the United States Army Corps of Engineers. On September 1, 1968, the AMS was redesignated the U.S. Army Topographic Command (USATC) and continued as an independent organization until January 1, 1972, when it was merged into the new Defense Mapping Agency (DMA) and redesignated as the DMA Topographic Center (DMATC). On October 1, 1996, DMA was folded into the National Imagery and Mapping Agency (NIMA), which was redesignated as the National Geospatial-Intelligence Agency (NGA) on 2003.

The Birds Point-New Madrid Floodway is a flood control component of the Mississippi River and Tributaries Project located on the west bank of the Mississippi River in southeast Missouri just below the confluence of the Ohio and Mississippi Rivers. The construction of the floodway was authorized by the Flood Control Act of 1928 and later modified by the Flood Control Act of 1965. Its purpose is to divert water from the Mississippi River during major flood events and lower the flood stages upstream, notably at Cairo, Illinois.

The Bonnet Carré Spillway is a flood control operation in the Lower Mississippi Valley. Located in St. Charles Parish, Louisiana – about 12 miles (19 km) west of New Orleans – it allows floodwaters from the Mississippi River to flow into Lake Pontchartrain and thence into the Gulf of Mexico. The construction of the spillway was completed in 1931.

The Cape Cod Canal is an artificial waterway in the U.S. state of Massachusetts connecting Cape Cod Bay in the north to Buzzards Bay in the south, and is part of the Atlantic Intracoastal Waterway. The approximately seven-mile-long (11 km) canal traverses the narrow neck of land joining Cape Cod to the state's mainland. Most of its length follows tidal rivers widened to 480 feet (150 m) and deepened to 32 feet (9.8 m) at mean low water, shaving 135 miles (217 km) off the journey around the Cape for its approximately 14,000 annual users.

The Chicago Sanitary and Ship Canal, historically known as the Chicago Drainage Canal, is a 28-mile-long (45 km) canal system that connects the Chicago River to the Des Plaines River. It reverses the direction of the Main Stem and the South Branch of the Chicago River, which now flows out of Lake Michigan rather than into it. The related Calumet-Saganashkee Channel does the same for the Calumet River a short distance to the south, joining the Chicago canal about halfway along its route to the Des Plaines. The two provide the only navigation for ships between the Great Lakes Waterway and the Mississippi River system.

Corps Castle is the logo of the U.S. Army Corps of Engineers (USACE). The logo is typically a white castle with three towers set on a red background. When the Corps Castle is worn as insignia on a uniform, it is similar to the logo design but with a dull or shiny brass finish. The look of the Corps Castle traces its history back to the American Revolution and has evolved over time. The logo has received changes throughout the years but gets its finalizing shape from the United States Military Academy Barracks named Pershing Barracks.

The spillway stands between the Mississippi and the Morganza Floodway, which leads to the Atchafalaya Basin and the Atchafalaya River in south-central Louisiana. Its purpose is to divert water from the Mississippi River during major flood events by flooding the Atchafalaya Basin, including the Atchafalaya River and the Atchafalaya Swamp. The spillway and adjacent levees also help prevent the Mississippi from changing its present course through the major port cities of Baton Rouge and New Orleans to a new course down the Atchafalaya River to the Gulf of Mexico. The Morganza Spillway, operated by the U.S. Army Corps of Engineers, was opened during the 1973 and 2011 Mississippi River floods.

The boat has been restored and drydocked, and now houses exhibits about the Missouri River and local tourism information. The museum is a facility of the Sioux City Public Museum.

Shpack Landfill is a hazardous waste site in Norton, Massachusetts. After assessment by the United States Environmental Protection Agency (EPA) it was added to the National Priorities List in October 1986 for long-term remedial action. The site cleanup is directed by the federal Superfund program. The Superfund site covers 9.4 acres, mostly within Norton, with 3.4 acres in the adjoining city of Attleboro. The Norton site was operated as a landfill dump accepting domestic and industrial wastes, including low-level radioactive waste, between 1946 and 1965. The source of most of the radioactive waste, consisting of uranium and radium, was Metals and Controls Inc. which made enriched uranium fuel elements for the U.S. Navy under contract with the U.S. Atomic Energy Commission. Metals and Controls merged with Texas Instruments in 1959. The Shpack landfill operation was shut down by a court order in 1965.

The Soo Locks are a set of parallel locks, operated and maintained by the United States Army Corps of Engineers, Detroit District, which enable ships to travel between Lake Superior and the lower Great Lakes. They are located on the St. Marys River between Lake Superior and Lake Huron, between the Upper Peninsula of the US state of Michigan and the Canadian province of Ontario. They bypass the rapids of the river, where the water falls 21 feet (6.4 m). The locks pass an average of 10,000 ships per year, despite being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. The winter closure period is used to inspect and maintain the locks.
