The dam sits about 20 miles upstream from Covington, Va., on the Jackson River in Alleghany County, Va. The dam is a rolled rock fill embankment with a compacted earthen clay core, outlet works and an emergency spillway located at the right abutment. The embankment is 1,310 feet long with a height of 257 feet. The width is 32 feet at the top of the dam with a maximum width of 1000 feet at its base.

SAVANNAH, Ga. -- Archeologists working for the U.S. Army Corps of Engineers, Savannah District, aided by divers and salvage operations teams from the U.S. Navy, retrieve a 64-square foot section of a Civil War ironclad warship from the bottom of the Savannah River the evening of Nov. 12, 2013. U.S. Navy photo.

The divers worked in strong currents with near-zero visibility to assess the possibility of lifting a small piece of the Confederate ship’s casemate for archeological testing. A crane lifted it onto a barge anchored near historic Old Fort Jackson on the eastern edge of Savannah. Experts estimate the piece weighs more than 5,000 pounds.

The Confederate navy scuttled the CSS Georgia in 1864 as Union troops approached Savannah. The iron-covered ship remained on the river bottom until 1969 when a dredge removing sediment from the shipping channel struck a portion of the ship, according to Julie Morgan, staff archeologist for the Corps’ Savannah District. A brief recovery effort in the late 1980’s removed two cannon, various types of munitions and other artifacts.

“This retrieval will play a major role in creating a research design to effectively remove the CSS Georgia before expanding the shipping channel along this stretch of the Savannah River,” said Morgan. “It took a dedicated team working in some very tough conditions to bring this piece to the surface.”

Over time the ship’s casemate, the iron-covered upper portion of the warship, came apart. The small portion removed Nov. 12 will give archeologists the ability to assess the condition of the remainder of the ship, according to Morgan, and ensure the team follows protocols from the National Historic Preservation Act of 1966.

The Savannah Harbor Expansion Project (SHEP) includes removal and preservation of CSS Georgia, which sits immediately adjacent to the shipping channel. The SHEP will deepen Savannah’s harbor from its current 42-foot depth to 47 feet, greatly expanding its capability to handle larger cargo vessels.

The labor-intensive job of diverting fresh water into the Savannah National Wildlife Refuge has become easier since the U.S. Army Corps of Engineers Savannah District replaced the old wooden structures with custom-built diversion gates. The Fresh Water Control System was originally installed as a mitigation feature for the 1977 Savannah harbor deepening project. At a cost of $12.5 million, the new stainless steel structures modernize and automate the process of controlling water in the area. Previously, wildlife managers with the U.S. Fish and Wildlife Service could only route water to 3,000 acres of wetlands for waterfowl; with the gate improvements, the water management area has doubled to 6,000 acres. The project was completed in autumn 2011.

Ray Schembri (in blue), a longtime hydraulic engineer with the U.S. Army Corps of Engineers, New York District, shows USACE personnel the Pompton Lake Dam floodgates in the Passaic River Basin Wednesday September 19, 2012. The floodgates were designed and constructed by the Corps of Engineers and following their completion the gates were turned over to the state of New Jersey, which now owns, maintains and operates them.

Schembri took a group of USACE personnel working on the Passaic River Basin General Re-evaluation Study (including mostly engineers, but also biologists, real estate specialists and more) around the Passaic River Basin to see in person some of the major hydraulic points of interest so they could get a better understanding of the basin. The study is a partnership between the U.S. Army Corps of Engineers and the state of New Jersey to evaluate and compare potential flood risk management alternatives for the Passaic River Basin.

Beyond the boat is a vane dike built to modify the current which, when the gates of McAlpine Dam are open to let water pass, runs from near the Kentucky bank toward the open gates. This current (called outdraft because it flows out away from the bank) tends to push downbound tows toward the dam instead of into the canal where they want to go. As I (no expert) understand it, the vane dike deflects some of this outdraft so it flows more toward the entrance to the canal. The diverted water then flows through a gap (partly seen at left) between the downriver end of the dike and the upriver end of Shippingport Island. The top of the dike is only a few feet higher than pool stage, so when the river rises significantly, the dike is submerged and has little or no effect. At the time of this photo, the upper gates were barely open, and while I don't know about the lower gates, I think the outdraft would have been minimal.

The dam is a rolled rock fill embankment with a compacted earthen clay core, outlet works and an emergency spillway located at the right abutment. The embankment is 1,310 feet long with a height of 257 feet. The width is 32 feet at the top of the dam with a maximum width of 1000 feet at its base.

The gate house and dam spillway at Mansfield Hollow Dam, Mansfield, Conn. Mansfield Hollow Dam lies on the confluence of the Natchaug, Fenton and Mt. Hope Rivers, in Mansfield, Conn. The dam is part of a network of six flood control dams in the Thames River Basin constructed and maintained by the U.S. Army Corps of Engineers. This network helps to reduce flooding in communities within the Thames River Basin by regulating water levels on upstream tributaries in Connecticut and Massachusetts.

The labor-intensive job of diverting fresh water into the Savannah National Wildlife Refuge has become easier since the U.S. Army Corps of Engineers Savannah District replaced the old wooden structures with custom-built diversion gates. The Fresh Water Control System was originally installed as a mitigation feature for the 1977 Savannah harbor deepening project. At a cost of $12.5 million, the new stainless steel structures modernize and automate the process of controlling water in the area. Previously, wildlife managers with the U.S. Fish and Wildlife Service could only route water to 3,000 acres of wetlands for waterfowl; with the gate improvements, the water management area has doubled to 6,000 acres. The project was completed in autumn 2011.

John Bianco (in red) a longtime engineer with the U.S. Army Corps of Engineers, North Atlantic Division Office, discusses flooding issues with USACE personnel at Beatties Dam in Little Falls, N.J., while traveling around the Passaic River Basin Wednesday September 19, 2012. Ray Schembri (in blue), a longtime hydraulic engineer with the U.S. Army Corps of Engineers, New York District, took a group of USACE personnel working on the Passaic River Basin General Re-evaluation Study (including mostly engineers, but also biologists, real estate specialists and more) around the Passaic River Basin to see in person some of the major hydraulic points of interest so they could get a better understanding of the basin. The study is a partnership between the U.S. Army Corps of Engineers and the state of New Jersey to evaluate and compare potential flood risk management alternatives for the Passaic River Basin.

One of the six alternatives being evaluated as part of the study includes looking at possible modifications to Beatties Dam. (photo by Chris Gardner, New York District public affairs)
