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.

FOLSOM, Calif. (April 28, 2011) – Excavation work for the control structure of the auxiliary spillway – part of the third phase of the Folsom Dam Joint Federal Project (JFP) – continued here April 27. Ongoing work for the JFP at Folsom Dam will require daily explosive blasting until October of this year, said David Neff of the U.S. Army Corps of Engineers Sacramento District’s engineering division. For the public’s safety, the Folsom Lake Crossing roadway and bridge are closed Monday through Friday from 1:30 p.m. to 2:30 p.m. during blasting.

U.S. Army Corps of Engineers Los Angeles District leadership accepted the invitation of Navajo Nation Council Delegate Walter Phelps to participate in a round-table discussion at the Leupp Chapter House Dec. 6.

Col. Kirk Gibbs, district commander, David Van Dorpe, deputy district engineer, Ed Demesa, chief of the planning division, and Quana Higgins, district tribal liaison, joined the partnering engagement with Navajo Nation’s Resources and Development Committee.

"The signing of the District's first Tribal Partnership Program agreement is an important milestone, and one that we were proud to achieve with Navajo Nation," said Gibbs. "It is critical that we continue to communicate and strengthen our partnership so that we can move forward with the Watershed Study and help Navajo Nation with their water resource challenges."

Navajo Nation Vice President Jonathan Nez spoke about his vision and administrative priorities saying, "The Navajo Nation is committed to a continued partnership with the Corps through the upcoming watershed study."

Principal hydrologist for Navajo Water Resources Jason John stated, the Nation usually pursue grant opportunities but hasn't partnered in the sense that they share in the cost of the studies as under Tribal Partnership Program with USACE.

"The removal of the Sovereignty Immunity Waiver clause in our Federal Cost Share Agreements enabled them to sign the agreement with us," said Higgins.

Under the TPP, the Corps, in cooperation with tribes and other federal agencies, can complete watershed assessments or determine the feasibility of projects that will substantially benefit Indian tribes.

Next on tap is a scoping charrette, an intensive workshop, to be held by the end of January 2018. This effort will develop the Project Management Plan and define any necessary amendments to the Watershed Assessment Cost Share Agreement.

Each of the three locks at McAlpine Locks has a visible yellow stripe along the top of its far wall.

Nearest to the camera is the 600-foot lock (completed in 1921); one of its open lower gates can be seen at left.

Next is the decommissioned 360-foot lock (completed in 1872, though modified since then); its closed upper gates can be seen at right, beyond the metal-roofed building, and at far right, just below the red fire hose box, is the permanent bulkhead installed when the lock was closed for good in 1970.

Farthest from the camera is the 1200-foot main lock (completed in 1961); the first towboat to lock through was the "Philip Sporn" (doc. # 274333).
