Flooding Concerns on the Lower Pearl River Near Walkiah Bluff
Flood Assessment and Management Flooding Concerns on the Lower Pearl River Near Walkiah Bluff Amanda L. Roberts, National Weather Service Walkiah Bluff is located in south Mississippi on the East Pearl River near Wilson Slough and the divergence of the Pearl River into the East and West Pearl Rivers. Approximately 175 residents own homes on or near the East Pearl River near Walkiah Bluff, MS. Flooding often occurs in the Walkiah Bluff area whenever flooding occurs upstream on the Pearl River, thus heightening concerns of local citizens. The Lower Mississippi River Forecast Center (LMRFC) has flood forecasting responsibility in this area, however, Walkiah Bluff is not currently an official forecast point. Historical data from the period of record was utilized to develop flood forecasting guidance tools for the Walkiah Bluff area. Flood events were analyzed to obtain a better understanding of how Walkiah Bluff reacts in relationship to upstream flooding on the Pearl River at Bogalusa, LA and the Bogue Chitto River at Bush, LA. As- sessments were also made regarding how the Pearl River at Pearl River, LA reacts in association with upstream flooding at Walkiah Bluff and Bush. The effects of the Bogue Chitto River on the crest at Walkiah Bluff, MS are complicated due to numerous sloughs and bayous that interconnect the two channels. It is difficult to accurately interpolate any affects from the Bogue Chitto by utilizing a crest to crest curve for Bogalusa to Walkiah Bluff. However, because the crest at Pearl River, LA is based upon water routed from both Bogalusa and Bush, the LMRFC forecast for Pearl River, LA can be utilized along with the crest to crest curve for Walkiah Bluff to Pearl River, LA to essentially back-forecast the crest at Walkiah Bluff. -
COMMON BOTTLENOSE DOLPHIN (Tursiops Truncatus Truncatus) Mississippi Sound, Lake Borgne, Bay Boudreau Stock
May 2015 COMMON BOTTLENOSE DOLPHIN (Tursiops truncatus truncatus) Mississippi Sound, Lake Borgne, Bay Boudreau Stock NOTE – NMFS is in the process of writing individual stock assessment reports for each of the 31 bay, sound and estuary stocks of common bottlenose dolphins in the Gulf of Mexico. Until this effort is completed and 31 individual reports are available, some of the basic information presented in this report will also be included in the report: “Northern Gulf of Mexico Bay, Sound and Estuary Stocks”. STOCK DEFINITION AND GEOGRAPHIC RANGE Common bottlenose dolphins are distributed throughout the bays, sounds and estuaries of the northern Gulf of Mexico (Mullin 1988). Long-term (year-round, multi-year) residency by at least some individuals has been reported from nearly every site where photographic identification (photo-ID) or tagging studies have been conducted in the Gulf of Mexico (e.g., Irvine and Wells 1972; Shane 1977; Gruber 1981; Irvine et al. 1981; Wells 1986; Wells et al. 1987; Scott et al. 1990; Shane 1990; Wells 1991; Bräger 1993; Bräger et al. 1994; Fertl 1994; Wells et al. 1996a,b; Wells et al. 1997; Weller 1998; Maze and Wrsig 1999; Lynn and Wrsig 2002; Wells 2003; Hubard et al. 2004; Irwin and Wrsig 2004; Shane 2004; Balmer et al. 2008; Urian et al. 2009; Bassos-Hull et al. 2013). In many cases, residents predominantly use the bay, sound or estuary waters, with limited movements through passes to the Gulf of Mexico (Shane 1977; Shane 1990; Gruber 1981; Irvine et al. 1981; Shane 1990; Maze and Würsig 1999; Lynn and Würsig 2002; Fazioli et al. -
Supplemental Environmental Assessment #269-A: Mississippi River Gulf Outlet, South of Lake Borgne, Additional Disposal Areas
PO-32 Ph2 request item #4f ENVIRONMENTAL ASSESSMENT LAKE BORGNE - MRGO SHORELINE PROTECTION PROJECT ST BERNARD PARISH, LOUISIANA EA #402 INTRODUCTION The U.S. Army Corps of Engineers (USACE), New Orleans District (CEMVN) prepared Environmental Assessment #402 (EA #402) to evaluate the potential impacts associated with the proposed Lake Borgne – Mississippi River Gulf Outlet (MRGO) Shoreline Protection Project. EA #402 was prepared in accordance with the National Environmental Policy Act of 1969 and the Council on Environmental Quality’s Regulations (40 CFR 1500-1508), as reflected in the USACE Engineering Regulation, ER 200-2-2. PURPOSE AND NEED FOR THE PROPOSED ACTION The purpose of the proposed action is to protect salt marsh from erosion, between Lake Borgne and the MRGO in the vicinity of Shell Beach and Hopedale. This project is a Coastal Wetland Planning, Protection and Restoration Act (CWPPRA) project and was selected for completion by the Louisiana Coastal Wetlands Conservation and Restoration Task Force. The action is needed because high-energy waves are eroding wetland habitat along the south shore of Lake Borgne and the north bank of the MRGO. Continued erosion along both shorelines could eventually result in the merging of Lake Borgne and the MRGO. AUTHORITY FOR THE PROPOSED ACTION The Coastal Wetlands Planning, Protection and Restoration Act (Public Law 101-646) authorized the proposed action and the local cost share is being provided from the State of Louisiana’s Wetlands Conservation Trust Fund (LA. R.S. 49:213 et seq). PRIOR REPORTS Environmental Impact Statement: Operation and Maintenance Work on Three Navigation Projects in the Lake Borgne Vicinity, Louisiana, May 21, 1976. -
Golden Triangle Marsh Creation Council (LA RESTORE 002 000 Cat1)
Gulf Coast Mississippi River Delta Watershed Ecosystem Restoration Golden Triangle Marsh Creation Council (LA_RESTORE_002_000_Cat1) Project Name: Golden Triangle Marsh Creation - Planning Cost: Category 1: $4,347,733 Responsible Council Member: State of Louisiana Project Details: This proposed project would complete planning to create approximately 600 acres of marsh within the Golden Triangle Marsh system. Because the Inner Harbor Navigation Canal/Lake Borgne Surge Barrier stretches across the Golden Triangle Marsh, these wetlands provide an important natural buffer in the multiple lines of defense protecting geographically vulnerable communities in New Orleans from storm surge. In addition, the Golden Triangle Marsh falls within - and would enhance if fully implemented - the Bayou Sauvage National Wildlife Refuge, which includes fresh and brackish marshes and coastal hardwood forest, and serves as valuable wildlife, fish, and shellfish habitat. Activities: Activities would include engineering and design of the Golden Triangle Marsh Creation project, leading to construction-ready plans and specifications and the development of an adaptive management plan to guide decision-making for future project maintenance activities. If the plans are implemented in the future, the project would be constructed by hydraulically dredging and pumping sediment from Lake Borgne to a 600-acre fill site located approximately 16 miles from the borrow site. The borrow area, which consists mostly of clays and silts, currently has a depth of -10 feet and would be dredged to a depth of -30 feet. Earthen containment dikes would be constructed to facilitate the construction of the marsh. The engineering and design and permitting is expected to take three years to complete. -

Redundant Hydraulic and Control System at the Seabrook Gate Complex, New Orleans, LA
Redundant Hydraulic and Control System at the Seabrook Gate Complex, New Orleans, LA Robert Ferrara, President Thomas Behling, Systems Engineer Abstract The Seabrook Floodgate complex utilizes a 95-foot opening sector gate flanked by two 50-foot opening vertical lift gates that tie into T walls connecting to the existing levee system surrounding the city. The project is located at the northern end of the Inner Harbor Navigation Canal (IHNC), near Lake Pontchartrain in New Orleans, Louisiana. The project was constructed for the U.S. Army Corps of Engineers (USACE). The major objective of the project was to work in tandem with the Inner Harbor Navigation Canal Surge Barrier on the Gulf Overhead view of sector and lift gates at Intercoastal Waterway at Lake Borgne to block storm surge from Seabrook Gate Complex Lake Borgne and Lake Pontchartrain during storm events. The USACE required that the gates provide 100-year-level of protection against the 1 percent exceedance, meaning +16.0 feet level coverage for all gates. The lift gates at the Seabrook complex are driven by hydraulic systems integrated with closed loop controls for controlled motion. Six different hydraulic power units in conjunction with eight separate remote control stations and consoles and an integrated redundant control drive the gates to required storm position. Introduction The Seabrook Floodgate Complex is located at the mouth of the Inner Harbor Navigation Canal, also called the Industrial Canal, at Lake Pontchartrain. Alberici Constructors were selected to engineer, construct, install, commission and, for the 2012 hurricane season, operate the gate. The original design had only one sector gate set at the complex. -

Prioritizing Waterway Lock Projects: Barge Traffic Changes
Prioritizing Waterway Lock Projects: Barge Traffic Changes Updated June 1, 2018 Congressional Research Service https://crsreports.congress.gov R45211 Prioritizing Waterway Lock Projects: Barge Traffic Changes Summary Congress faces decisions about prioritizing new lock construction projects on the inland waterway system. As both houses debate differing versions of water resources and development bills (S. 2800, H.R. 8) and the FY2019 Energy and Water Development Appropriations bill (S. 2975, H.R. 5895), the decision about which of these projects could be undertaken first will likely be among the most controversial issues. The inland waterway system supports barge transportation of heavy raw materials such as grain, coal, petroleum, and construction aggregates. The new locks are needed, according to the Army Corps of Engineers (USACE) and barge shippers, where existing locks are in poor condition, requiring frequent closures for repairs, and/or because a lock’s size causes delays for barge tows. The total estimated cost for the 21 planned lock projects is several billion dollars (many of the individual projects have a cost estimate of between $300 million and $800 million). However, available funding for these projects is about $200 million per year. This is because of limited appropriations and cost-sharing capabilities. Under current cost-share arrangements, the barge industry pays half the cost of construction projects. It does this by paying a $0.29 per gallon fuel tax, which annually generates around $100 million. Significant changes in traffic levels through particular locks may affect the benefits that were estimated as expansion projects were advanced. The calculation of benefits is critical to advancing a project: the Office of Management and Budget (OMB) will not request funding for a project unless the estimated economic benefit is at least 2.5 times the expected cost. -
