The Corps of Engineers Mississippi Valley New Orleans (MVN) continues to address the shoaling on the Crossings Above New Orleans and in the New Orleans Harbor. The MVN is working to restore full channel dimensions on the Crossings with the three dustpan dredges. Federally authorized channel dimensions on the Crossings Above New Orleans are 45 feet by 500 feet.
SOUTHWEST PASS STONE FORESHORE DIKE and STONE JETTY REPAIRS:
The MVN received supplemental funding that enabled a contract to be awarded to EFT Diversified, Inc. to conduct critical repairs to the foreshore rock and jetties in SWP ranging from the Head of Passes (Mile 0) to Mile 20.2 BHP. The equipment including the first stone barges arrived last week and the work began at Mile 4.2 BHP on the right descending bank (west side) on Saturday, September 22, 2018. The stone operations are presently working upriver towards the Head of Passes.
The contract is expected to take approximately one year to complete. All work and equipment are expected to remain inside the wing dams (lateral pile dikes), therefore, no transit restrictions are expected.
The equipment expected to be utilized includes the following: M/V CROSBY RAMBLER, M/V JULIE MARIE, SPUD BARGE AB 8 with 88B Dragline, SPUD BARGE AB7 with 800 Linkbelt Excavator and a 24-foot aluminum crewboat.
The graph below is reproduced from NOAA’s National Weather Service website and represents an experimental product to account for the complexity of accurately predicting long-range precipitation. This forecast projects stage levels based on expected precipitation for 2 days (top) and 16 days (bottom) and was developed within the North American Ensemble Forecast System (NAEFS) computer model and highlights Quantitative Precipitation Forecasts (QPF). Along with the forecasts, a shaded area is also provided to indicate uncertainty for the forecast each day in the future. These plots are experimental and not an official forecast product.
