Lower Mississippi River (LMR) Dredging Update 82318

The Corps of Engineers Mississippi Valley New Orleans (MVN) continues to respond to the shoaling, created by the extended high river stages of early 2018, on the Crossings Above New Orleans and in the New Orleans Harbor.  The MVN is working to restore full channel dimensions on the Crossings Above New Orleans with up to three dustpan dredges as the Fiscal Year winds down.  Federally authorized channel dimensions on the Crossings Above New Orleans are 45 feet by 500 feet.                                                                                                      

The Carrollton Gauge reading at 1500 hours today was 4.20 feet, with a 24-hour change of + 0.20feet.

The Baton Rouge Gauge reading at 1600 hours today was 12.56 feet, with a 24-hour change of + 0.30 feet.

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.

DUSTPAN DREDGES ON THE CROSSINGS ABOVE NEW ORLEANS:

WALLACE McGEORGE: The industry dustpan dredge WALLACE McGEORGE will commence dredging full channel dimensions (500 feet) by tomorrow morning at Baton Rouge Front lower end (approximately Mile 228 Above Head of Passes [AHP]) or just below the Baton Rouge I-10 Bridge. The WALLACE McGEORGE commenced dredging on the Crossings on Friday, May 11, 2018.

JADWIN: The Corps’ dustpan dredge JADWIN continues dredging full channel dimensions (500 feet) at Belmont Crossing (Mile 154 AHP). The NOBRA and Federal Pilots will anchor vessels in the Belmont Anchorage (Mile 154 AHP To Mile 152.9 AHP) “as far east as possible” in an effort to keep the Anchorage accessible while the dustpan dredge is working this location. The JADWIN began dredging on the Crossings on Thursday, May 10, 2018.

GOVERNMENT HOPPER DREDGE AT SOUTHWEST PASS:

WHEELER: The MVN’s hopper dredge WHEELER continues dredging under Readiness Exercise #3-2018. The WHEELER is presently dredging from Mile 4.5 Below Head of Passes (BHP) to Mile 7 BHP. Readiness Exercise #3-2018 began as scheduled on August 14th and is expected to be completed on August 29th.
