The U.S. Army Corps of Engineers (USACE) Philadelphia District has issued an important update regarding dredging operations at New Jersey’s Manasquan Inlet. This update follows the discovery of rapid shoaling near the south jetty, which has affected navigation for mariners.
USACE Conducts Hydrographic Surveys to Address Shoaling
Hydrographic Surveys Completed on August 6, 2024
On August 6, 2024, USACE completed detailed hydrographic surveys to assess the extent of the shoaling in Manasquan Inlet. These surveys were promptly shared with the U.S. Coast Guard and are available online for mariners via the USACE website.
Rapid Shoaling Threatens Navigation
Shoaling has become a persistent issue inside the south jetty, affecting safe navigation through the inlet. Mariners navigating this area are advised to stay informed and consult the updated survey data before planning their routes.
Dredge MURDEN Begins Essential Dredging Operations
Dredge MURDEN Completes Initial Dredging Cycles
To address the shoaling, the USACE Dredge MURDEN completed two cycles of dredging on August 6, 2024. Weather permitting, the MURDEN is scheduled to resume dredging operations around August 10, 2024. The entire dredging process is expected to take between one and two weeks, depending on sea conditions.
Collaboration Across USACE Districts Enables Faster Action
USACE Philadelphia District Commander Lt. Col. Jeffrey Beeman praised the collaborative efforts across multiple districts. “I’m grateful to the USACE Wilmington, New England, and New York Districts for their flexibility in rearranging operations, allowing us to move forward this weekend rather than later in the month,” Beeman stated. “I also want to acknowledge the hard work of our survey crews and the MURDEN team.”
Manasquan Inlet Conditions and Safety Advisory for Mariners
Dynamic Nature of Manasquan Inlet
Manasquan Inlet is known for its rapidly changing conditions. Significant shoaling often occurs, influenced by wind and wave conditions, which can dissipate shoaling but also create unpredictable hazards for mariners.
Mariners Urged to Exercise Caution
The U.S. Coast Guard has issued warnings to mariners navigating through the inlet. Given the constantly shifting conditions, mariners should proceed with caution and regularly check for updates on navigation advisories.
Public Safety Warning: Avoid the Unstable Shoal
Public Urged to Avoid Shoal Areas After Dredging
USACE also issued a public safety warning, advising people to avoid walking or recreating on the shoal. Due to the inlet’s dynamic nature, the shoal remains unstable, especially following dredging operations. It poses a significant risk of collapse.
