Houston Ship Channel - Bridge Construction --- To: June 2027 --- The Harris County Toll Road Authority (HCTRA) and a contractor are conducting over-the-water construction of the new Beltway 8 (Sam Houston Tollway Ship Channel Bridge) over the Houston Ship Channel. Overhead construction on areas outside the navigable channel are in progress. The U.S. Coast Guard Captain of the Port Houston-Galveston has established Safety Zones for the waters outside the federal channel surrounding the existing pillars. Vessels transiting this area are directed to utilize the marked federal channel and should remain clear of transiting beneath the overhead work. Channel closures to support work over the federal channel are expected to commence near the end of December 2026. Overnight closures, likely in the 8 to 10 hour range, every other night for a week will be needed. Following a round of overnight closures, the U.S. Coast Guard VTS will schedule 2-3 hour blocks of no traffic in daylight hours to allow for deck placement. A pattern of these closures are expected to continue for 4-5 months. Additional planning meetings focused on minimizing disruptions will be held with Port Partners as the closure dates approach. Mariners are urged to transit this area with extreme caution and check updated notices regarding closures prior to transiting the area.

Mobile River Channel - Safety Zone --- To: May 2030 --- The Captain of the Port (COTP) Mobile is enforcing a fixed Safety Zone in accordance with 33 CFR 165.T08-1214 surrounding the M/V EX ENTERPRISE as the vessel is moored at a receiving facility located on the Mobile River at 701 South Royal Street, Mobile, AL. This Safety Zone is necessary to protect personnel, vessels, and the marine environment from hazards associated with a dismantling operation, including removal of hazardous and regulated materials, and continuous work activity on and around the hull. All navigable waters of the Mobile River along the RDB will be designated as a fixed moored Safety Zone and will be bound by the following coordinates: 30-40.57N 088-02.27W, 30-40.57N 088-02.22W, 30-40.30N 088-02.08W, 30-40.32N 088-02.27W and north along the shoreline to the point of origin. The Safety Zone does not include waters within the Mobile River Federal Channel; therefore, no impact to commercial vessel traffic is anticipated. This zone will be enforced for the duration of dismantling operations, and remain in effect until the COTP determines the area no longer presents safety concerns. The dismantlement project is expected to progress to a safe stage approximately May 2030. In the event this fixed moored Safety Zone is no longer needed before May 2030, mariners will be notified through a Marine Safety Information Bulletin (MSIB) or other appropriate means. No person may enter or remain in the zone unless authorized by the COTP or a designated representative. Those in the Safety Zone must comply with all lawful orders or directions given to them by the COTP or the COTP’s designated representative. To seek permission to enter, mariners can contact the COTP or the COTP’s representative on VHF-FM Channel 16.

--- MSIB 19-26: Calcasieu Lock GIWW Navigational Considerations --- Due to a collision with the Black Bayou Bridge causing significant structural damage, and several documented near-miss situations at the Grand Lake Bridge investigated by MSU Lake Charles, this Marine Safety Information Bulletin (MSIB) brings heightened awareness to all commercial vessels with anticipated voyages in the GIWW east of the Calcasieu Locks, specifically between Miles 229.0 and 239.0, WHL. Mariners are advised that this waterway features a narrow channel, two swing bridges, and the Calcasieu Lock, which is currently undergoing maintenance and is closed to marine traffic from 7:00 a.m. to 7:00 p.m., Monday through Friday, through September 2026. These characteristics may present navigational challenges for transiting vessels and tows. Furthermore, mariners are advised that contact with the fendering systems of the Grand Lake Bridge should be avoided at all costs. Damage to these fenders could result in enforcement action by U.S. Coast Guard MSU Lake Charles. For all commercial vessels transiting this area, consideration should be given to voyage planning, navigational assessments, posting suitable lookouts, and maintaining a safe speed to allow for timely and effective maneuvers. These considerations are not exhaustive and do not supersede navigation rules, sound mariner judgment, or good seamanship. Compliance with a vessel’s Towing Safety Management System (TSMS), where applicable, remains essential. All commercial vessel operators are strongly encouraged to share this MSIB with their vessel crews during voyage planning for transits through this area. For questions about this MSIB, mariners can contact the U.S. Coast Guard MSU Lake Charles Waterways Department at: [email protected].

Mississippi River, Mile 120.3 to 120.5 – Riverbank Degradation --- Reported: 2026-07-02 --- Mariners shall avoid pushing vessels into the riverbank along the RDB of the Mississippi River, between Mile 120.3 and 120.5, AHOP. Repeated barge contact against the riverbank has severely compromised this reach, which is now degraded and encroaching on the Mississippi River Levee System. Mariners and fleet operators are not to push into the riverbank and must proceed at their slowest rate of speed in this area in order to minimize wake and subsequent damage to flood protection systems. Mariners should secure their vessels and barges in a manner that ensures there will be no contact with the levees or revetments and that barges are no closer than 180 ft from the centerline of the levee. Vessel owners or other persons responsible for any vessel or barges making contact with the levees or revetments in any way may be charged as provided for in the River and Harbor Act, and its amendments, as codified in 33 CFR 401, 408 and 412.

Marine Safety Alert 02-24 - Inspections and Compliance Directorate --- DANGEROUS BYCATCH FROM DISCARDED MUNITIONS REMAINS A PRESENT DAY HAZARD --- This Safety Alert is being issued to raise awareness of lurking hazards caused by discarded munitions, which often contain active explosives or chemical agents. Although the practice of dumping munitions into the sea ceased in 1970, a significant amount remains hidden in coastal waters, posing a safety hazard to commercial fisherman, dredge operators, and others who trawl and work the ocean floor. Recently, a deckhand on a clamming vessel was severely burned when a canister was dredged up and brought onboard with clams and other debris. The canister likely contained mustard gas or another blistering agent, but did not display any obvious visual, audible, or odor indicators of discharging content. A member of the crew discovered the canister and threw it back overboard. Several hours later he developed a severe rash that required professional medical treatment. Mustard gas is a chemical weapon developed during World War I. Millions of pounds of this product, other chemical weapons, bombs, torpedoes, artillery shells, and munitions were routinely disposed of and remain in U.S. coastal waters. Although many munition dump areas are well marked on navigation charts, numerous areas where munitions were discarded remain unmarked. There is also evidence suggesting that munitions were frequently “short dumped,” meaning dumped outside of the designated areas by contractors hired to take them to the intended locations. The Coast Guard previously issued Safety Alert 11-16 and Safety Alert 6-10 on this same topic and continues to strongly recommend that persons involved in the fishing and dredging industries: Review their navigational charts to ensure the areas in which they are trawling or dredging are not near labeled “Explosives Dumping Areas.” Such areas must be given wide berth and seafarers should recognize that surface bottoms change and that objects can move significant distances from their original disposal areas. Review and follow recommendations from the Maritime Industry 3Rs Explosive Safety Guide. Carefully record the position of any munitions encountered and returned to the sea. Immediately report discovery to the National Response Center, at (800) 424-8802 to ensure a proper response and potential recovery. Alternatively, the local U.S. Coast Guard unit may be notified via VHF-FM Channel 16. This Safety Alert is provided for informational purposes only and does not relieve any domestic or international safety, operational, or material requirement.

Alabama River - In accordance with Section 7-11 of the ACT Master Water Control Manual dated April 2022, full navigation channel availability on the Alabama River is dependent upon channel maintenance, seasonal flow conditions, and basin status. Flows for navigation are most needed in the unregulated portion of the lower Alabama River below Claiborne Lock and Dam. Alabama Power Company (APC) operates its reservoirs on the Coosa and Tallapoosa Rivers to provide a minimum navigation flow target in the Alabama River at Montgomery, Alabama. Basin status criteria are correlated to APC Drought Operations (ADROP) updates which monitors drought triggers related to basin inflow, state line flow on the Coosa River between Georgia and Alabama, as well as composite storage availability within the APC projects. These updates are provided monthly on the first and third Tuesday. Below is the most recent ADROP update provided by Alabama Power Company on October 20, 2026: *ADROP UPDATE* - Low Basin Inflow: FALSE - - Low State Line Flow: FALSE - - Low Composite Storage: FALSE - - Montgomery Flow Target: 4,200 cfs daily average (NOTE: ADROP requires one drought intensity level change per cycle regardless of the number of triggers enacted when exiting drought operations.) - - Current Operations: Drought Intensity Level 1 - Currently, based on profile survey conducted on 04JUN2024, a 10 ft tailwater elevation near Claiborne Lock is required to provide a 9 ft navigation channel on the lower Alabama River. A modified depth of 7.5 ft navigable draft can be provided with a tailwater elevation of 8.5 ft at the Claiborne Lock and Dam. Commercial mariners should check water levels daily and schedule lockage appointments by calling the Claiborne Lock Supervisor at (251) 282-4575. Tailwater elevations below Claiborne Lock and Dam can be viewed at: https://waterdata.usgs.gov/monitoring-location/USGS-02428401
