The project, managed by Donjon Marine Co., LLC, is designed to maintain safe and efficient passage for commercial and maritime traffic in this busy waterway. Work is scheduled to begin on July 27, 2026, and conclude by September 14, 2026, with operations running seven days a week for twelve hours each day. The project site is located at latitude 40° 38' 44.2428\" N and longitude 74° 10' 46.2036\" W.\nOn-site equipment will include a dredge, a tending tug, hopper scows, a towing tug for loaded scows, and a crew boat. For safety and coordination, vessels involved in the project will operate on radio channel 78 and monitor channels 13 and 14. To minimize impacts on navigation, the project will follow a “move on demand” approach, with a tending tug available to relocate the dredge and scows as needed to avoid impeding other vessels. Mariners are encouraged to coordinate passing arrangements with the project team to ensure safe and efficient transit through the area.\nFor ongoing updates and guidance, the Local Notice to Mariners (LNM) will provide official information to the maritime community. Questions or concerns can be directed to Brian P. Henry at Donjon Marine Co., LLC via email at brian.henry@donjon.com or by phone at 908-413-3003.\n","COORDINATES_JSON":"{\"type\":\"Point\",\"coordinates\":[-74.1795,40.64567]}","COORDINATES_TYPE":"Point","DECIMAL_LONGITUDE":-74.1795,"DECIMAL_LATITUDE":40.645669999999996}},{"type":"Feature","id":49315,"geometry":{"type":"Point","coordinates":[-124.43354,42.41883000000007]},"properties":{"ESRI_OID":49315,"MSI_UID":49315,"ATU":13,"TITLE":"Sector Columbia River, Submerged Land Act (SLA) - Rogue River/General/Marine Construction (Excluding Bridges)/Dredging","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Marine Construction (Excluding Bridges)","TYPE":"Dredging","WTRW_UID":100116385762,"MRN":"urn:mrn:iala:wwy:us:navXII:dis13:seccolrivexcecozon:seccolrivtersea:seccolrivsublanact:rogriv","WATERWAY_NAME":"Rogue River","CREATE_DATE":1784664335000,"MODIFIED_DATE":1784664343000,"BEGIN_DATE":1784592000000,"END_DATE":1785369599000,"DESCRIPTION":"The M/V YAQUINA may be conducting dredging activities at the Rogue River Entrance (RM 00-25 to RM 00+10) from 21 - 28July 2026.
