Rota Harbor (West Harbor) is located on the island of Rota, in the Commonwealth of Northern Mariana Islands. The project was authorized under Section 107 of the River and Harbor Act of 1960. The local sponsor is the CNMI Government, Commonwealth Ports Authority. The project is in the operations and maintenance phase.
The project was completed in 1985 at a cost of $2.7 million. The Harbor consists of an entrance channel (685 feet long, 300 feet wide, 20 feet deep); a turning basin (440 feet long, 150-450 feet wide, 16.5 feet deep); a revetted mole (535 feet long, 10 feet high); a basin extension (280 feet long, 150 feet wide and 16.5 feet deep); and appurtenant aids to navigation.
Rota has two harbors, which comprise the only harbor facilities serving the island. The West Harbor is the most modern port facility in the Commonwealth and is primarily used for the import of commercial goods.
The U.S. Army Corps of Engineers is responsible for maintaining the project structures and project depths in the entrance channel and basin areas. Maintenance dredging was conducted in 2008.
