Agat Small Boat Harbor (SBH) is located on the west coast of Guam near Gaan Point. The project was authorized for construction in June 1986 under Section 107 of the River and Harbor Act of 1960, as amended. The harbor is owned and operated by the Port Authority of Guam (PAG). The project is in the operations and maintenance phase.
The harbor was completed in March 1989 at a total cost of $2,821,800 (Corps: $1,711,500; Coast Guard: $2,000; non-Federal: $1,108,300). The project consists of an entrance channel (1000 feet long, 120 feet wide, 14 feet deep); a turning basin (200 feet long, 150 feet wide, 7 to 11 feet deep); a main access channel (500 feet long, 75 feet wide, 9 feet deep); two breakwaters (985 feet long and 65 feet long); and two revetted moles (200 feet long and 348 feet long). According to the PAG website, there are 150 slips spread out among the four recreational marinas operated by PAG.
The Agat SBH has a privately operated restaurant located on the Port owned property. The harbor houses some residential, recreational, and commercial vessels.
The U.S. Army Corps of Engineers is responsible for maintaining the project structures and project depths in the channels and turning basin area. Maintenance dredging is currently planned for 2023.
