The geography of Apra Harbor has been extensively modified from its pre-historical state by humans. The entrance to the harbor is flanked by [[Point Udall (Guam)|Point Udall]], formerly Orote Point, to the south and Spanish Rocks at the tip of the Glass Breakwater. The Glass Breakwater, built on top of Calalan Bank and the fringing Luminao Reef, connects to [[Cabras Island]], the location of the [[Port of Guam]], which handles more than 90% of civilian cargo imported to Guam. Inland areas in the [[villages of Guam|villages]] of [[Piti, Guam|Piti]] and [[Santa Rita, Guam|Santa Rita]] form the eastern boundary of the harbor. There are two small artificial peninsulas jutting into the eastern end of the harbor. The northernmost is named [[Drydock Island]], the tip of which is a military reservation with wharves for fueling ships. South of Drydock Island is [[Sasa Bay]], one of five marine preserves created by the [[Government of Guam]]. The southern boundary of Sasa Bay is formed by Polaris Point, a geographically separate part of [[Naval Base Guam]] that is the homeport of [[Submarine Squadron 15]].<ref>{{cite web |title=Polaris Point |url=https://www.cnic.navy.mil/Regions/jrm/installations/navbase_guam/about/installations/polaris_point/ |website=Commander, Naval Installations Command |access-date=8 March 2021}}</ref> Polaris Point and the Orote Peninsula form the entrance to Inner Apra Harbor, a military restricted area. The Orote Peninsula holds the main part of Naval Base Guam and is approximately four miles to its tip at Point Udall. There are two named large coral formations roughly west of Sasa Bay in Outer Apra Harbor: Western Shoals and Jade Shoals.

Ten rivers flow into Apra Harbor: [[Atantano River]], [[Sasa River]], [[Aguada River]], [[Big Guatali River]], [[Aplacho River]], [[Maggo River]], [[Guatali River]], [[Laghas River]], [[Tenjo River]] and [[Paulana River]].<ref>{{cite web |title=Apra watershed |url=http://www.south.hydroguam.net/watersheds-apra.php |website=Digital Atlas of Southern Guam |publisher=Water and Environmental Research Institute of the Western Pacific, Island Research and Education Initiative |access-date=8 March 2021 |language=en}}</ref>
