Hydrography
Victoria Harbour comprises the Outer Harbour, Middle Harbour, Inner Harbour, James Bay, Upper Harbour, Selkirk Water, Gorge Waters, and Portage Inlet. Just to the west of Victoria Harbour is the Esquimalt Harbour.
The active portions of Victoria Harbour that can accommodate large and mid sized vessels (Outer, Middle, Inner, and Upper) are spread along 4 km (2.5 mi; 2.2 nmi) of estuary. The width of the active harbour goes from 0.74 km (0.46 mi; 0.4 nmi) out at the Ogden Point breakwater entrance down to 137 m (449 ft; 0.074 nmi) along the Middle Harbour then widens out in the Inner and Upper Harbour areas. Harbour depths vary from 6 m (3.3 fathoms; 20 ft) up to 20 metres (11 fathoms; 66 ft) in the Inner Harbour.
