The following studies and reports about the Gorge Waterway, Portage Inlet and their surrounding watersheds are provided to assist in gaining a better understanding of these waterways. Several historical reports are also provided.
In 1997, a two year bird survey of Gorge Waterway, Portage Inlet, Esquimalt Lagoon, and Esquimalt and Victoria harbours was initiated. Every two months observers enumerated birds using the harbours and waterways, and results were compiled and presented on the Harbours Atlas (now part of the CRD Regional Map). Here is the original report:
Shepard, M.1999 -Victoria and Esquimalt Harbours Bird Censuses 1997-1999
Starting in 2019, the CRD Harbours Program is repeating this survey over a two year period with monthly surveys in all harbour areas.
