Colquitz River Watershed

The topography of Colquitz watershed is generally quite flat, with an average gradient of 0.6%. The headwaters are at an elevation of 91m above sea level, and most of the creek itself is an average of 21m. The watershed was formed as a result of glacial action, and is formed of four basic bedrock types: Vancouver volcanics, Wark gneiss, Colquitz gneiss and granodiorite. Moving from the highest parts of the watershed to the mouth at Portage Inlet, the geology changes from Cordova sands and gravels to Colwood sands and gravels, to marine clay. Intermittent bedrock outcrops are present in the watershed, with generally fewer in the sub-watersheds of Swan, Blenkinsop and Durrell creeks.
