This report assesses the water quality of Desolation Sound, a marine inlet on the west coast of the BC mainland opposite Campbell River on Vancouver Island. It's assessement was conducted in selected embayed areas within the Desolation Sound area. The boundaries of the sound are not precise, but for the purposes of this report, Desolation Sound describes the marine waters east of Cortes Island, extending from Okeover Inlet in the south to Raza Passage in the north. However, this report will focus primarily on the southern portion of Desolation Sound, in the area between West Redonda Island and the Malaspina Peninsula, and bounded to the north by the southern end of East Redonda Island. This area is a popular destination for recreational boaters, and includes the Desolation Sound Marine Provincial Park, Tux'wnech Okeover Arm Provincial Park, Roscoe Bay Provincial Park, and Malaspina Provincial Park. As well, shellfish farming and harvesting are important economic activities throughout the Sound, and a large number of mariculture tenures have been issued for the area. As the primary water uses for the Desolation Sound are for recreational purposes, mariculture and aquatic life and wildlife, the designated water uses are primary-contact recreation and aesthetics, the ability for shellfish growing and harvesting and marine aquatic life. These are the uses that are most sensitive to impacts that might occur to marine water quality, based on existing activities within the watershed. Potential impacts to water quality in Desolation Sound are primarily linked to untreated sewage discharges from pleasure craft and residences, as well as from possible fuel spills from pleasure craft or at refilling stations on private docks. Increases in upland development could lead to increased non-point sources of pollution to marine waters. The project consisted of five phases: water quality data collection, gathering information on water use,
determination of land use activities that may influence water quality, assessment of water quality based on land use influences, and establishment of water quality objectives. This report is based primarily on data collected between 1999 and 2004, although water quality data from as early as 1980 is also considered.
