Trillium Creek Watershed
Summary
Characteristics
- Trillium Creek is a tributary of McCartney Creek in Blueridge
- The headwaters of Trillium appear to be culverted so that the first visible sign of the creek is as it flows out of a culvert under the path between Medwyn and Dunrobin. Trillium flows south between Emerson Court and Medwin Place and Walpole Crescent through a relatively natural forested area. South of Emerson Place, Trillium enters a deep forested ravine and flows southeast to join McCartney
- The Trillium Creek Watershed is bordered by the Blueridge Creek Watershed to the west and the McCartney Creek Watershed to the east
- The Trillium Creek Watershed is about 13% impervious surface (GVRD, 1999)
Watershed Use
- Fish: Cutthroat
- Wildlife: besides providing habitat for various species of reptiles, amphibians, birds and mammals, the riparian corridor serves as a travel corridor.
- Vegetation: Coastal Western Hemlock, dry subzone.
- Parks: McCartney Creek Park, Trillium Park
- Residential: the area surrounding Trillium Creek is primarily residential
- Schools: Seymour Heights Elementary, Trillium Elementary
Concerns
- 5 storm drains flow into Trillium
- Trillium is culverted in its upper reaches and possibly in its headwaters
- High level of suspended sediments noted in the water during preliminary watershed assessment in spring, 2001 (NSSK, 2001)
Watershed Projects and Good News
