Larson Creek Watershed
Summary
Physiography:
- Eighteenth largest watershed in West Vancouver
- Bordered by Whyte Creek and Nelson Creek of the Nelson Creek watershed to the north and east in West Vancouver, BC
- Originates on Arbutus Plateau, southwest side of Black Mountain
- Discharges into Larson Bay
- Cobble beach at mouth in Larson Bay Park
- Several hundred metres of creek upstream of mouth has forested riparian areas and no culverting
- Low impervious area in watershed, small urban influence
History:
- Named for Pete Larson who owned District Lot 771 from the west end of Eagle Island to Garrow Bay from 1902 to 1927. Mr. Larson also owned the North Vancouver Hotel on Lonsdale and the old Canyon View Hotel, above the present Cleveland Dam. The site of the present Gleneagles Golf course was cleared and planted with an apple and pear orchard, hay field and vegetable garden.
- Labelled Dodds Creek on old government maps
- Horseshoe Bay area was logged beginning about 1895, Black Mountain logged in 1899
- Water supply use began in 1911 for the Larson house, garden and livestock. Currently used by the municipality for irrigation.
- Developed as residential area and golf course in 1927. Golf course sold to the municipality in 1958
Watershed Use:
- Residential: small urban influence
- Park: Larson Bay Park
- Recreational: Gleneagles RecCentre, Gleneagles Golf Course, Baden-Powell Trail

- Automobile transportation, hydro lines and substation, B. C. Ferries Horseshoe Bay Terminal ticket booths and car waiting area
- Water licence held by the District of West Vancouver to use 36 acre foot per anum for purpose of watering
Concerns:
- Morphology:
- culverting at Upper Levels Highway and 4 other locations downstream through golf course, bridge in golf course
- channelization of creek and loss of tributaries through urban area
- Water Quality:
- altered through proximity to urban golf course and Upper Levels highway and ferry ticket waiting area
- Possible future development in upper watershed and associated problems, including:
- increase in imperviousness
- loss of wetlands and tributaries
- construction of storm drain network resulting in altered water quality and quantity
- encroachment into riparian zones
- tributary channelization, bank alteration
- increased erosion into creek
Key Interest Groups:
- Municipal: District of West Vancouver, District Parks Department
