About Quamichan Lake

The Quamichan Watershed Stewardship Society (QWSS) — also known as “Quamichan Stewards” — is a registered charity whose mission is to encourage and support activities to promote the watershed health and water quality of Quamichan Lake. QWSS was formed as a sub-committee of the Cowichan Land Trust in the spring of 2006 to respond to the continuously declining health of Quamichan Lake. The Quamichan Watershed Stewardship Society is a registered Charity (BN 82868 0892 RR0001).

Quamichan is the largest lake in North Cowichan

  • The length is 3.1 km and width 1.2 km

  • The Lake Volume estimate: 13,770,000,000 liters

  • Estimated turnover: once per year

QWSS Focuses

Agriculture & Farm Fields

  • Addition of zeolite to animal feeds - reduces runoff and makes manure more efficient to use

  • Using zeolite as a nutrient trap at the edge of fields

  • Plant trees and shrubs at the edge of fields to trap nutrients

Human Activity

  • Including garden and lawn fertilizer, hard surfaced paths and drives, lack of rainwater storage on site.

  • Some of this can be impacted by education.

  • Could change zoning to reduce runoff from sites

Zoning & Regulatory Changes

  • Runoff management built in to zoning and building permits

  • Charging for storm water runoff - combine stormwater with sewer utility

  • Increase the use of row or townhouse development - reduce footprint and related soil disturbance and leave more room for runoff water treatment

Construction Site Management

  • Change the timing of excavation and construction to the summer

  • Do a better job of reducing runoff

Erosion

  • Erosion from runoff creeks, ditches beside roads and channeled water draining large areas of development

  • Review the maintenance practices that contribute to erosion i.e. cleaning all vegetation

  • Add foliage and boulders to slow down the streams

Expansion of Sewered Area

  • Be more active with sewer expansion

  • Require septic inspections or assessments to ensure they are working
