“Whole Watershed Approach” in British Columbia: the St. Mary Lake example (Salt Spring Island)

Is this enough? I’m not sure. “British Columbia’s efforts to protect water quality by regulating “end-of-pipe” point discharges from industrial and municipal outfalls have been generally successful, and it is now recognized that the major remaining cause of water pollution is from non-point sources, which pose significant and growing threats to our water resources. Non-point source (NPS) water pollution is subtle and gradual, caused by the release of pollutants from many different and diffuse sources, largely unregulated, and associated with urbanization, agriculture, and other forms of land development.” How do we manage and control contaminants that arrive via the Jet Stream?

Collaborative Watershed Governance on Salt Spring Island: Blueprint for a Resilient Response to Climate Change

Although designed for developing nations, each of five United Nations ‘Water for Life’ targets may guide British Columbians towards greater community resiliency, human health and equity, and ecosystem protection. Released in October 2015, the St. Mary Lake Integrated Watershed Management Plan demonstrates application of the targets to Salt Spring Island (population 10,000).

Shannon Cowan_SSIWPA_trimmed_120p“What makes the plan innovative is its foundation in both strong science, and local socioeconomic values”, claims Shannon Cowan, Coordinator for the Salt Spring Island Watershed Protection Authority (SSIWPA). “During the development of the Plan, many perceptions about St. Mary Lake watershed were challenged as new scientific evidence and information became available.”

Context for Action on Salt Spring Island

“Treated lakewater is the potable water source for more than 50% of the island’s residents,” continues Shannon Cowan. “The toxin-producing, prolonged cyanobacterial blooms of 2011-2013 in the largest Salt Spring Island lake created an acute need for a coordinated, inter-jurisdictional response for water quality issues.”  To address that need, SSIWPA was created in late 2012.

In direct response to the 2015 extreme drought, the SSIWPA has also expanded its mandate to include freshwater supply and demand management.

Blueprint for Science-based Action

SSIWPA established a whole-watershed approach and a structured planning process founded on scientific evidence, coordinated governance that included multi-stakeholder workshops and locals in advisory roles: the outcome is an integrated watershed management plan for St. Mary Lake watershed

George Grams_Chair SSIWPA_120pThe St. Mary Lake Integrated Watershed Management Plan is a result of involvement and participation of residents, stakeholders, and community organizations, as well as the several agencies that constitute SSIWPA, and who care about the long-term health of our precious watersheds,” says George Grams, Chair of SSIWPA. “The Plan gives us the blueprint for the future, including regulations, legislation, research strategies and actions to help us meet our primary objective of improving raw lake water quality.”
