PROJECTS OF THE BASIN SOCIETY
Over the past decade, the Basin Society has collected a large body of technical data and literature,
which was required to develop the necessary scientific baseline of the Shawnigan Lake watershed
for the purposes of credible knowledge, good judgement, and long-term decision making.
The Shawnigan Basin Society is currently focusing on several initiatives.

COLDWATER
EURASIAN MILFOIL REMOVAL PROGRAM
Change Approval and Notification
(Changes In and About a Stream)
To conduct the removal process outside of the usual summer work window because that is when the water is cold enough to limit the spread of milfoil due to fragmentation followed by vegetative reproduction.
OBJECTIVE: Maintaining the low productivity oligotrophic status of Shawnigan Lake by removing the invasive Mryiophyllum spicatum (Eurasian watermilfoil) with its accumulated nutrients.

Ecosystem-Based Conservation Plan
A comprehensive report underpinning the direction of watershed governance
|
This report takes a progressive approach to watershed management by looking at the watershed holistically. The value for nature to provide economy is dependent on the health of the watershed. The integration and implementation of the plan for Shawnigan residents will largely depend on the cooperation between private land owners and the interconnected and interdependent integrity of their various connective properties.

A Master's thesis on the vegetation changes between 1984 and 2014 in Shawnigan Lake
|
This study mapped the vegetation changes between 1984 and 2014 in southern Vancouver Island using various methods, including the Normalized Differential Vegetation Index (NDVI) derived from satellite data. Very detailed analyses in the Shawnigan Lake Watershed during those 31 years provide information on vegetation cover, urban sprawl, and remaining ecological corridors. As climate in the region continues to change and anthropogenic pressures build-up, mapping the changing landscape becomes critical for the adaptive management of the basin.

Shawnigan Lake Foreshore Inventory 2015
A baseline study to assess the riparian vegetation at the shoreline of Shawnigan Lake
Jenny Berg, BSc |
The objective of this project was to assess the ecological integrity of the riparian zone of Shawnigan Lake and the condition of the immediate foreshore. Over 500 pictures were stitched together and coded to document the current state of the Shawnigan Lake foreshore. The information is presented by sub-basin and highlights five categories of impact. |
In an effort to engage lake stewardship the following information is intended to be a meeting point for citizens to assess what can be done to help protect the water quality in Shawnigan Lake.

Synthesis Reporting
Amalgamating approximately 30 documents to produce one comprehensive report
This informative paper, synthesized by SBS Director Dr. Linda Gregory, summarizes both historical and present land use literature pertaining to the Shawnigan Lake watershed while focusing on their hydrological implications. The paper closely examines water quality, lake limnology, water chemistry, and sediments.
