From September 4 – 7, 2018, Living Lakes Canada (LLC) and the BC Lake Stewardship Society (BCLSS) enlisted the help of several volunteers and local residents to collect lake quality data for five East Kootenay lakes as part of the BC Ministry of Environment and Climate Change (MOECC)’s ongoing provincial lake monitoring program.
Water quality data is collected annually by MOECC, in both spring and fall, from lakes throughout the province. This year, LLC and the BCLSS were asked to assist with sampling in the East Kootenay region, including Windermere, Columbia, Whiteswan, Premier and Moyie lakes.
MOECC staff taught volunteers the sampling protocol used for the fall sampling project. First, temperature and dissolved oxygen were measured in the lakes using a 100-metre sonde. This data was used to determine the different “layers” of water that would be sampled. Next, composite water samples were collected to be analyzed for chemistry, nutrients, chlorophyll a, phytoplankton, zooplankton, and mussel larvae. This process took the team of volunteers between 2-6 hours for each lake that they sampled.
Monitoring for all of these parameters helps summarize the current ecological productivity of a lake, which is important knowledge for water quality and fisheries management. By monitoring every year in spring and fall, the lake data will show if and how these lakes may be changing over time.
This project was a great example of collaboration between community and government, and demonstrated how community-based water monitoring groups can play a more active role in provincial water monitoring programs.
Thanks go out to Norm Zirnhelt with the BCLSS for training the LLC staff and directing the fall field sampling. Special thanks also to the volunteer boat drivers who committed their time and efforts for this lake sampling: Gavin Jacobs (Lake Windermere Ambassadors), Dave Rae (Columere Park Community), Tracy and Glenn Flynn (Columbia Lake Stewardship Society/East Kootenay Wildlife Association), and Mike Labrie (Eagles Nest RV Resort).
