Slocan River Community Water Monitoring 2019


Slocan River Community Water Monitoring 2019 was designed to monitor the effects of climate change and human factors on aquatic and floodplain ecosystems.  As well, to monitor effects on community drinking water sources (water quality and availability).
These ecosystems provide important habitat for many species including various species at risk and also provide residents of the Slocan Valley with clean drinking water. The data we collect this year will build on our knowledge of water quality from studies over the last 25 years, and allow us to identify any long term trends or changes that may have occurred.
This project addresses four main issues:
1) Rising water temperatures and its effect on aquatic ecosystems, specifically Rainbow Trout and Bull Trout, 
2) Potential effects of sedimentation caused by stream bank erosion on water quality and aquatic species downstream of the landslide on Little Slocan, 
3) Effects of climate change on community water sources, 
4) The recovery of aquatic life in Lemon Creek.
Work that has been completed so far is installation of water temperature logger at three locations along the Slocan River as well as one in Lemon Creek and one in Winlaw Creek; collection of turbidity samples above and below the Little Slocan slide; stream flow measurements at four smaller creeks that are used for drinking and irrigation water; CABIN assessment of Lemon Creek; and E.Coli sampling of Winlaw Creek. Data will continue to be collected and compiled over the winter months and will be analyzed in spring.
Thank you to our funders, CBT and SIFCo, for making this possible and for supporting us to do this important work.



Water Monitoring on Springer Creek


On Wednesday August 15th, 2019, Slocan River Streamkeepers’ Shanoon Bennett and Dominique Monnier hosted a community event to collect water quality data on Springer Creek, in Slocan B.C, using the Hach Test Kit granted by the Columbia Basin Watershed Network Society. A total of seven youths, and eight adults participated in the event and learned about why it is important to monitor water quality on local streams and how to do it.

Springer Creek flows into Slocan Lake and is important habitat for trout who depend on cold water for spawning and rearing, and for invertebrates- the bugs that feed the fish. Volunteers measured water temperature at 13.4 C, dissolved oxygen at 10 mg/L, and pH at 7.3. Results show that Springer Creek is currently well within optimal limits for fish and invertebrates. Furthermore, it is interesting to note that water temperature in Springer Creek was 6.3 C cooler than the Slocan River which was measured at 19.7 C on the same day. This is important because temperatures above 20 C can be lethal to juvenile trout meaning that they depend on cold streams like Springer Creek for refuge during the hot months of summer.

A big thank you goes out to CBWN and CBT for the Hach kit and to all those that attended and made this event such a great success.



Water Monitoring

Previously in the Slocan Valley, citizen water monitoring had been instigated and carried out in connection with the forestry concerns of the Slocan Valley Watershed Alliance.  In 2006, Valley residents were invited by Environment Canada to participate in a program initiated by that federal agency.  It’s called the Canadian Aquatic Biomonitoring Network (CABIN).

CABIN’s focus is on aquatic insects.  While CABIN becoming established in the Kootenays was the starting point for Streamkeepers’ water monitoring, the programs under our banner have since expanded to encompass water-chemistry,  temperature and microbiological monitoring, as well. In addition, we are working with local scientists to develop a biomonitoring assessment tool for West Kootenay Wetlands.

For most of our history, our focus has been on the main Slocan River.  Since the spill of aviation fuel in Lemon Creek in 2013, we’ve had a creek-monitoring project in that stream.  We also have an ongoing water monitoring project in Springer Creek.  Among our current interests are the changes due to warmer water temperatures, suggesting the need to include the bacteria testing that we now do.
