(Prepared July 2018) Mainstreams Environmental Society partnered with the Slocan River Streamkeepers to conduct baseline water quality monitoring in Lemon Creek during two years (2016 & 2017). Lemon Creek was identified as a priority for monitoring, since it had high fisheries values, and is in an area with the potential for increased development pressures. In addition, there was concern about effects from a fuel spill that occurred up the creek in 2013.
Monitoring was conducted at a site near the confluence with the Slocan River. Three components were monitored: benthic macro-invertebrate community using the reference model provided by CABIN, water/sediment quality, and hydrologic characteristics (i.e., velocity and stream flow). Only one parameter, pH, exceeded guidelines for the protection of aquatic life, and only in one sample. All others met the aquatic and drinking water guidelines. No indications from the water/sediment quality or the hydrometric results of the habitat being impaired.
Through this project 47 species-at-risk were confirmed in the Slocan Watershed in 154 locations. An additional 11 species that have a high potential to be at-risk were identified, as well. The species include vertebrates, invertebrates, reptiles, amphibians, vascular plants and non-vascular plants. This represents a considerable increase in the number of species-at-risk known to exist in the watershed, although several species on the list are well documented but are not tracked, or do not show up, on CDC data.
Lotic Environmental Ltd. completed a review of data collected by the Slocan River Streamkeeper Society at Lemon Creek Site 3, through the Columbia Basin Water Quality Monitoring Project. This review included analysis of data collected in 2016 for the four components of the project: 1) water quality data, 2) continual temperature data, 3) hydrometric data, and 4) Canadian Aquatic Biomonitoring Network data. Lotic Environmental’s objective was to conduct a quality assurance/quality control review of data, compare water quality results to applicable guidelines, interpret results, and make recommendations.
Kat McGlynn and former Slocan River Streamkeepers chair Rhia Mackenzie undertook a project to learn about the dietary habits of the river otter. Here are some results of their project, provided in poster form. (Use the “zoom” or + function to enlarge the display.)
This report – chiefly involved with the Canadian Aquatic Biomonitoring Network (CABIN) project – presents research, analysis, and discussion concerning 11 sample sites on Slocan River and tributary creeks. Water-quality and aquatic ecology: benthic community composition, water-quality testing, sediment-guideline acceptability assessment (guideline review), etc.
Rainbow trout habitat throughout the Slocan River was assessed using aerial photography, contributing to the development of a database of relevant biological and physical. This study is intended to enable the identification of sites with the greatest potential for the return of rainbow trout productivity.
An initial inventory identified over 80 side channels, major and minor, throughout the Slocan River, with side channels being a critical component to rainbow trout ecology. Some channels were fully functioning, some not. Out of a total of 45 “significant” channels, 10 were selected for further investigations (3 fully functioning to act as benchmarks, 7 having potential for restoration).
This reports on a study undertaken in an effort to better understand fish population dynamics and links between numbers, age class and species of fish in relation to food source, a study of benthic macroinvertebrates, the fishes’ main food source.
This reports on the monitoring of the rainbow trout (Oncorhynchus mykiss) population in the Slocan River. A spike in population in 2006 was indicated, driven by the production of trout in the Lemon Creek index site. By 2007, trout from the Lemon site had redistributed throughout the river, causing a reduction in the number of trout in the Lemon site, while other sites in the river experienced an increase in numbers. By 2008 reduction in the overall number of trout was indicated, returning to population levels experienced pre 2006.
Concerned with the Slocan River fishery, this final report published in June 2000, at the end of extensive research by the Fish in the River Working Group, became the impetus for the formation of the Slocan River Streamkeepers Society. The report was developed in conjunction with Selkirk College and funded by Fisheries Renewal BC.
