This dataset cointains the open accessible data and reports for the FIMP survey carried out in Slocan Lake in 2011. Slocan Lake is one of the few remaining large lakes in British Columbia about which very little scientific information has been gathered to date. It is obvious that comprehensive lake management guidelines cannot be developed without the requisite collection of scientific data which will serve as the basis for any proposals, recommendations and conclusions. Thus, after some research and consultations with representatives of the Regional, Provincial and Federal government agencies, the Slocan Lake Stewardship Society undertook to implement a scientific baseline study, completing a data collection project describing the current state of the lake from an ecological perspective. The recent increase in housing development along the shore of the lake and the concomitant increase in the recreational use of the lake waters strongly suggest that such a project be conducted in order to mitigate any future serious impact upon the lake’s ecology.
