Lake Health Overview 

The waters of Kahshe and Bass Lakes are fed through streams and peat-like materials, giving them a tannin-rich tea colour.  Kahshe Lake has long had a reputation for healing, and was formerly known as Kah-she-she-bog-a-mogmeaning Lake of Healing WatersJust as tea bags are sometimes used for reducing swelling and soothing pain, cuts and burns seem to heal quickly in Kahshe Lake. 

Myths aside, as recreational property owners and public users of the lake, we are naturally concerned about the quality of the water now and for the future. This concern was clearly identified in a recent questionnaire via the Love Your Lake Program which was undertaken in 2019 with the support of the KLRA. Water quality was the single most important issue identified for both Lakes. As several respondents to the questionnaire indicated that they were not aware of work undertaken to determine water quality over the past 35+ years, it was apparent that a more concerted effort was required to improve the communication of the environmental findings that are documented on the KLRA’s web-page and in periodic Krier articles. Accordingly, the KLRA web-site has been re-designed to make this work more transparent and accessible. A brief overview of what is provided in the main tabs and sub-tabs is summarized below:
