The crazy lake ice did a lot of dock damage this winter but went quickly and quietly off the big lake over a couple of days in early April. For the purpose of official water monitoring, the ice off date for the big lake is April 11, 2015. Four days later, Marge Sidney from the Ministry of Environment conducted level 2 “overturn” water testing for the first time on Lac des Roches. This testing provides valuable water quality information prior to the spring turnover, when the warm water at the bottom of the lake trades places with the colder water at the surface of the lake – commonly called turnover. Lac des Roches turns over twice a year, Spring and Fall. Residents of the lake volunteer their time during the ice off months to regularly monitor the water through several quality test. Data is summarized and analyzed by staff of the BC Lake Stewardship Society and Ministry personnel.
