By Emilie Hackett, Special to the Record – The Magog Lake in Sherbrooke reached its maximal level on Wednesday morning, which forced authorities to open the Rock Forest dam, which holds back the water in the Magog Lake. The dam was opened to its maximum at 10 a.m. yesterday. It will lead to an increased flow in the Magog River. “There are a few areas where it could become problematic,” indicated Christian Laprise, Hydro-Sherbrooke’s director. Sherbrooke’s municipal emergency preparedness organization (OMSC) sent automated messages to the 30-some riverside residences that could be affected by the rising water levels. Sandbags were also distributed as a preventative measure. “One residence is located at the water level. We’ve taken measures to protect it. With the other homes, we have one or two feet of flexibility,” said Stéphane Simoneau, Sherbrooke’s Emergency Coordinator. See full story in the Thursday, April 25 edition of The Record.
