North Montgomery County Lake rescue boats were responding to an overturned boat off of the south end of Walden where a boat had flipped upside down, ejecting everyone onboard. First responders on-scene confirmed 10 people were in the water. They were all safely out of the water by the time fire boats arrived, thanks to the swift response of Pct. 1 Constable Cash’s Lake Patrol. Law enforcement and fire / EMS are having a busy holiday weekend on Lake Conroe, which always attracts a lot of extra visitors for the Fourth of July.
