Stay Safe

Municipal staff should inspect municipal bridges, dams, and culverts for debris blockages.
The public is reminded to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses.
This message will remain in effect until noon on Monday, June 26, 2017. Updated flood messages will be issued as conditions develop.
