The U.S. Army Corps of Engineers is delaying the opening of Plymouth and LePage campgrounds. The campgrounds, which were originally scheduled to open to the public on Tuesday, will now open May 9. The Corps of Engineers says it is experiencing challenges providing recreation activities for the public this year due to what it termed resource constraints. In a statement, the Corps says the delay allows them to ensure campground facilities comply with health and safety standards for the upcoming recreation season. Corps’ Portland District Natural Resources Management Director Melissa Rinehart says visitor well-being is their priority, so they are delaying the campground openings to ensure staff can provide safe experiences for visitors.
