While a toxic advisory remains in place for Blue Rock State Park, it's hoping people will still come and use its hiking trails and campgrounds.
The Ohio Department of Natural Resources says the state park's store is receiving water from outside sources. It also says that water fountains and the campground's shower house have been re-opened.
The state park's water treatment station did close after unidentified blue-green algae was discovered in the lake. Park rangers are still asking that people avoid contact with that water source.
