The Memorial Day holiday weekend is just days away and many people will enjoy some or part of it at Grand Lake St. Marys.
If you're looking to camp at the state park you may be out of luck as all of the reserveable sites are taken.
There are a few walk-in sites available, but probably won't be for long.
While the weather may be cooler, a bigger concern is the posting of toxic algae warnings that went up at state park beaches Thursday afternoon, urging visitors to avoid with the water.
State park manager Brian Miller doesn't think the warnings will affect campers all that much.
The toxic algae warnings that were put up this year came later in the spring than they did last year.
There are no plans for any more alum treatments, but dredging continues and the implementation of solar bee aerators on the lake are working to reduce the phosphorus that feed the toxic algae.
