Before you go
Many reservoirs are drinking-water supplies with no swimming or body contact. Look for a designated swim beach.
Green, scummy or paint-like water can be a toxic blue-green algae bloom. Keep kids and dogs out and check the county advisory.
Boat launches often need a day pass or inspection for invasive mussels, and anglers 16 and older usually need a state fishing license.
