On a hot day, a place to swim on a lake or river looks very inviting.
Those days are here, and so are the concerns about the safety of each swimming hole.
Rocks aside, dangers can lurk in those inviting waters.
Which is why Rogue Riverkeeperand similar programs across the country are helping swimmers out, by testing the water for Swim Guide.
Information on bacteria and several other measurements are compiled and posted online, so people can surf before they take a dip... and maybe avoid a dip altogether.
