COEUR D'ALENE, Idaho - Authorities in northern Idaho say the worst flooding is past and they're now turning their attention to possible contamination and debris left behind as waters recede.
Kootenai County Sheriff's Lt. Kim Edmonson says most rivers have crested but Lake Coeur d'Alene is still about seven feet above its normal summer level.
Officials are discouraging people from swimming or drinking lake or river water until they can test waters for harmful contaminants and debris.
Possible sources of contamination include flooded campground bathrooms, erosion lead deposits from the Silver Valley, agricultural operations and saturation of individual sewage disposal systems.
While falling water levels offer hope over the weekend, flood observers are not certain flood dangers have completely passed in the region.
Edmonson says additional snow melt when temperatures are expected to rise next week may cause water levels to rise again.
