BOISE -- Lots of Idahoans will be looking for a place to cool off this weekend as temperatures are expected to top 100 degrees around the Treasure Valley.
The Idaho Department of Environmental Quality is warning the public to stay away from the Robie Creek Beach at Lucky Peak Reservoir after excess levels of E. coli bacteria were found in the water during recent water quality monitoring by the U.S. Army Corps of Engineers.
Officials say the bacteria levels are in excess of state water quality standards. E. coli in the water indicates the presence of animal or human waste, and that pathogenic microorganisms may be present and pose a threat to public health. If ingested, the microorganisms can cause diarrhea, fever and vomiting, particularly in infants, small children and the elderly.
DEQ advises people to avoid activities like swimming and wading in the water that could result in ingesting the reservoir water.
The source of the bacteria is unknown. Routine monitoring will continue at the beach to assess the bacteria levels. This same situation occurred at the Robie Creek Beach last summer.
Recreationists are urged to use other beaches at Lucky Peak Reservoir such as Barclay Bay or Macks Creek Beach.
