KEARNEY- Johnson Lake has tested positive for E. coli bacteria. When E. coli bacteria levels test above 235 colonies/100 ml, a Health Alert is not issued. However, conditions are at a high risk to human health when swimming. Considering the more rapid changes in bacteria conditions, signs are not posted with these higher levels. Although people should be aware of beach conditions and use their own judgement as to whether they use a listed water body.
If you find the levels are above the risk-based guidelines, avoid any situation that could cause you to swallow lake water, if you have been in contact with lake water, shower afterward, and if you have been in contact with lake water, wash your hands before eating.
