Yes I used to drink out of every fast moving stream and river growing up here but never any lakes, all the creeks in hatchers pass and arctic valley have beavers and I never got it from any of those waters . Even drank out of copper river but damn I was thirsty. I`ve only been using the water filter now for maybe 15 years. The only symptoms I had was the diarrhea and weight loss but it was bad. Daughter drank from same creek and never got it. Lucky me lol.
