It's been a long held aspect of my camping mantra to avoid contact with
water in lagoons.
These sometimes attractive appearing waterholes are potential deathtraps
because of the pollution of the long-standing & stagnating non flowing water.
The water is especially prone to enormous proliferation of bacteria and organisims
due to the fact as previously mentioned but additionally largely due to the heat of the water
and the high possible percentage of animal waste and rotting vegetable matter.
As the time progresses and evaporation concentrates the soup, the dangers multiply.
Blow me down, but I see new arrivals rushing to set their crawchie traps to
catch these critters for human consumption!!!
If the water isn't cool and FLOWING, and passing thru known potentially low pollution
areas upstream, you could well be dicing with some very serious sicknesses.
And keep the kids out of it - little hands don't understand the dangers.
Think about it first!!
