When we were in Central Oregon last month we visited Fall River. This short, amazingly clear and tranquil river is best know to fly fishermen. Reflecting fall colors, it was a treat for the eyes and heart. Fall River emerges straight from the ground in large springs at its head. Fishermen know this river as a safe source of drinking water.
It has always seemed sad to me that the pristine-looking streams and lakes of the Cascades are often infested with giardia, not to be consumed without boiling or chemical disinfection. It was a real treat to be able to drink directly from the springs of Fall River.
