It's fine for a quick dip, but you'll REALLY want to take a dip in the river afterward. The river here hasn't seen any true high water in probably over 5 years. That means that radium hotsprings hasn't been flushed in all that time. All that "silt" in the pool is actually dead skin, the moss is out of control and some of the hair algea looks like green rastafarian mops! Just don't wear your kayak gear into the water. Imagine all the bacterial colonies growing in your drytop from that murky warm dead-skin water. Poly PEW!
"So in two seconds, away we went, a sliding down the river, and it did seem so good to be free again and all by ourselves on the big river and nobody to bother us." -Mark Twain (The Adventures of Huckleberry Finn)
