Paulespo, if the Womb was in my back yard filling it a bit with some sand is what I would do. But like you said you can't go wrong just sticking with cleaning and vacuuming the pools. I used to keep a 20 foot, inch and a half pool hose down there hidden in the bushes in a five gallon bucket with a lid to keep the rodents from chewing on it. You just line the inside of the bucket with that size hose and it fits perfectly. Now that the weather is getting hotter people spend less time in the hot pools and more time in the stream. Today I was at Deep Creek with my daughter a long ways downstream from DCHS, fantastic day, such beautiful scenery, and the water temp there was 74 degrees
