Natural swimming pond in southern Nevada feasible
I live in Clark county Nevada, where heat is a constant for a huge portion of the year. I love the concept of Natural Swimming Ponds (NSP) sometimes called Recreational ponds. The water quality is maintained with out the use of chemicals. The trouble is I can’t find examples of working NSPs in my climate. Given this will the water quality levels be a challenge to maintain. Is it possible to achieve a working natural swimming pond? And if so, How? What swimming zone to regeneration zone percentage is the sweet spot for clean water? Is a pump essential; and if so, how quickly does the volume of the pond need to be recirculated through the pump?

I would at least install a pump to pull water out of the pond and cascade it back into the pond some how to create some aeration rather than leaving it stagnant. A small solar set up make work out for you.
That’s pretty much my thought, is the water will need some kind of aeration. But given my hot climate it’d would be such a disaster if I couldn’t keep it clean.
You could send the water through some type of charcoal and/or sand medium before cascading it back into the pond.
You’re going to need aeration. A waterfall or a fountain, running continuously all the time. That moving water will have a downside too: increased evaporation. You’ll need a way to provide makeup water to maintain a consistent water level in your pond.
With no chemicals (mainly chlorine), stuff is going to grow in the water. You will not have pool-like clear water, you’ll have water like a lake or pond. Your challenge will be keeping the correct stuff growing and in a good balance.
I’d suggest looking at what the people that maintain koi or lily ponds do, or the planted aquarium people (I like barrreport.com and have known Tom for a long time). You’ll need some plants, and ideally some fish too. Keep a good balance and mix in the right nutrients and you can have a nice pond — and you can “swim with the fishes” :-)
I’ve been interested in this subject for a while. There are many examples I’ve seen of natural swimming pools in hot environments.
You need a ratio of 1-1 swimming area to wetlands filter and you’ll definitely need a pump.
