Depth check
A planning aid. Not a certification or a forecast.
Pool swimming is the controlled version of a human skill that used to be learned in rivers and harbours. Chlorination, lane ropes and depth markings turned a public-health project of the late nineteenth century into the default first water classroom.
World Aquatics (formerly FINA, founded 1908) still writes the competition rulebook, but most pool hours are not racing: fitness laps, school lessons and municipal recreation. The same 25-metre basin can hold a masters set at 06:00 and a learn-to-swim class at 16:00.
This atlas treats the pool as infrastructure — access, etiquette, coaching lineages and the gap between a public bath and a FINA-standard 50-metre hall — not as a race preview. Open-water and competitive chapters sit beside it.

Frequently asked questions
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
What water temperature is typical?
Recreation and lessons often sit near 27–29 °C. Training pools may be cooler, around 26–27 °C. Therapy pools run warmer.
Who writes the sport rules?
World Aquatics (the former FINA) publishes the competition rules. Local pools add house rules on laps, diving and children.
How long does learn-to-swim usually take?
Many agencies plan 8–12 group lessons for basic independence, then months of practice. Age, prior water time and class size change the curve.
Are public pools chlorinated everywhere?
Chlorine or bromine residuals are the common disinfectant in municipal basins. Some venues use ozone or UV as a supplement, not a replacement for a residual.
What does circle swimming mean?
In a shared lane, swimmers keep right (or follow the posted direction), pass in the middle, and leave space at the wall. It is etiquette, not a race rule.
Is pool swimming a certification sport?
No. Racing has memberships and time standards. Lessons have instructor certificates. Recreational lap swimming does not require a card.
How does this differ from open water?
Walls, lines and a known depth remove current, swell and sighting. Open-water chapters cover the skills the pool cannot teach.
