I think that was way too fast for a first introduction to a lot of water. Take it WAYYYYY slower next time. First go up to her knees for the first couple weeks and just let her wade/ walk in the water. For a couple WEEKS. Seriously. Water inhalation is extremely dangerous and even if she doesn't drown she could get aspiration pneumonia if water gets in her lungs. Please, please be more careful next time. Some horses enjoy swimming and it sounds like she does like getting wet on a hot day, but please don't ever put her in that kind of situation again. Take it way slower. Just let her get used to walking in the water and just forget about swimming. If she goes out so that the water is just at her back that will definitely be deep enough for this year and really all that she will ever need to cool off. Not saying she will never swim (and not saying that she will) but it's not worth loosing your very trusting horse over it.
