Salt water will evaporate first. Salt takes up space so to speak and there's less "water" to evaporate and so it seems to evaporate faster.
water evaporate 2 to 3 inches every three days if the temperature is above 90 degree each day.

In cold weather, water in a pond usually freezes first at the surface before freezing spreads downward. It freezes at the edges first because the edges lose heat more quickly than the deeper parts of the pond, making it easier for the ice to form there.
Anton Van Leeuwenhoek was first scientist who studied pond water and observed , discovered and described many organisms in 1773 .

Tap water typically needs to sit for at least 24 hours before being added to a koi pond to allow chlorine to evaporate. If the water is treated with a dechlorinator, it can be used immediately. Additionally, it's important to ensure that the temperature and pH levels of the new water match those of the pond to minimize stress on the koi. Always check for any contaminants or chemicals in the tap water that could harm the fish.
Solution of Pond Water= Oxygen + Water
Pond water is not a pure substance.
