The Tur in YD 116 elaborates for several pages on the laws of liquids that were left revealed that are forbidden due to the concern that snakes drank from them and poisoned the water. Shulchan Aruch omits the entire discussion explaining that nowadays we do not live near such snakes. However, as the Pri Chodosh Points out, in places where snakes are common these laws do apply and one would have to refer to the Tur in such cases.
