There are several definitions which are not entirely compatible with each other, but they have more similarities than differences. Edge cases are hard. See, for example: https://lakes.grace.edu/ponds-vs-lakes-whats-the-difference/ https://www.lakemat.com/whats-the-difference-between-a-lake-and-a-pond/ https://www.des.nh.gov/organization/commissioner/pip/factsheets/bb/documents/bb-49.pdf https://www.lakescientist.com/lake-facts/how-lakes-differ/ Most of them agree that lakes have aphotic zones (deep areas that receive no sunlight, preventing plants from growing there). But wave height, uniformity of temperature, and area of water may play a part. And, of course, there's what the locals call it. > > Is there a conceivable scenario where a data consumer or renderer would > care about the distinction between these two tags? > Renderers will probably treat them identically A limnologist would find the distinction useful. There is also a distinction between pools and ponds. However, since pools are supplied by a spring or a stream, most can be distinguished by other water=* occurring in conjunction with them (a lot of the ponds I've mapped are actually pools). https://www.askdifference.com/pool-vs-pond/ -- Paul
