Etymology: Headstreams are the streams where a river begins, the first channels that gather water from springs, seepage and rain before joining into something larger. The word is simply a compound of "head" and "stream," and its pairing is literal: "head" in the old sense of a source or beginning, as in the head of a river or the "head" of a spring. English has used "head" this way for centuries, so the compound describes exactly what it says, the upper end of a flowing system where the water first takes shape. The plural form is the usual way the word appears, since a river system rarely has only one source. Each "headstream" is a stretch of water that feeds the main channel, and speaking of several at once reflects how a drainage basin is built from many small beginnings rather than a single spring.
