underground stream
Hidden flowing water
An underground stream is a body of water flowing beneath the earth's surface, typically through caves, porous rock, or subterranean channels.
These hidden waterways feed springs and wells, and can carve out caverns over time.
Figuratively, an underground stream suggests a hidden current of thought, influence, or tradition running beneath what's visible: an underground stream of dissent within the party.
