spring run
Fish swim upstream
A spring run is a stream or creek fed primarily by natural springs rather than surface runoff.
These waterways typically maintain consistent temperatures and flow rates year-round, making them important habitats for cold-water fish like trout: The spring run stayed clear even after heavy rains.
In some regions, spring run also refers to a seasonal migration of fish, particularly the early movement of certain species upstream in spring.
