gravel beds
Rocky stream bottoms
Gravel beds are layers or deposits of loose, rounded stones, typically found along rivers, streams, or lakeshores where water has sorted and deposited sediment.
They serve as spawning grounds for fish like salmon and trout: The creek's gravel beds are critical habitat for spawning steelhead.
In construction and landscaping, gravel beds provide drainage beneath foundations, patios, or gardens.
