Rainbow trout like to inhabit cold headwaters, creeks, rivers, cool lakes, estuaries, and oceans. Some genetic strains of rainbow trout will live in up to all of these habitats in their lives if available. Good trout stream habitat is complex with riffles and pools, submerged wood, boulders, undercut banks, and aquatic vegetation.
