The prevailing theory is that streams warm as they travel downstream, from their cool and bubbly mountain beginnings to the slower and warmer winding rivers in flatlands. While that may be true for some rivers, many will actually have cooler sections where tributaries or underground springs join the main river, and coastal streams can be cooler where they empty into the ocean due to a prevalence of cooling fog.
