Why do some rivers run red, brown, or yellow after heavy rain?

Quick Answer
Heavy rain can wash soil, clay, and iron-rich sediment into a river, changing its color. The water becomes muddy or stained until the sediment settles or is carried away.
The Full Story
Rainstorms can erode bare ground, riverbanks, and hillsides, sending large amounts of suspended sediment into nearby streams. Fine clay makes water appear brown or yellow, while iron-rich particles can give it a reddish tint. Fast-flowing floodwater keeps the material suspended, so the river may stay discolored for days. This is common after storms, landslides, and construction runoff. In some places, natural weathering of red soils can keep rivers colored even without a storm.
