The Poudre River has many fish that need to live in flowing waters. There are also many ponds along the river that are open for fishing. The fish feed on the algae and plants, the tadpoles and the insect larvae that are in the water. The fish in turn are food for the eagles, the pelicans, and other water fowl.
