Not only does the water of the SRP canals help people live in the desert, but it also employs a very important contributor to the community: the white amur fish. Now, you might not immediately think of fish as being important to living in the desert, but this specific kind of grass carp plays a key role in ensuring the water flows smoothly throughout the canals.

Since the canals are surrounded by a major metropolitan area, they tend to end up with some blown-in debris and garbage from city life. This led one of our listeners to ask if it's safe for the fish to be in the canals, and who takes care of the trash that finds its way into them.

This week on Valley 101, a podcast by The Arizona Republic and azcentral.com, we hear from a senior environmental scientist from SRP who explains the important job the white amur fish does for metro Phoenix.
