Stop 10: Stream Habitat

Flowing stream built into environment
The DRLC courtyard features a living stream habitat.

This artificial stream provides habitat for species that prefer flowing water to still water. Stream water is typically cooler, clearer, and contains more oxygen than pond water, and some fish feed by facing upstream and catching what flows by. Especially in the desert, where water is rare, the importance of stream systems extends far beyond their relatively small area. They provide critical habitat, food, and shelter for wildlife, reduce damage from floods, are sources of drinking water, filter pollutants, and support economically important recreational and commercial uses.

This stream is lined with rubber. It is fed with rainwater stored in a steel water tank nearby. A pump generates flow and the water is recirculated. The stream channel is six feet deep in some locations. These deep areas are stacked with rock-covered crates. The crates provide suitable habitat for desert-dwelling fish and enable the stream to meet local safety standards for artificial water bodies.
