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

Stream Habitat

This artificial stream provides habitat for species that prefer flowing water to still water. Stream water is typically cooler, clearer and has a higher oxygen level 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 on the landscape extends far beyond their relatively small land area. Along with providing critical habitat, food, and shelter for wildlife, they also reduce damage from floods, are sources of drinking water, filter pollutants, and support economically important recreational and commercial uses.

The 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.
