Q: Why are insects crawling over this page?
A: These benthic macroinvertebrates (bottom-dwelling stream bugs big enough to see without a microscope) tell us a great deal about water quality.

Sierra Streams Institute is a watershed monitoring, research, and restoration group based in Nevada City, California, in the Sierra Nevada foothills. Our mission is to promote community stewardship and scientific knowledge of watersheds through monitoring, research, restoration, and education. Founded in 1995 as Friends of Deer Creek, SSI has grown to become an important voice in the regional scientific community—but we are still proud to call Deer Creek our home watershed.
