Macroinvertebrate Monitoring

800 532 Stroud Water Research Center

(Note: the formal project title changes from year to year depending on which rivers are monitored.)

These projects use aquatic macroinvertebrates such as mayflies, stoneflies, and caddisflies to provide assessments of current water quality in these streams and rivers. Where long-term data are available, the most recent conditions are compared to historical conditions.
