| Topic | Aquatic Insects: Richness Index Elk River 1994-96 |
| Caption: Richness is a measure of aquatic insect diversity with higher scores reflecting a healthier community. Harrington (1999) ranked diversity of communities as being high when total taxa exceed 36, but fewer than 26 species represents a non-diverse or unhealthy aquatic community. Elk River scores show a wide range with North Fork Elk River showing a less diverse community indicative of the presence of stressors and Little South Fork stations showing higher diversity and very good aquatic health.
