A macroinvertebrate biotic index for water quality analysis in the southwest Missouri Ozarks based on data from the James, Elk, and Spring River systems
Youngsteadt NW and Witherspoon JT. 1986. A macroinvertebrate biotic index for water quality analysis in the southwest Missouri Ozarks based on data from the James, Elk, and Spring River systems. City Utilities of Springfield. Springfield, MO
A biotic index was devised that uses riffle invertebrates to classify stream water quality in southwest Missouri relative to nutrient enrichment. To create this index, the invertebrate fauna was divided into about 85 taxa, each assigned a water quality number to represent its water quality preference. These numbers are assigned based on extensive chemical, bacteriological, invertebrate data gathered bythe Missouri Clean Water Commission from the James, Elk and Spring River Systems in 1964-65. The biotic index for a given location may range from 0-5, and is simply the average water quality number for all of the individuals in a sample. The resulting biotic index correlated well with the composite chemical and bacteriological data upon which it was based, and related well to known sources of pollution. Tables are presented that relate the biotic index to water quality.
