Aquatic Classification System


Aquatic Classification System :

Assigns a classification to a waterbody reflecting the water quality and the biological health (integrity). Classification is determined through use of biological indices (See: IBI). Examples of classifications include oligosaprobic (cleanest water quality) and polysaprobic (highly polluted water). IBI: The IBI uses measurements of the distribution and abundance or absence of several fish species types in each waterbody for comparison. A portion of a waterbody is compared to a similar, unimpacted waterbody in the same ecoregion. Water Quality: The biological, chemical, and physical conditions of a waterbody. It is a measure of a waterbody's ability to support beneficial uses
