Index of Biotic Integrity (IBI) Results:

An Index of Biotic Integrity (IBI) is a scientific tool used to identify and classify stream health. An IBI associates anthropogenic influences on a stream or with biological condition in the stream, and is formulated using data developed from biosurveys.
Details on the development and application of MBSS IBIs are in this document.
Fish IBI Poor - 1.7 / 5.0
Benthic IBI Poor - 2.7 / 5.0

Physical Stream Habitat
Instream Habitat 6/20 (Marginal)
Epifaunal Substrate 2/20 (Poor)
Velocity/Depth Diversity 6/20 (Marginal)
Pool Quality
Pool Extent = 58 meters 		11/20 (Suboptimal)
Riffle Quality
Riffle Extent = 0 meters 		0/20 (Poor)
Shading 35 %
Embeddedness 100 %
The embeddedness, a measure of silt on the stream bottom, was 100%. This is very high, and may adversely affect biotic communities.

Dissolved organic carbon (DOC) 35.801 mg/L

Biological Stream Condition:

Surveys of the organisms living within a stream can give indications of stream health. Species richness, or the number of different species present, as well as indicator species (species whose presence, absence or abundance can serve as a measure of environmental conditions) are informative for stream health.
