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 N R
Benthic IBI Poor - 2.0 / 5.0

Physical Stream Habitat
Instream Habitat 16/20 (Optimal)
Epifaunal Substrate 13/20 (Suboptimal)
Velocity/Depth Diversity 18/20 (Optimal)
Pool Quality
Pool Extent = 60 meters 		17/20 (Optimal)
Riffle Quality
Riffle Extent = 15 meters 		16/20 (Optimal)
Shading 40 %
Embeddedness 85 %
The embeddedness, a measure of silt on the stream bottom, was 85%. This is relatively high, and may exclude some biota.
Several measures of instream habitat were considered 'Optimal' at this location.


Stream Water Quality:
pH (lab) 8.05
Alkalinity
(acid neutralizing capacity) 		2390.3 µeq/L
Dissolved organic carbon (DOC) 1.7664 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.
