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 Fair - 3.0 / 5.0
Benthic IBI Good - 4.7 / 5.0

Physical Stream Habitat
Instream Habitat 16/20 (Optimal)
Epifaunal Substrate 15/20 (Suboptimal)
Velocity/Depth Diversity 17/20 (Optimal)
Pool Quality
Pool Extent = 65 meters 		16/20 (Optimal)
Riffle Quality
Riffle Extent = 20 meters 		16/20 (Optimal)
Shading 90 %
Embeddedness 95 %
The embeddedness, a measure of silt on the stream bottom, was 95%. This is relatively high, and may exclude some biota.
Several measures of instream habitat were considered 'Optimal' at this location.


Stream Water Quality:
Water temperature 20.3 ° C
Dissolved oxygen (DO) 6.8 mg/L
pH (lab) 6.89
Conductivity 150 µmho/cm
Alkalinity
(acid neutralizing capacity) 		641.5 µeq/L
Dissolved organic carbon (DOC) 26.7 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.
