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.

|
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) |
7.12 |
Alkalinity
(acid neutralizing capacity)
|
435.5 µeq/L |
| Dissolved organic carbon (DOC) |
5.2506 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.
