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 Good - 4.7 / 5.0
Benthic IBI Good - 4.1 / 5.0

Land Use

Land use can provide important information for determining stream health.
(Hint: Screen readers will announce definitions; mouse users can hover over dotted text.)

Physical Stream Habitat

Instream Habitat 15/20 (Suboptimal)
Epifaunal Substrate 14/20 (Suboptimal)
Velocity/Depth Diversity 10/20 (Marginal)
Pool Quality
Pool Extent = 47 meters
10/20 (Marginal)
Riffle Quality
Riffle Extent = 28 meters
13/20 (Suboptimal)
Shading 80 %
Embeddedness 100 %
The embeddedness, a measure of silt on the stream bottom, was 100%. This is very high, and may adversely affect biotic communities.


Stream Water Quality:

pH (lab) 6.55
Alkalinity
(acid neutralizing capacity)
333.2 µeq/L
Dissolved organic carbon (DOC) 12.955 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.
