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 - 4.4 / 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.)
Catchment area 3,812 acres A stream flowing through a densely forested area. An example of a forested stream.
Urban Land Use 8 %

Physical Stream Habitat
Instream Habitat 2/20 (Poor)
Epifaunal Substrate 3/20 (Poor)
Velocity/Depth Diversity 1/20 (Poor)
Pool Quality
Pool Extent = 8 meters 		3/20 (Poor)
Riffle Quality
Riffle Extent = 0 meters 		0/20 (Poor)
Shading 92 %
Embeddedness 100 %
The embeddedness, a measure of silt on the stream bottom, was 100%. This is very high, and may adversely affect biotic communities.
Several measures of instream habitat were considered 'Poor' at this location.


Stream Water Quality:
Water temperature 23.4 ° C
Dissolved oxygen (DO) 4.3 mg/L
Dissolved oxygen levels measured in the stream were very low (4.3 mg/L). Many fishes and other aquatic animals cannot tolerate low levels of oxygen in the water.
pH (lab) 6.95
Conductivity 160 µmho/cm
Alkalinity
(acid neutralizing capacity) 		569.7 µeq/L
Dissolved organic carbon (DOC) 3.4 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.
