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 Poor - 2.7 / 5.0
Benthic IBI Poor - 2.7 / 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 346 acres A highly channelized urban stream with concrete banks. An example of a highly channelized urban stream.
Urban Land Use 57.6 %
Agricultural Land Use 22.3 %
Forested Land Use 19.8 %

Physical Stream Habitat

Instream Habitat 7/20 (Marginal)
Epifaunal Substrate 4/20 (Poor)
Velocity/Depth Diversity 6/20 (Marginal)
Pool Quality
Pool Extent = 65 meters
11/20 (Suboptimal)
Riffle Quality
Riffle Extent = 10 meters
1/20 (Poor)
Shading 70 %
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:

Water temperature 19.8 ° C
Dissolved oxygen (DO) 3.8 mg/L
Dissolved oxygen levels measured in the stream were very low (3.8 mg/L). Many fishes and other aquatic animals cannot tolerate low levels of oxygen in the water.
pH (lab) 7.67
Conductivity 599 µmho/cm
Alkalinity
(acid neutralizing capacity)
1780.6 µeq/L
Dissolved organic carbon (DOC) 7.7052 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.
