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 - 4.0 / 5.0
Benthic IBI Fair - 3.3 / 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 658 acres A highly channelized urban stream with concrete banks. An example of a highly channelized urban stream.
Urban Land Use 21.5 %

Physical Stream Habitat
Instream Habitat 14/20 (Suboptimal)
Epifaunal Substrate 16/20 (Optimal)
Velocity/Depth Diversity 10/20 (Marginal)
Pool Quality
Pool Extent = 58 meters 		9/20 (Marginal)
Riffle Quality
Riffle Extent = 17 meters 		12/20 (Suboptimal)
Shading 65 %
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) 6.73
Alkalinity
(acid neutralizing capacity) 		174.7 µeq/L
Dissolved organic carbon (DOC) 2.1358 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.
