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 N R
Benthic IBI Poor - 1.6 / 5.0

Stream Water Quality:
Water temperature 20.3 ° C
Dissolved oxygen (DO) 1.4 mg/L
Dissolved oxygen levels measured in the stream were very low (1.4 mg/L). Many fishes and other aquatic animals cannot tolerate low levels of oxygen in the water.
pH (lab) 5.69
Conductivity 130 µmho/cm
Alkalinity
(acid neutralizing capacity) 		56.3 µeq/L
Dissolved organic carbon (DOC) 4.7 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.
