This site is on public land, such as a county park, state park, or state-managed wildlife area.
Warm Water
Good
Cloudy, rain threatening. Flow level was above normal flow because of abundant rainfall this year. Turbidity level was moderate. The stream bottom was visible to approx 2.5 ft. sampling effectiveness was only fair (2) because of flow level, current velocity, and 1 deep, inaccessible spot. Did not have time to do all 10 transects for hab sampling.

FIBI Score Explained
Sites that score between 51 - 70 are considered good. Fish (excluding tolerant species) are fairly abundant to very abundant. If high numbers are present, intermediately tolerant species or tolerant species are usually dominant. A moderately high number of fish species belonging to several families are present. The three most abundant fish species typically comprise two-thirds or less of the total number of fish. Several long-lived species and benthic invertivore species are present. One or more sensitive species are usually present. Top carnivore species are usually present in low numbers and often one or more life stages are missing. Species that require silt-free, rock substrate for spawning or feeding are present in low proportion to the total number of fish. Fish condition is good; typically less than 1% of the total number of fish exhibits external anomalies associated with disease or stress.
This location has been classified as a Rejected Reference Site. This site was a Reference Site at one time, but subsequent biological assessments have determined that this site no longer meets the qualifications of a Reference Site.
