Warm Water
Poor
CLEAR SKY, AIR TEMP. ABOUT 75 F. FLOW BARELY PERCEPTIBLE DUE TO LOW GRADIENT, PROBABLY NEAR BASE FLOW OR SLIGHTLY BELOW. WATER WAS TURBID; BOTTOM VISABLE TO ONLY APPROX. 1 FT. SAMPLING EFFECTIVENESS FAIRLY POOR DUE TO LARGE, DEEP AREAS THAT WERE INACCESSIBLE. EVEN SO, FISH ABUNDANCE WAS LOW DESPITE SAMPLING EQUIP. APPARENTLY FUNCTIONING PROPERLY. SEE FLD.NOTES

FIBI Score Explained
Sites that score between 0 - 25 are considered poor. Fish abundance is usually lower than normal or, if fish are abundant, the collection is dominated by a few tolerant species. The number of native fish species present is low. Sensitive species and habitat specialists are absent or extremely rare. The population is dominated by just a few ubiquitous species that are tolerant of wide-ranging water quality and habitat conditions. Pioneering, introduced and/or short-lived fish species are typically the most abundant types of fish. Fish collected at poor sites often have a higher than normal occurrence of external physical anomalies.
This location has been classified as a survey site. Survey sites are compared to reference sites within the same ecoregion. A reference site represents natural stream qualities that are least disturbed by human activities within the watershed. Reference sites are grouped by ecoregion to establish a benchmark against which these survey streams are compared.
