(Group #1)
Assignment To develop a few hypothesis about
the Fourmile watershed, in order to demonstrate our knowledge of Watersheds and water quality issues
Methodology
Day 1- Chemical Test Water Samples, Watershed Lecture

Methodology 2
Definition Page 1IBI = Index biotic integrityICI = Invertebrate community indexQHEI = Qualitative habitat evaluation index DO = Dissolved OxygenTSS = Total Suspended SolidsStation ID = Number representing where the tests were done
Point Source Pollution = A known source of pollutionNon Point Source Pollution = An unknown but suspected source of pollutionRiparian Zone = A type of habitat associated with lush vegetationMeander = a natural curve or turn in a creek or river bedBOD = Biochemical Oxygen Demand

Hypothesis
H1: When the QHEI (Qualitative Habitat Evaluation Index) increases, the ICI (Invertebrate Community Index) and the IBI (Index of Biotic Integrity) increase
H2: The closer the creek is to the city the lower the ICI and the IBI
H3: The TSS (Total Suspended Solids) increases in agricultural areas

Hypothesis #3
Results H1:The hypothesis is correct. When the QHEI
increased the ICI and IBI increased. H2: The hypothesis is correct. Due to the location
of an urban setting the ICI and IBI levels decrease near the city and increase near the rural areas.
H3: The hypothesis is correct. This hypothesis was also based on location and the TSS level was higher if it was near a rural area, rather than an urban area.

Conclusion We tested our hypotheses and we
concluded that, according to our research, our hypotheses were all correct.
All of our graphs based on our research showed that we came up with the correct hypotheses about our watershed.
