Scioto Bokes Watershed

This study investigates the effects of agriculture on the Qualitative Habitat Evaluation Index (QHEI) and the Index of Biotic Integrity (IBI) in the Scioto Bokes Watershed. The research identifies key hypotheses, such as the negative impact of agricultural practices on watershed quality and how substrate health influences IBI and ICI scores. Our findings demonstrate a correlation between dissolved oxygen levels and aquatic health, while recommending actions like resuming cleanup initiatives and managing urbanization to enhance watershed quality.

  4. Hypothesis 1: When there are large amounts of agriculture, the QHEI of a watershed decreases.

  5. Conclusion: Agriculture lowers QHEI scores because: • Riparian zone reduced • Siltation

  6. Hypothesis 2: Increasing the quality of the substrate will increase IBI and ICI.

  7. Conclusion: • ICI depends on the substrate • IBI depends on ICI • If substrate is unhealthy, the ICI and IBI are affected

  8. Hypothesis 3: As dissolved oxygen increases in the Scioto Bokes, the IBI and ICI increase.

  9. Conclusion: As the dissolved oxygen increases, the IBI and ICI also increase. There is an exception, where IBI and ICI appear to be affected by modification of the habitat (dams).

  10. Recommendations: • Restart the cleanup process of Baker Wood • Control urbanization along streams • Develop cost share program
