River Woods Start

  1. 1. River Woods Stream Study
  2. 2. Park Rules <ul><li>Which river is flowing through River Woods Park? </li></ul>
  3. 3. Where does the Clinton River empty into?
  4. 4. <ul><li>A Watershed </li></ul><ul><li>Definition </li></ul><ul><li>The total land area that contributes water (or drains into) a particular waterway. </li></ul><ul><li>Can also be called a </li></ul><ul><li>“ Drainage Basin” </li></ul>
  5. 5. Is the Clinton River becoming cleaner? <ul><li>In the late 1960s the water resources commission deemed the Clinton River the “foulest river in Michigan.” </li></ul><ul><li>Today the water quality is improving. </li></ul><ul><li>The 80 miles of the main branch are considered generally swimmable and fishable. </li></ul>
  6. 6. Where should we start our study?
  7. 7. You will be assigned to a group either: Physical and Macro <ul><li>Physical Survey is an inventory of the surrounding area </li></ul><ul><li>Macro: </li></ul><ul><li>You will study macroinvertebrates and the stream chemical testing </li></ul>
  8. 8. SAFETY FIRST <ul><li>Lifejackets </li></ul><ul><li>Listen to the adult supervisor </li></ul><ul><li>Only enter water at macroinvertebrate site </li></ul>
  9. 9. Physical Survey
  10. 10. Physical Survey includes <ul><li>Stream Velocity </li></ul><ul><li>Weather </li></ul><ul><li>Stream Habitats </li></ul><ul><li>Stream Vegetation </li></ul><ul><li>Contaminates in the </li></ul><ul><li>area </li></ul>
  11. 11. Stream Velocity: Speed and Distance <ul><li>To test velocity we mark off a distance and time an orange as it goes down the river </li></ul>
  12. 12. Weather Conditions <ul><li>You must record weather conditions for the day </li></ul><ul><li>Precipitation </li></ul><ul><li>Air temperature </li></ul><ul><li>Water temperature </li></ul><ul><li>clouds </li></ul>
  13. 13. Record Stream Habitat <ul><li>Width </li></ul><ul><li>Depth </li></ul><ul><li>Water velocity </li></ul><ul><li>Soil type: sand/loam, clay, organic </li></ul><ul><li>Water clarity </li></ul><ul><li>Water odor </li></ul><ul><li>trash </li></ul>
  14. 14. Stream Vegetation <ul><li>Trees </li></ul><ul><li>Shrubs </li></ul><ul><li>Herbaceous plants </li></ul><ul><li>Grass </li></ul><ul><li>Bare </li></ul><ul><li>Stream Shading 100-0% </li></ul><ul><li>Bank Erosion </li></ul>

  17. 17. Aquatic Plants <ul><li>Periphyton http://www.epa.gov/bioiweb1/html/periphyton.html </li></ul><ul><li>Filamentous algae http://www.sfr.cas.psu.edu/water/filamentous%20algae.htm </li></ul><ul><li>Macrophytes http://www.epa.gov/bioindicators/html/macrophytes.html </li></ul>
  18. 18. Contaminants?
  19. 19. Riparian Vegetation
  20. 20. Macro invertebrate Study
  21. 21. Identifying pollution sensitive creatures
  22. 22. Chemical Testing <ul><li>pH </li></ul><ul><li>Turbidity </li></ul><ul><li>Dissolved Oxygen </li></ul><ul><li>Ecoli </li></ul>
  23. 23. Photos to take at each station We must record our visit and data to analyze! <ul><li>Wildlife </li></ul><ul><li>Pollutants </li></ul><ul><li>Downstream </li></ul><ul><li>Upstream </li></ul><ul><li>Collection </li></ul><ul><li>Vegetation </li></ul><ul><li>Land Use </li></ul>
