NG Shell Creek Data Powerpoint 2002

  1. 1. Researchers: Amanda Gasper, Anjuli Mostek, Jamie Lorenzen, KatieStone, Courtney Bennett, Mike Voelker, Aaron Hallgren, Instructor: Mark Seier
  2. 2. Mission Collect data to report to the Shell CreekWatershed Improvement Group and NebraskaWildlife Federation Learn about the geography and location of the Shell Creek and the area it involves Become knowledgeable about water chemistry parameters and their significance to the stream’s inhabitants Learn about biological stream factors and how they indicate water quality
  3. 3. ProceduresA total of four sites were selected and latitude andlongitude were determined by using Global PositioningSystem (GPS).Sampling was done in two day sets. First day was chemical testingand the second was macroinvertebrate sampling.Chemical tests run include: pH, water temperature,turbidity, conductivity, velocity, nitrates, dissolved oxygen,and oxygen saturationMacroinvertebrate sampling was done using a D-net andincluded 20, 1-foot square samples at each site.We also usedHester-Dendy samplers. Fish were sampled using a seine.
  4. 4. Water Test Natural Readings Cautionary ReadingsDissolved Oxygen 5-14 ppm Below 5: water quality violation 1.5-5: stress resulting in abnormal feeding and reproduction 1.5: mortality 0: anoxicpH 6.5 - 8.5 Below 6.5 Above 8.5Nitrates 0.0 - 1.0 ppm Consistent readings above 3 ppmTemperature Varies Above 27o CelsiusTurbidity 0 – 8 JTU Increasing trends in turbidity measurements

  20. 20. Conclusions and Concerns•Low dissolved oxygen and % saturation rates•High levels of turbidity•High amounts of silt and sediment•Low macroinvertebrate diversity•Scoured banks at site 4
  21. 21. Suggestions for future studies:• We would like to add the tests: fecal coliform, biochemical oxygen demand, total phosphates, and total solids; to calculate the overall water quality index number.• Continue to monitor same sites and add one or two new locations
  22. 22. We would like to thank the Shell Creek Watershed Improvement Group and theNatural Resource District for providing us with the testing materials. We would also like to thank the landownerswho owned the area around the sites we tested for their cooperation in this study: PaulCederlind, Fred Fehringer, and Katie Hallgren.
