Researchers studied water quality at 4 sites along the Shell Creek watershed in May 2003. Water quality tests were performed and water quality indices (WQI) were calculated for each site. WQI scores ranged from 56.93 to 61.33, indicating medium water quality. Higher turbidity, fecal coliform, and biochemical oxygen demand (BOD) were observed at some sites.

2003 Shell Creek Watershed Study Researchers: Amanda Gasper, Melissa Gasper, Anjuli Mostek, Katie Stone, Katie Dunlap, Courtney Bennett, Brittany Pieke, Sarah O’Brien, Instructor: Mark Seier
Introduction •Site 1- Instead of testing on Paul Cederland’s property, we moved to a site on Tim Krueger’s farm. This enabled us to have a sight on the South branch • Site 2- This is the site with established buffer zones. It is on the North branch. Here we have roadside access to the site. • Site 3- Located on Brad Wallin’s land. At this point, the north and south branches have already converged. • Site 4- Just below Newman Grove on Katie Hallgren’s property. Scoured banks are trademark to this site. It also lies below the waste water treatment facility.

WQI • The Water Quality Index was developed by the National Sanitation Foundation as a standard system to compare different bodies of water. • To determine the WQI, a series of nine tests were performed. These tests were: dissolved oxygen, fecal coliform, pH, Biochemical Oxygen Demand (BOD), temperature, total phosphate, nitrates, turbidity, and total solids. We also did a water discharge test which we use to measure the flow of the creek in cubic feet per second.
• After the tests are completed, the WQI for each section of the creek can be computed. To formulate the WQI, we first computed Q-values which is a number determined from a weighting curve chart. We multiply this number by a weighting factor, which provides a measure of the relative importance of each test to overall water quality. The water quality index ranges from zero to 100. Zero to 25 is very bad. 25 to 50 is bad. 50 to 70 is medium. 70 to 90 is good, and 90 to 100 is excellent.

NG Shell Creek Data Powerpoint 2003

  • 1. 2003 Shell Creek Watershed Study Researchers: Amanda Gasper, Melissa Gasper, Anjuli Mostek, Katie Stone, Katie Dunlap, Courtney Bennett, Brittany Pieke, Sarah O’Brien, Instructor: Mark Seier
  • 2. Introduction •Site 1- Instead of testing on Paul Cederland’s property, we moved to a site on Tim Krueger’s farm. This enabled us to have a sight on the South branch • Site 2- This is the site with established buffer zones. It is on the North branch. Here we have roadside access to the site. • Site 3- Located on Brad Wallin’s land. At this point, the north and south branches have already converged. • Site 4- Just below Newman Grove on Katie Hallgren’s property. Scoured banks are trademark to this site. It also lies below the waste water treatment facility.
  • 4. WQI • The Water Quality Index was developed by the National Sanitation Foundation as a standard system to compare different bodies of water. • To determine the WQI, a series of nine tests were performed. These tests were: dissolved oxygen, fecal coliform, pH, Biochemical Oxygen Demand (BOD), temperature, total phosphate, nitrates, turbidity, and total solids. We also did a water discharge test which we use to measure the flow of the creek in cubic feet per second.
  • 5. • After the tests are completed, the WQI for each section of the creek can be computed. To formulate the WQI, we first computed Q-values which is a number determined from a weighting curve chart. We multiply this number by a weighting factor, which provides a measure of the relative importance of each test to overall water quality. The water quality index ranges from zero to 100. Zero to 25 is very bad. 25 to 50 is bad. 50 to 70 is medium. 70 to 90 is good, and 90 to 100 is excellent.
