At each site, physical, biological, and chemical observations were examined. Physical observations include date, time, location, GPS reading, latitude, longitude and map location. Complete weather observations include air temperature, barometric reading, wind, cloud cover description and rainfall narrative. Streamside observations include land use, slope, plant growth, riparian zone description and narrative describing the stream. The temperature was measured with an analog thermometer. Observations were noted on the physical characteristics including sketches and stream flow of each site. Chemical characteristics were measured with a Vernier LabPro analyzer. The Vernier was calibrated for dissolved oxygen and pH in the lab before leaving for our site. Dissolved oxygen and pH were then tested in the field. Samples were collected from each site, stored in a cooler on ice and tested upon returning to the lab. Three measurements were taken for pH, turbidity, dissolved oxygen, nitrates, conductivity and flow using the Vernier. Three phosphate samples were collected and returned to the lab for testing. Samples were collected for the retention ponds by dipping a 5-gallon bucket into the pond. Samples were collected and labeled. Back in the lab, spectrophotometers were set with standards of 0, .05, .10 and .50 mg P/L. To examine biological characteristics, macroinvertebrate samples were collected.
