Collecting Data
Streamflow and water quality measurements were made at the 17 sites in the Floyds Fork
basin starting at the Oldham-Jefferson county line and extending to Bullitt County near
the Floyds Fork mouth. These measurements were taken during relatively low-flow
conditions from July 24 to July 27, 1991. Measurements were also made near the mouth
of other tributaries. They were taken during hot weather conditions because a stream
is most stressed during warm and hot temperatures. No major rainfall occurred for
the two weeks before or during the
tests.
Measurements for dissolved oxygen, water temperature, specific conductance, and pH were made using a Hydrolab model 4041 portable
water quality meter. Quality control measurements of dissolved oxygen using the
Winkler Titration method were done at the first site each morning and throughout the day
to guarantee accuracy. Dissolved oxygen and water temperature were also measured
hourly during the day for periods from 21 to 25 hours at six locations in Floyds Fork
using two Hydrolab automatic Datasonde I units. The locations were Floyds Fork at:
Highway 362
Floyds Fork at Fisherville
Floyds Fork at Seatonville Road
Floyds Fork at Bardstown Road
Floyds Fork at Highway 1526
Floyds Fork at mile 2.5 behind a subdivision off Highway 44.
Dissolved oxygen
measurements were made when setting and removing the Datasonde I units (a water testing
procedure) to get accurate data. This data was later compared with the field
measurements.
