Water Quality Monitoring
1. Spatially intensive water quality monitoring was conducted monthly
(April – October) throughout the South River in 2004, 2005 and 2006 utilizing recently
developed DATAFLOW systems. Five environmental parameters (water
temperature, salinity, dissolved oxygen, turbidity, and fluorescence (used to
estimate chlorophyll a) were collected from a flow-through stream of water
collected near the surface of the water column.
2. Temporally intensive habitat assessments were conducted to compliment
the monthly water quality mapping.
Continuous monitors (YSI 6600 EDS) were located upstream and downstream of the
oyster reef in Harness Creek from April through October. Each continuous monitor
recorded water depth, water temperature, salinity, dissolved oxygen
concentrations, turbidity, fluorescence (used to estimate chlorophyll a) and pH,
and reduction potential every 15 minutes and all data was downloaded weekly.
Analysis of the continuous water quality data indicates that the oyster reef is
having a beneficial affect on water quality in Harness Creek.
