Erika Stroebel, senior planner for Marine Resources, and Atina Casas from the Marine Resources committee of Whatcom County Public Works, plowed through tall grasses and muddy banks on their bi-monthly gathering of samples to test the quality of water sources draining into Birch Bay on Thursday, July 19.
Water testing is ideally always done at low tide. Because Terrell Creek drains into Birch Bay, at every point the salinity of the water needs to be tested to see the effect the tide may have on the samples, Stroebel said.
Samples were taken at eight different locations along Terrell Creek in Birch Bay. Some locations were untestable due to the low tide and the low water flow in the sampling areas.
In the past other groups such as Nooksack Salmon Enhancement Association and the Whatcom Conservation District have also done sampling, Stroebel said. Other coastal drainages throughout the county are monitored as well.
