Continuous Water Quality Monitoring at Lake Mattamuskeet (pdf 189Kb).
The U.S. Fish and Wildlife Service has partnered with the U.S. Geological Survey to establish two automated water-quality monitoring stations at Lake Mattamuskeet to better understand the lake’s ecology. Managers are concerned that submerged macrophyte populations have declined on the west side of the lake and we are helping determine the extent to which the decline may be due to poor water quality.
The Service’s Environmental Contaminants Program collects and interprets data to help the public, regulators, and other decision makers. With the removal of Milburnie Dam under consideration, we coordinated an investigation of sediment pollution as technical assistance to interested stakeholders. Our final report demonstrates that concentrations of heavy metals and hydrocarbons in sediments upstream of the dam are less than levels of concern. We also documented that the highest sediment pollutant concentrations were typically from downstream of the dam.
