WCU 2019 Annual Lake Glenville Water Quality Report

The Annual Report covering 2019 for stream testing of tributaries feeding into Lake Glenville has been released. Within this report there is more robust analysis with charting and comparisons back to 2007. There is also a comparison of the past 3 years' results that have occurred under this agreement with WCU. Click through to read the full report and learn some of the key takeaways, which include:

 

  • Although orthophosphate is only one component of total phosphorous, observed concentrations at Glenville, Pine, Mill, and Norton Creeks exceed the EPA nutrient criteria for total phosphorous. However, allstreams continue to exhibit significantly decreased orthophosphate concentrations in Year 3 compared to Years 1 and 2
  • The ambient standard (for nitrates) to protect aquatic ecosystems is 10mg/L and observed concentrations at all monitored sites are well below this ambient standard (Figure 31). However, the EPA nutrient criterion for total nitrogen in rivers and streams in this ecoregion is 0.31 mg/L. Although nitrate is only one component of total nitrogen, observed concentrations in all streams exceeded this EPA nutrient criterion for total nitrogen, thus making it more susceptible to eutrophication.
  • All streams except Glenville Creek demonstrated increases in E. coli concentrations from Year 2 to Year 3 of this study. Except for Pine Creek, these increases are below the recreational E. coli standard and may be the result of increased precipitation and runoff events
