Publication Summary

As part of the Green River and Newaukum Creek Temperature and Dissolved Oxygen Total Maximum Daily Load Study, the Washington State Department of Ecology, King County Department of Natural Resources, Muckleshoot Indian Tribe, and others conducted a series of short-term water quality studies from June through September 2006. This report presents data collected during these studies. The quality assurance and quality control analysis of the data is also provided. Ecology will use the data to conduct a detailed scientific analysis and to recommend pollutant loading limits for the Green/Newaukum system.

As part of the Green River and Newaukum Creek Temperature and Dissolved Oxygen Total Maximum Daily Load Study, the Washington State Department of Ecology (Ecology), King County Department of Natural Resources, Muckleshoot Indian Tribe, and others participated in a cooperative effort to conduct a series of short-term water quality studies from June through September 2006. This report presents data collected during these studies, including field and laboratory water quality data and flow data. The quality assurance and quality control analysis of the data is also provided.

Ecology will use the data to conduct a detailed scientific analysis and to recommend pollutant loading limits for the Green/Newaukum system.

Field data include pH, conductivity, dissolved oxygen, temperature, relative humidity, flow, periphyton biomass, and riparian shade. Laboratory data include total nitrogen, total phosphorus, dissolved nutrients (nitrate+nitrite, ammonia, nitrogen, orthophosphorus), chlorophyll a, total organic carbon, dissolved organic carbon, and alkalinity.

Subsequent reports will summarize (1) how these data are used to develop predictive temperature and dissolved oxygen models, and (2) how the models are applied to establish pollutant load reduction targets for the Green/Newaukum system.
