溶解氧（DO）的测量从格鲁吉亚自然资源部，环境保护司和美国地质调查局水质采样程序从1966年至2001年进行了分析，使用谐波曲线拟合程序。统计数据从31个站，选择代表大部分自然流DO和温度条件，被用来计算全州流DO模型，其主要变量包括纬度和海拔。基于1966-2001年的参考期，该模型可用于计算长期的，季节性特征的溶解氧在格鲁吉亚流。使用相同的31个站点，第二个模型来计算长期的季节性特征的溶解氧在格鲁吉亚流推导出流温度的谐波特性。该模型定量链接长期流温度长期流DO作为因果关系。
Dissolved-oxygen (DO) measurements from the Georgia Department of Natural Resources, Environmental Protection Division and the U.S. Geological Survey water-quality sampling program from 1966 to 2001 were analyzed using a harmonic curve-fitting procedure. Statistics for data from 31 stations, selected as representing mostly natural stream DO and temperature conditions, were used to compute a statewide stream DO model whose principal variables include latitude and elevation. Based on the 1966–2001 reference period, the model may be used to compute long-term, seasonal characteristics of DO in Georgia streams. Using the same 31 stations, a second model to compute long-term seasonal characteristics of DO in Georgia streams was derived using harmonic characteristics of stream temperatures. The model quantitatively links longterm stream temperatures to long-term stream DO as a cause-and-effect relation.
