Macroinvertebrates, Watershed Imperviousness, And A Water Quality Index: A Confluence Of Georgia Adopt-A-Stream’S Volunteer Data, Christopher H. Kodani
Macroinvertebrates, Watershed Imperviousness, And A Water Quality Index: A Confluence Of Georgia Adopt-A-Stream’S Volunteer Data, Christopher H. Kodani
Georgia Journal of Science
The relationship between a stream’s macroinvertebrate community as quantified by Georgia Adopt-A-Stream’s Water Quality Index and the impervious surface of an adopted stream’s watershed was weak. Although the average WQI decreased with increasing watershed imperviousness, the R2 was only 8.3%--an admittedly poor fit. To further investigate, a more comprehensive analysis was performed using forward stepwise regression. This model, which included both imperviousness and the abundance of just 15 out of the 20 kinds of macroinvertebrates, achieved an R2 of 59.4%. Imperviousness alone may not be a good predictor of WQI, but a combination of selected macroinvertebrate data and …
Impervious Surface And Macroinvertebrates In The South Atlanta Metropolitan Area, Christopher H. Kodani
Impervious Surface And Macroinvertebrates In The South Atlanta Metropolitan Area, Christopher H. Kodani
Georgia Journal of Science
Studies utilizing volunteer stream monitoring data are rare, particularly in in the Atlanta metropolitan area. This study investigated how the macroinvertebrate communities of 20 different stream sites in the south metropolitan Atlanta area were affected by the imperviousness of their surrounding watersheds. These sites were in a diverse landscape which included forests, wetlands, suburban day-use parks, and parking lots. Percentage impervious surface area was measured using Geographical Information System (GIS) analysis. Macroinvertebrates were collected using Georgia Adopt-A-Stream’s volunteer monitoring protocols, and a water quality index (WQI) was calculated from these data. The relationship between WQI and imperviousness was curvilinear and …
Assessing Small Streams In The Upper Ocmulgee Watershed Using The Georgia Adopt-A-Stream Macroinvertebrate Monitoring Protocols, Anne Stahley, Christopher H. Kodani
Assessing Small Streams In The Upper Ocmulgee Watershed Using The Georgia Adopt-A-Stream Macroinvertebrate Monitoring Protocols, Anne Stahley, Christopher H. Kodani
Georgia Journal of Science
Using Georgia Adopt-A-Stream’s (AAS) volunteer macroinvertebrate monitoring protocol, we examined how several streams’ macroinvertebrate communities differed with the land usage surrounding each stream reach. Our study sites included various headwater streams and larger tributaries of the South River within the upper Ocmulgee watershed. We sampled at different locations from January 2007 through June 2007 in a parking lot, in a wetland, several forests, and suburban parks within Clayton, Henry, and Rockdale counties, including Panther Creek, Big Cotton Indian Creek, Bush Creek, Martin Creek, and an unnamed tributary of Alexander’s Lake at Panola Mountain State Park. Sites in parking lots …
