This project examined the relationship of E. coli concentrations and recreational use to both stream order and watershed size. To determine possible ecoregion effects, the E. coli data used in this study were obtained from monitoring stations located on freshwater streams located in three ecoregions in Texas and Oklahoma – the Central Great Plains, Central Oklahoma/Texas Plains and South Central Plains (Ecoregions 27, 29, and 35, respectively).
