| Description | Prevalent surface water quality problems in Portage Creek are probably exacerbated by land use in the watershed and by ground water influences. Quantified land use and activity information for the Portage Creek watershed was useful in interpretation of patterns of pollution observed during this study. Land use types such as pasturing and cropland appeared to significantly influence water quality in Portage Creek. Total suspended solids and total inorganic nitrogen concentrations and loads were probably influenced by over-application of manure or commercial fertilizers during the wet season. Total phosphorus and fecal coliform concentrations were not found to be seasonally influenced. | ||||
