The Negro River Estuary is a micro to meso tidal influenced estuarine system in a semi arid region in North Patagonia Argentina. The status of its quality waters has raised interest in the last years by increased uses,urban, agriculture, fishing and nautical sports of international levels. Waters samples were taken from spring 2011 to autumn 2013 to determine microbiological transport among Guardia Mitre and Atlantic Ocean zone. Total coliform, fecal and E. coli were examined by NMP per 100 ml in relation to environmental parameters and point sources. The Pearson correlation was typically significant with temperature, and preliminaries results revealed E. coli survived in winter months at low temperatures (maximum level of 93 NMP/100 ml) and had negative correlations with other anthropic and environmental parameters.
