Abstract	O presente trabalho estabelece o balanco hidrico mensal da bacia do rio Barigui para o periodo de 1985 a 2000, determinando para cada mes o armazenamento ativo de agua na bacia. Foi utilizado um metodo de ajuste de evapotranspiracao calculado com dados meteorologicos observados fora da bacia em analise. Para a evapotranspiracao utilizaram-se estimativas medias de longo prazo da diferenca entre precipitacao e defluvio, que foram ajustadas adotando a proporcionalidade entre armazenamento na bacia e evapotranspiracao real. A contribuicao do despejo de esgoto domestico foi estimada a partir de dados demograficos sobre a populacao residente na bacia. Os fluxos de agua subterrânea para dentro e fora da bacia foram desprezados. Os resultados obtidos foram coerentes com estudos similares realizados na mesma regiao e mostram uma precipitacao media no periodo de 1.251 mm e um defluvio medio de 751 mm com um coeficiente de escoamento medio de 0,50. Water balance of the Barigui river basin in Parana State - Brazil Abstract This paper consolidates the water balance of the Barigui River in the Metropolitan Area of Curitiba for the period of time 1985-2000, defining for each month the watershed storage. It is proposed an evapotranspiration approximation based upon meteorological data measured close to the watershed. Evapotranspiration is estimated using long term averages of the differences between precipitation and streamflow data adjusted by assuming that storage and real evapotranspiration are proportional. The sewage contribution was estimated by watershed demographic data. The results are consistent with similar studies and show an average precipitation amplitude of 1251 mm and streamflow of 751 mm over the period analyzed.
