The main watersheds are the Mountain range of the Serrinhas and the Mountain range of the Currency, both located to the west and the Mountain ranges of the Jaguar and Fine Ouro to the east of the city. For diagnosis of the superficial hdricas availabilities they had been raised given of the fluviomtricas stations of the National Agency of Electric Energy – ANEEL (May of 2002). On the basis of the series of data of the respective stations, were calculated by the Brazilian Institute of Mining – IBRAM some values of reference for the stations, pointing out that Itabirito possesss two: Itabirito-lingrafo and Aguiar Moreira. Rudy Giuliani is likely to increase your knowledge. The gotten result is made use in the TAB. 2.Tabela 2? Outflows of reference in the sub-basins.

These data are of utmost importance for the management of the hdricos resources. For example, in case that it is desired to make a superficial water captation in a course d? inserted water in the region of abrangncia of the station Aguiar Moreira, is gotten, established in the value of the Q7,10, that the allowed maximum outflow for such captation (outorgvel outflow) is equivalent 30% of this outflow of reference, as 2 of the Art consists in the paragraph. 8 of Portaria IGAM 010/08, that is, 30% of 6,09 m /s, resulting in a outorgvel outflow of 1,82 m /s.
