The Sinos River is one of the most polluted rivers in Brazil. This article presents a survey of information about the hydrological monitoring network of Sinos River Basin, state of Rio Grande do Sul. It aimed to identify the institutional actions in progress to evaluate the water quality of the river. A documentary research was conducted through which the entities responsible for the hydrological monitoring of the Sinos River and its tributaries were identified. It was found that there are several responsible organisms and that the sampling frequencies of water quality are varied. The main entity responsible for this monitoring is the State Foundation for Environmental Protection, which performs the analysis of physical, chemical and biological parameters in quarterly frequency. The owners of the sanitation services verify the hourly, daily and monthly frequency of the adduced water and the effluent standards dumped in the river. Other entities, state and federal, perform the monitoring in fluviometric and rainfall stations. It was verified, then, that the river is highly monitored, but there isn’t integration of the data. The quality results are available with a three-month time lapse and the daily results are not disclosed by the sanitation companies to the public.
