Portugal recently faced a severe financial crisis that led to a suspension of funding to water monitoring programmes of the Water Information System (WIS), SNIRH. This caused a severe impact as WIS and shared databases are considered key mechanisms for sharing water basin, country and international policy. This study provides the first empirical assessment of SNIRH performance, in the context of groundwater governance, in order to verify whether the WIS complies with the fundamentals of Principle 5 of OECD Principles on Water Governance. The methodology adopted is based in a refinement of the updated DeLone and McLean Information System Success towards the assessment of a web-based water information system performance in the context of groundwater governance. The model consists of five dimensions: Information Quality, System Quality, System Use, User Satisfaction and Perceived Net Benefits. The analysis and quantification of relationships among the model data collected by questionnaire from 111 users was made through the application of structural equations modelling and multiple correspondence analysis. The proposed model proved to produce good reliability estimates thus demonstrated that the measurement model exhibited a good fit with the data collected. The findings of this research provide important input and implications for the water information systems and for groundwater governance in particular. The paper concludes with a discussion on the limitations and governance areas of improvement that could be addressed in future developments.
