The Commonwealth Environmental Water Office (CEWO) Long Term Intervention Monitoring (LTIM) project seeks to evaluate the outcomes of the management of Commonwealth environmental water and its contribution to Basin Plan objectives. The evaluation process is one step in the adaptive management of Commonwealth environmental water designed to support both the CEWO reporting and adaptive management obligations. This LTIM program represents a collaboration between 6 Government Departments, researchers from 6 Universities, consultants and natural resource management agencies. Commonwealth environmental water is allocated to specific high value assets to achieve specified outcomes. A core component of the evaluation is to determine the significance of these short-term areas scale outcomes in terms of progress toward achieving Basin scale objectives and targets. This presentation will describe the framework that has been developed to support this component of the evaluation and the outcomes of the first year of the evaluation of monitoring undertaken in 2014-15. A key consideration within the evaluation is that area scale outcomes are only expected to become apparent over the medium to long term as environmental flows initiate changes that take time to manifest at the larger scale. An example of this would be fish breeding where subsequent recruitment and dispersal would be expected to take time. The framework described provides a basis for considering the significance of changes in condition at the Basin scale, however, further work will be required to inform judgements for the different indicators included in the LTIM project
