The goal of this project was to develop methodologies to validate environmental flows adopted by the State. This was accomplished by first conducting a workshop with an expert panel to develop several theories on how certain chemical and physical parameters as well as biological indicators will respond to the various tiered flow recommendations. These indicators were identified by the expert panel. Then the selected indicators were studied at several sites and under several flow regimes to validate the theories and the associated flow recommendations. This information can then be used to refine future environmental flow recommendations.
