Water recycling can result in a reduction of instream flow and can impact existing and future instream beneficial uses, setting up potential conflicts between policies aimed at promoting reuse, protecting water quality, and managing ecological resources. Join us to learn about the California Environmental Flows Framework, which can be used to establish seasonal flow criteria. This framework is currently being applied in the Los Angeles River watershed to better evaluate the cumulative impacts of potential flow reductions associated with several water reuse and water capture projects. The project will provide a science-based approach for assessing flow necessary to sustain beneficial uses. The project outcomes will be used to help establish technically sound flow recommendations and evaluate the consequences of alternative flow scenarios for the LA River. This project may also serve as a model for assessing similar situations in other river systems across the state.
Dr. Eric Stein is a head of the Biology Department at the Southern California Coastal Water Research Project (SCCWRP). Dr. Stein oversees a variety of projects related to in-stream and coastal water quality, bioassessment, hydromodification, watershed modeling, and assessment of wetlands and other aquatic resources. His research focuses on effects of human activities on the condition of aquatic ecosystems, and on developing tools to better assess and manage those effects.
