BROWN BAG SEMINAR: Development of Recommended Flow Targets to Support Biological Integrity Based on Regional Flow-Ecology Relationships for Benthic Macroinvertebrates in Southern California Streams

Dr. Eric Stein is the principal scientist at Southern California Coastal Water Research Project where he oversees a variety of different kinds of projects focused on instream and coastal water quality, bioassessment, hydromodification, watershed modeling, and assessment of wetlands and other aquatic resources. This brown bag seminar is the second of three seminars focused on flow targets and ecology (part […]

BROWN BAG SEMINAR: Developing Tiered Environmental Flow Criteria Using a Functional Flows Approach for California Streams

Establishing environmental flow targets to protect aquatic communities is a priority for numerous programs in California including in the Delta. In this first of three brown bag seminars focusing on flow targets and ecology, Dr. Yarnell discusses her recent work using a functional-flows approach to develop statewide environmental flow recommendations. The approach allows for the rapid development of flow regimes […]

DR. BRUCE HERBOLD: Delta Flows and the effects of water transfers

Dr. Bruce Herbold is a retired EPA fish biologist and now a consultant on the same issues.  In this presentation from the AquAlliance conference last fall, Dr. Herbold discusses drought, flows in the Delta, and the effects of transfers on the fish in the Delta. Dr. Herbold began by saying that managing water in California is fraught with difficulties, and […]

Utilizing Bioassessments and Citizen Science for Stewardship in the Truckee River Watershed

The Adopt a Stream program of the Truckee River Watershed Council has grown from a one-day monitoring event to quarterly monitoring and a robust bioassessment program. Approximately 100 volunteers participate in the monitoring program annually. Volunteers monitor key tributaries and a handful of sites along the Truckee River. TRWC uses the data to identify sites for restoration and stormwater improvements […]
