BROWN BAG SEMINAR: California floodplains and the fish that use them

Science Features

How restoring functional flows to floodplains could help restore native fish Two centuries ago, the floor of the Central Valley was largely a marshy wetland.  In the springtime, the snowpack would melt, swelling the rivers beyond their banks and casting the young fish out onto the floodplains.  There they would stay for months, fattening up on the abundant zooplankton and […]

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

News and Features, Science Features

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 […]
