DWR and scientists propose life‑cycle model focused on longfin smelt to set long‑term flow protections
Summary
DWR and partner scientists proposed building a longfin smelt life‑cycle model and related monitoring program to inform long‑term flow protection, saying the life‑cycle model could be completed within roughly three years.
At the Jan. 23 workshop Department of Water Resources (DWR) and cooperating scientists described an approach that pairs new monitoring and a longfin smelt life‑cycle model with the Healthy Rivers & Landscapes (HRL) commitments and the State Water Project incidental take science program to develop a longer‑term base‑flow protection criterion.
Why it matters: DWR and CDFW presenters emphasized that a multi‑driver life‑cycle model (flow, temperature, food, habitat, entrainment and adult stock) can integrate complex drivers to generate a more defensible long‑term flow objective than a single threshold. DWR stated that the model will be part of the HRL science program and could be used to propose base‑flow protections for later…
