SEF Re-Established

In March 2018, the DRBC adopted a resolution to re-establish the Subcommittee on Ecological Flows (SEF), a subcommittee of the Regulated Flow Advisory Committee (RFAC). The SEF will report to the RFAC, providing scientific and technical information and advice about ecological flow goals and the effect of flow management programs on habitat and ecological health.

• Sensitive species that could be impacted by regulated flows;
  
  
• Flow regimes, thermal mitigation, and flow change mitigation;
  
  
• The effects of existing and proposed regulated flows on habitat and ecological health; and
  
  
• Such other, related matters as the RFAC may deem necessary or appropriate.
