Chum • Conditions have been poor for conducting redd count surveys, so no data are available to
assess the impact of tailwater elevation. • FPAC members agree to recommend a minimum tailwater elevation of 13ʹ with a daily
rewetting elevation minimum of 16ʹ for at least four hours. • Margaret Filardo (FPC) recommended that FPAC keep up to date regarding flows and
tailwater elevations in excess of the minimums that require drafting reservoirs in order to avoid insufficient flows in February and March.
Coordination
• There will be a short FPAC call Tuesday, December 21, to discuss Chum tailwater elevation. There will be no FPAC meeting during the last week of December.
• There will be an FPOM meeting Thursday, followed by a discussion of the condition monitoring subgroup.
FPAC Agenda for Tuesday December 15, 2015 Meeting time: 9:00 AM
1. Approval of notes from November 10, November 17, and December 1 meetings 2. Water supply and reservoir status 3. Weather update and climate forecast 4. Chum operations for spawning and incubation 5. Other 6. Coordination for other schedule meetings
