Testimony at 1969-70 SWRCB Water Rights Hearings:•
“Fish and wildlife problems”
in the estuary
•
SWP & CVP may contribute Need studies to
•
Understand fish and wildlife resource requirements •
Find ways to minimize SWP & CVP impacts

Interagency EcologicalSTUDIES
Program (IESP)
1970-1982:
Focused studies to allow “full”
water project development (with Peripheral Canal)
1982-90s:
Monitoring and studies to meet regulatory requirements & evaluate effects of project operations, fish facilities, barriers
1993:
Program review –
reorganization, IEP2000s:
Pelagic Organism Decline (POD) study
focus
Future?
Integrated Environmental Assessments (Socio- Ecological Science) –
System shifts, B.O.s, BDCP (P.C.!)
1970 MOA
