The Columbia River Inter-Tribal Fish Commission (CRITFC)
presents the 2003 River Operations Plan for the Federal Columbia River
Power System (FCRPS), the Hells Canyon Complex and mid-Columbia FERC- licensed
hydro-projects including Rock Island, Rocky Reach, Wanapum and Priest Rapids.
The plan contains recommendations for water management and dam operations,
including flows, reservoir elevations, spill, and fish facility operations.
In 2001, low runoff and financial and power emergencies declared by
BPA eliminated fish flow augmentation and reduced fish spills to a fraction
of those required under the NMFS (NOAA Fisheries) 2000 Biological Opinion
for the Federal Columbia Power System (FCRPS). Salmon and steelhead
losses
were significant. For example, the Fish Passage Center noted that only
4% of Snake River juvenile steelhead survived passage from Lower Granite
to Bonneville Dam, and some 27% of Snake River juvenile chinook survived
to Bonneville.
CRITFC staff, through independent analyses, project about a 68 million
acre-feet runoff forecast. Plan operations were modeled against probable
federal river operations. The plan uses altered flood control rule
curves and additional “pockets of water” from upper basin storage
to create a natural flow regime for virtually all major river index points.
The CRITFC plan operations assure beneficial flows for anadromous fish,
while seeking to maintain higher reservoir levels for resident fish and
tribal cultural resource protection. The plan also contains specific
recommendations and guidelines for power peaking, adult and kelt passage,
water temperature
criteria to meet Clean Water Act standards, water management during the
tribal treaty fisheries, fish facility operations and mainstem research.
The water saved from altered flood control operations could then be applied
to spring salmon migrants.
