North Delta Diversion Bypass Flows @
Objectives: Maintain adequate river fl ows to (1)
keep fi sh away from the pumps, (2) keep fi sh moving
in the right direction, towards regions of suitable
habitat, (3) minimize fi sh predation, (4) maintain or
improve the overall quality of rearing habitat in the
north Delta.
Delta Cross Channel Gate
Operations
Objectives: (1) reduce movement of
outmigrating Sacramento River fi sh into
central Delta, (2) maintain fl ows downstream
on Sacramento River, and (3) provide enough
Sacramento River fl ow into interior Delta when
water quality for municipal and industrial use
and agriculture may be of concern.
Rio Vista Flows
Objectives: maintain fl ows for
migrating salmon and smelt.
Yolo Bypass
Objectives: (1) modify Fremont or
Sacramento weirs to increase the
frequency and duration of Yolo Bypass
inundation, (2) increase spawning
and rearing habitat for splittail
and salmon, (3) provide alternate
migration corridor to the mainstem
Sacramento River, and (4) increase
availability and quality of food and
habitat in Cache Slough.
South Delta Channel Flows @
Objectives: (1) improve fi sh survival by reducing the risk of their capture at the south
Delta pumps, (2) increase survival of juvenile salmon and steelhead by keeping them on
their migration path, (3) improve downstream transport of larval and juvenile fi sh, and
(4) improve the production of food resources within the Delta and Suisun Bay.
@ Primary factor in managing Delta Flows
Outfl ow @
Objectives: (1) Provide enough outfl ow to maintain acceptable
salinity levels during the spring, and (2) explore variable infl ow
and outfl ow criteria to make water conditions more suitable for
fi sh (e.g. better mimicking of natural seasonal fl ows).
In-Delta Water Quality
Maintain existing water quality standards in the
North, Central, and West Delta.
Infl ow
Potential objectives: (1) maintain
seasonal and daily increases and
decreases in river fl ows between the
mainstem Sacramento River and its
tributaries, (2) maintain environmental
cues used by fi sh and other aquatic
species to signal spawning, migration,
and other population responses and
behaviors, and (3) increase the survival
and growth of covered fi sh inhabiting
the river and estuary.
Tidal marsh restoration over and above the minimum tidal marsh
targets in each ROA, up to 65,000 acres, would be expected to occur
over the life of the plan depending in part on the availability of willing
sellers, as well as the total relative amount of suitable habitat within
each ROA, among other factors.
