Biological Opinions for the Sacramento-San Joaquin Delta: A Case Law Summary

Summary
For decades biologists, water users, and lawmakers (both federal and state) have attempted to
craft a system that meets the needs of California water users while ensuring sufficient usable
water for fish. Under California’s hybrid system of appropriative water rights, users are issued
permits for water diverted from rivers and streams regardless of the users’ proximity to the source
of water. The state of California has issued permits to the Bureau of Reclamation (the Bureau) to
store, divert, and deliver water from the federal Central Valley Project (CVP), which consists of
facilities on the Sacramento, Stanislaus, and San Joaquin Rivers, including the Shasta, New
Melones, and Friant Dams. The Bureau diverts CVP and State Water Project (SWP) water from
the southern portion of the Sacramento-San Joaquin Delta to the southern part of California.
Although the amount of water available from the CVP/SWP is relatively constant,
notwithstanding periods of drought and periods of excessive rain (e.g., El Niño years), the amount
of water diverted from major rivers and their tributaries has increased over time, and fish
populations have declined.
In the CVP/SWP watershed, the Endangered Species Act (ESA) protects multiple species or
populations of fish, including the endangered Sacramento River winter-run Chinook salmon, the
threatened Central Valley spring-run Chinook salmon, the threatened Central Valley steelhead, the
threatened Southern population of North American green sturgeon, and the threatened delta smelt.
The ESA requires the Bureau to consult with the Fish and Wildlife Service (FWS) or the National
Marine Fisheries Service (NMFS) (together, the Services) to see whether planned actions are
likely to jeopardize a listed species or damage critical habitat. (FWS is consulted for impacts
related to the Delta smelt. NMFS is consulted on potential impacts to salmon.) The consultation
process concludes with the Service issuing a biological opinion (BiOp) along with an incidental
take statement, allowing the federal action to proceed without prosecution for incidental harm to
listed species. If the Service finds the action is likely to jeopardize a listed species, a jeopardy
BiOp is issued, which will include reasonable and prudent alternatives (RPAs) to the planned
action to avoid extinction of a species. Otherwise a no-jeopardy BiOp is issued.
In 2004, the Long-Term Central Valley Project and State Water Project Operations Criteria and
Plan (OCAP) was issued by California and the Bureau to meet the system’s water needs. Pursuant
to OCAP, the Services issued both jeopardy and no-jeopardy opinions. Lawsuits challenged both
types of BiOp. If jeopardy was found, water users argued that the BiOp failed to consider impacts
on junior water users sufficiently. If no jeopardy was found, environmentalists and fishermen
argued that the BiOp did not fully consider the extent of the harm to the species. Judge Oliver W.
Wanger of the federal court for the Eastern District of California has found the BiOps or the RPAs
to be inadequate for various reasons, including failing to comply with the National Environmental
Policy Act (NEPA). (He retired from the bench at the end of September 2011.) Some of those
decisions have since been appealed to the Ninth Circuit, and oral arguments in the Delta smelt
case related to the FWS BiOp were heard in September 2013. New biological opinions are not
due until December 2015 (FWS) and February 2018 (NMFS), although those deadlines each
could be extended an additional year, according to a court order of April 2013. This report
summarizes the proceedings on the BiOps issued since 2004.

Proceedings Related to OCAP BiOps

Title Summary
NRDC v. Norton, 1:05-
1/3/07 Order
Denying
Despite the fact that new BiOps were being prepared by
cv-1207, 2007 WL
Motions for
both FWS and NMFS, the court refused to dismiss as moot
14283 (E.D. Cal. Jan. 3,

Remand, and
refused to stay Bureau’s operations to pre-2004 levels or

to consolidate suit against FWS with Pacific Coast
Federation’s suit against NMFS. (Bureau reinitiated
consultation with FWS on OCAP after new data on delta
smelt showed 2005 No Jeopardy BiOp needed to be
revisited. Bureau reinitiated consultation with NMFS after
species not listed at time of 2004 No Jeopardy BiOp
became protected.)
NRDC v. Kempthorne,
5/25/07 Order
The court held the 2005 FWS BiOp conclusion that delta
506 F. Supp. 2d 322
Remanding 2005 smelt were not in jeopardy was arbitrary and capricious
(E.D. Cal. 2007)
FWS BiOp
and remanded to the agency. The court found that the
BiOp’s take limits were based on inadequate historical data
that did not reasonably estimate the delta smelt’s
population. The court also found that FWS did not
consider available data on climate change and the possible
impacts on the smelt’s critical habitat. Final y, the court was
not convinced mitigation efforts were reasonably certain to
occur.
Pac. Coast Fed’n of
6/15/07 Dismissing
The court dismissed Plaintiff’s NEPA claim that the Bureau
Fishermen’s Ass’n/Inst.
NEPA Claim
was required to prepare an EIS for the 2004 OCAP. The
for Fisheries Res. v.
OCAP was a descriptive document rather than a final
