Significant Benefit Hundreds of “on the ground” habitat projects based
on recovery plans with demonstrated biological benefits
New hatchery actions to promote recovery and regional fisheries, without impeding recovery of listed fish.

similar to 2000 BiOp, except for:
Implementation of summer operations at Libby and Hungry Horse dams recommended by the State of Montana
Work on dry water year strategy for Grand Coulee Dam
John Day – Operate John Day pool at the lowest elevation that continues to allow irrigation from April 10 through September 30.
Lower Snake – Operate at minimum operating pool (MOP) elevation from April 3 until small numbers of juvenile migrants are present unless adjusted to meet authorized project purposes.

Spill Spill OperationsOperations
Spring 24-hour spill at all
projects Lower Snake
collector projects–spill ceases for two weeks in May for transport of steelhead
Continue testing of spill as new surface collectors come online
Earlier transition from spring to summer spill
Summer Similar spill levels as in 2006–2008 Snake River projects–Cessation of spill in August when few fish are present (300–500)
14
Juvenile Fish Transportation Program
Spring Chinook typically benefit from transportation after approximately April 20
Steelhead typically benefit from transport throughout the season
Fall Chinook research is in progress
Sockeye has too little data to tell

Litigation: NWF v. NMFS, Corps, & Reclamation
Remand completed with issuance of 2008 BiOp on May 5
Court-ordered hydro operations remain in effect until Aug 31, 2008
NWF et al. filed complaint against NMFS with U.S. District Court of Oregon, challenging new BiOp
Plans to sue Corps and Reclamation challenging compliance with ESA and CWA
Briefing on the merits will begin mid-summer; schedule is being set to allow time for preliminary injunction hearing before the end of calendar year
Anticipate PI to be broader in scope than mainstem spill operation

Resulting Transport Operations
Spring Operations Spill and Bypass April 3 – April 20 Spill and Transport April 21 – May 6 Maximized Transport May 7 – 20 Resume Spill and Transport May 21 ~ June 1 or until
Fall Chinook predominate
Summer Operations Spill and Transport (~June 1 ~ Aug 31) In August, spill will be curtailed after Aug 1 when
fewer than 300 juvenile fall Chinook per day are collected
