  1. Nez Perce Tribal Hatchery Complex Program Overview Nez Perce Tribe Department of Fisheries Resources Management

  2. Confederated Tribes of the Umatilla Indian Reservation Teamwork

  3. NPTH Purpose • Develop, increase, and reintroduce natural populations of spring, early-fall, and fall Chinook in the Clearwater River Basin. • Sustain long-term preservation and genetic integrity of target fish populations. • Keep the ecological and genetic impacts of nontarget fish populations within acceptable limits. • Provide harvest opportunities for Tribal and non-Tribal anglers.

  4. SCS goal: 825K release 200K Yearlings from NPTH into Clearwater River 150K Presmolts from Yoosa/Camp AF into Lolo Creek 75K Presmolts from Newsome AF into Newsome Creek 400K Parr from NPTH into Meadow Creek (no acclimation) FCS goal: 1.4M release 500K subyearlings from NPTH into Clearwater River 500K subyearlings from North Lapwai Valley AF into Clearwater River 200K subyearlings from Luke’s Gulch AF into S.F. Clearwater River 200K subyearlings from Cedar Flats AF into Selway River NPTH Production Goals

  5. NPTHC Area of Influence

  6. Nez Perce Tribal Hatchery • Constructed in June 2000 through Oct. 2002 • Four ground water wells • Four surface water pumps • Eight Krebs sand filters • Zero Gravity filter System • UV system • Chiller • Automated temperature control • Backup Generator

  7. Sweetwater Springs Early rearing facility • Used by IDF&G until 1978 • Upgraded and used by NPT beginning in 1993 • Officially transferred in 1998 • Further modifications in June – December, 2001

  8. North Lapwai Valley Acclimation 500K FCS subyearlings • Constructed in Dec. 2000 through Sep. 2001 • Located on Lapwai Creek near Clearwater River • Pumped Lapwai Creek water

  9. Luke’s Gulch Acclimation 200K FCS subyearlings • Constructed from May through August 2001 • Located on S.F. Clearwater River • Partial setup/takedown • Portable pumps & Generator

  10. Cedar Flat’s Acclimation 200K FCS subyearlings • Complete setup/takedown by NPTH staff each year • Located on Selway River • Portable pumps & generator

  11. Newsome Creek Acclimation 75K SCS presmolts • Constructed from Jun. 2000 through Sep. 2001 • Located on Newsome Creek…tributary of S.F. Clearwater River • Gravity fed creek water

  12. Yoosa/Camp Creek Acclimation 150K SCS presmolts • Constructed from Jun. 2000 through Sep. 2001 • Located at Confluence of Yoosa & Camp Creeks (tributaries of Lolo Creek) • Gravity fed water from both creeks

  13. Meadow Creek (Selway River) 400K SCS parr • Direct stream release • Helicopter outplanted

  14. Flow of Fish NLV AF Subyearlings Clearwater River 500K 500K NPTH NPTH 1.0M 500K NPTH Subyearlings Clearwater River 500K 1.64 Million Green Eggs NPTH NPTH Luke’s Gulch AF Subyearlings S.F. Clearwater River 400K 200K 200K Sweetwater Springs LGD Cedar Flats AF Subyearlings Selway River 200K 200K Clearwater Hatchery NPTH NPTH Yearlings Clearwater River 200K 200K 200K Clearwater Hatchery Clearwater Hatchery 200K Meadow Creek 750,000 Green Eggs Lolo Creek Weir 400K NPTH Yoosa/Camp AF Presmolts Yoosa Creek Other Sites 150K 150K 550K NPTH NPTH 625K Sweetwater Spring Newsome AF Presmolts Newsome Creek Newsome Creek Weir 75K 75K 75K

  15. Planned: Low density index Mimic stream temperatures Pathogen & silt free river water Natural “S” channel rearing Natural pond substrate Exercise program Volitional release Currently Used: Low density index Partially treated river water Natural “S” channel rearing Natural pond substrate “S” channel only exercise Volitional release “NATURES” Rearing

  16. Things That Work • Incubation temperature control • Early rearing temperature control • Low density rearing • Well control • Variable drives • Automated and prioritized • Hatchery Automation • Round tanks • “Low impact” acclimation sites

  17. Things That Didn’t Work • Acclimation site adult holding/spawning • Hatchery Automation • Some natures components • Stream temperature incubation • Exercise program mostly abandoned • No predation control • “S” Channels not culture friendly • Production based on 100% expected water use • Lack of flexibility in engineering

  18. Key Challenges • Well water issues • Acclimation site intakes • Limited river water treatment • Filtration limitationsUV limitations • Undersized heat exchanger • SCS adult holding mortality • Missing weirs • Broodstock collection • Program evaluation

  19. So You Want To Build A Hatchery? • Budget some “extra” production water • Design every component for flexibility and adaptability • Hire your Manager before you build • Assemble a Technical Work Group in advance • Label every component in fish culture speak • Write your SOP in fish culture speak • Demand a water/alarm system map • Think long term and outside the box • Energy efficiency • What are the private growers doing? Our neighbors to the north?

  20. Biggest key to success?
