Chum Incubation
Survive to Ponding
•Deep Inlet 4.0s • 8,500,000
Broodstock 4.0 • 3,570,709
Deep Inlet Regulars • 44,700,000
Broodstock Regulars • 15,266,329
Total: 72,037,000 103% of goal
BY13 CHUM-Bear Cove
•18.8 million broodstock
• Finished ponding
almost 6 weeks earlier than last year.
• Growing very well at 2.5%
• Very warm water temperatures @ 7.5-8 degrees C.
BY13 CHUM-Deep Inlet
•53.2 million fish
• Early ponding but very small fish.
• Growing very well at 2.7% -.46g average
• Early release/size goals should be easily met
• Finished all transfers 10 days before we started last year
Discovery and prevention
•Chinook holding in A-ponds for acclimation during transfers from the lake (see graph)
•Treatment plan in the lake for trycophyra

Mortality by Netpen
BY12 COHO BY13 COHO
75,688 broodstock approved for spring release.
21.12gram average as of February 27th.
104,000 hatched alevin in incubation
Chinook incubation re-vamp to fit additional 9 million chum expansion
Pursue additional in-stream intake in north fork of stream and other
potential water
enhancements
Airlift baffle construction
for fall coho holding
Continue looking for ways to cut
energy costs given this summers
rate increase
Blue Lake penstock shutdown planned for August 24th
Medvejie will be holding 1.1 million additional 12 gram coho for two months which will need an additional 7 cfs of water
Preparations Airlift baffle construction/o2 supplementation Back-up diesel pump Possible new instream intake Pray for rain-snowpack prayers unanswered
