• 2.9 million Green

Lake fry @ .76 grams

BY12 COHO BY13 COHO

75,688 broodstock approved for spring release.

104,000 hatched alevin in incubation

PLC Hatchery Alarm screen

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
