Condit Dam Facts• Built in 1913• 92 acre reservoir• 2.4 million cubic yards (1.8 m3) sediment• Watershed = 390 square miles• Average flow of 1000 cfs• Draining will take 6 hrs at 11,000 cfs (~ 100 yr flood event)• Highest flow recorded was 45,000 cfs in 1996•Much of the river is in a narrow basalt canyon• Once passable for fish it will open33 miles for steelhead 14 miles for chinook
Overview White Salmon
Working Group
Focal species
Options identified
Options recommended
Science guided plans
White Salmon Working Group An update of fish salvage and reintroduction plan was
necessary
Working group was formed and first met in February 2007
Information sharing and identification of reintroduction options
Coordination of fish salvage prior to removal
Pre and post removal monitoring and evaluation
Opportunities to work with partners on fisheries and habitat restoration in the basin
Species considered: summer and winter
steelhead fall Chinook salmon spring Chinook salmon coho salmon chum salmon bull trout pacific lamprey
Options considered:1) No action, natural
colonization, re-evaluate in 5-10 yrs
2) Salvage wild fish and outplant above Condit Dam, prior to removal
3) Salvage wild adults, spawn in hatchery, release juveniles in White Salmon River after removal
4) Use adjacent hatchery/wild stock, release juveniles/adults in White Salmon River after removal
Options recommended by the White Salmon Workgroup
Summer and winter steelhead, and spring Chinook salmon - monitor natural escapement, re-evaluate options in 5 years
Conclusions Options incorporated into NOAA’s Endangered Species Act
recovery plans for Middle Columbia River steelhead and Lower Columbia River Chinook, coho, and chum salmon
The existing datasets and findings provide some information prior to reintroduction, much more could be learned
Two types of tags for tracking fish in theWhite Salmon subbasin:
Passive Integrated Transponder (PIT) Tags&
Radio TagsRadio Tags
Uniquely identify individuals.
Can be read from longdistances.
Cannot be put in smallfish.
Tags are expensive.
Battery life is limited.
PIT Tags
Uniquely identify individuals.
Cannot be read fromlong distances.
Can be put in small fish.
Tags are not expensive.
No battery, lasts the life of the fish, or longer.
