Work Element Usage Report

K: 28 - Transport of Upstream And Downstream Migrants-Umatilla Basin

The project operates the lower Umatilla River trapping facilities (Three Mile Falls Dam and Westland trapping facility) in order to collect broodstock and transport salmonid migratory life stages around passage barriers. The project also transports broodstock to program holding facilities. The project provides dates of trap operation and migrant trap and haul data. Three Miles Falls Dam is the major collection point for all adults returning to the Umatilla River. The main collection facility is located on the east bank and includes a holding pond, fish handling and sorting complex. Captured adults to be transported are directed to transport tanks for hauling. The east bank facility is manned 24 hours a day during the adult capture season. Permanent, on site housing is provided for watch personnel. The west bank at Three Miles Falls Dam does have an adult collection facility and a juvenile collection facility operated by the ODFW outmigration monitoring and evaluation project. However, the west bank at Three Mile falls Dam does not have the adult sorting capabilities. The west bank juvenile collection facility was designed as a sampling and evaluation station rather than a production trapping facility. The trap can be used for sampling during bypass periods but is ineffective for trapping and hauling anything but small numbers of fish. Because of the insufficient trapping capabilities at the site, the operation of the facility is closely coordinated with the Westland facility in order to minimize the number of fish captured at Three Miles Falls Dam. The Westland Canal juvenile facility is the major collection point for out-migrating juvenile salmonids. It is intended to be operated whenever Westland Canal is delivering water. During periods of inadequate flow, the facility is designed to trap fish, separate juveniles from adults, and direct them to their respective holding units. Juveniles and kelts can then be loaded onto trucks or trailers for transport downstream. Information collected at Westland include dates of both canal operation and facility operational modes. Because the majority of the fish are now bypassed at Westland juvenile facility rather than trapped, the facility is no longer manned on a 24 hour basis.

Operate both adult and juvenile traps as needed and safely transport broodstock to various holding facilities and transport both adult and juvenile salmonids to various release locations during low flow periods.
