Meta Identifier	LTRDFish
Type of Data	Downstream migrant trap data and Chinook adult redd and carcass surveys
Originator	Six Rivers National Forest
Description	Fyke traps (1991-1993) and rotary screw traps (1994-2002) operated for extensive periods annually (data were extracted from annual MS Excel files, and annual reports). Trap calibration in recent years allows population estimates. Water temperature and flows recorded in some years. Spawning surveys also conducted on some tributaries (data were extracted from annual reports, there is also a separate MS Access database for each year).

Maint. and Update Freq.	Annual
Serial Name	NA
Purpose	Spawning use, habitat availability and juvenile production of Chinook salmon in Lower Trinity and lower South Fork Trinity tributaries
Data Quality Information	Traps efficiency may vary with flow but calibration since 1995 allows population estimation of downstream migrants. Larger steelhead juveniles may avoid the trap and may be underestimated. Spawner survey data may vary because effort depends on flows.
Use Constraints	None

Abstract	NA
Other Citation Details	Downstream migrant trapping data for Willow and Horse Linto Creeks from 1991-1998. Adult redd and carcass counts for Willow, Horse Linto, Madden, Sharber-Peckham and the lower SF Trinity. The later two only began being surveyed in 1998.
