Topic Fish: Horse Linto Cr Downstream Migrant Trap Popn. Estimates 1994-01
Caption:  The chart above shows the number of juvenile Chinook salmon and steelhead estimated to have outmigrated during the trapping season at the Horse Linto Creek fish trap for the years 1994 and 1996 through 2001. Juvenile Chinook outmigration showed an impressive and steady increase every year between 1994 and 2001. Steelhead 1+ estimates were relatively constant in the three years for which they were made. Weekly outmigration estimates are made by adding the number of fish caught to an estimated catch for days when trap was not operating, and then dividing by trap efficiency. Weekly outmigration estimates are then added together to produce an estimate for the trapping period (typically late March through August). Steelhead outmigration estimates were only calculated in 1994, 2000, and 2001. No trapping was conducted in 1995. Data provided by the Six Rivers National Forest, Lower Trinity Ranger District.
