Trinity River Hatchery Trapping Summary Update for Feb. 5-11
The update shows the numbers of fish processed at the Trinity River Hatchery. The Willow Creek weir and Junction City weir are not operating.
Total combined Chinook has remained at 0 since December 17, 2014.
Total combined Steelhead slightly increased from 91 to 93..
1. Hatchery summaries are not always posted on a weekly basis due to the large amount of data collection and entry.
2. All hatchery totals are complete counts of what has been processed at the facility.
3. Hatchery totals do not include fish which are being held in on-site ponds for ripening and future spawning.
4. There is a break in spawning operations, usually in October, to facilitate separation of spring and fall-run Chinook salmon.
5. The hatchery serves as the main recovery point for fish tagged at the two weirs (Willow Creek and Junction City).
