Fish Passage Center Adult Dam Count Queries

The FPC Adult pages contain dam count data for salmon and steelhead, adult passage Pit Tag detections, Fishermen's Links webpage, fishing forums and much more. The FPC adult count data collection program searches for new adult passage data every 30 minutes in the morning, and every hour in the afternoon and evening, 7 days a week.

USACOE Counting Metadata for the COE Dams

During the fish passage season (April through October) the USACOE uses visual counting from 0400-2000 PST, during periods with daylight savings time this time is actually 0500 to 2100. The COEs QA/QC program involves a one hour test each month for all fish counters. During this test, both the tested fish counter and the fish count supervisor each count each species passing for one hour. The tested fish counter must score within 95% of the counts recorded by the fish count supervisor for all species other than shad which is within 85%. During visual counting, fish counters typically get a 10 min break every hour; therefore, counts over a 50 minute period are multiplied by a factor of 1.2 to obtain an estimate of a full hours counts. In addition, the identification of spring, summer and fall Chinook is determined by the dates set by the COE in the following table:

Notes

  • For Historical Data (past years), there were days where no adult fish were counted at the ladders. On these days, we did not add a record to our database. If a zero count adult salmon date occurred during the counting season (varies by dam), then it can be assumed that there were zero fish counted for all adult salmon and steelhead species at the ladder in question.
  • *Unclipped steelhead counts start in 1993. On 8/20/99, the steelhead counts for Well, Rock Island and Rocky Reach Dams were changed to reflect total steelhead instead of hatchery steelhead. This is consistent with the other Dams.
  • Unclipped steelhead are a subset of steelhead. Unclipped steelhead are counted separately from hatchery steelhead at Corps dams on the Columbia and Snake Rivers. Unclipped steelhead are identified as fish with an intact adipose fin. However, a small number of hatchery fish may not have had their adipose fin removed.
  • Adult Chinook are counted separately from jack Chinook. Adult Chinook are set at 22 inches or longer. Adult Coho are counted separately from jack Coho. Adult Coho are set at 18 inches or longer. Adipose fin clipped Chinook (adults and jacks) are counted separately from wild Chinook. Same for Coho. Same for Steelhead (except there are no adult and jack sizes in Steelhead).
  • Since the year 2006, Priest Rapids Dam and Wanapum Dam jack counts have included mini jacks.

How Frequently Data are Updated

  • The data is updated Monday through Friday during the season. However, several of the sites are several days behind in reporting, but the data is reported by the Army Corp of Engineers as zero. So where zeros appear across all rows, the data should be considered as "not yet available."
