This web site is a collaboration of multiple agencies in the Mid Columbia River region to bring together juvenile and adult salmon information with river conditions for improved management of the region. Data is from Columbia River DART and provided courtesy of Chelan County PUD, Colville Tribes Fish & Wildlife (OBMEP), Douglas County PUD, Fish Passage Center, Grant County PUD, U.S. Army Corps of Engineers, NWD, U.S. Fish & Wildlife Service, U.S. Geological Survey, Washington State Department of Ecology, Washington State Department of Fish & Wildlife, and Yakama Nation.

Notes on the DART Adult Passage Dataset

Early Season Notice Video tape fish counting is now being being made at most US Army Corps of Engineers dams with fish ladders on the Columbia and Snake Rivers. Fish counting by video tape takes at least a few days to process: the fish counters have to make, collect, and read the tapes, and then submit their fish counts. DART retrieves and posts the data as soon as it is made available. On April 1, live fish counting will resume at all 8 Columbia River and Snake River Corps dams with fish ladders: from April through October each year for 16 hours each day, fish counters working at each fish ladder look directly into the fish ladders to count the fish passing by.

Bonneville Dam, 1960, 1965, 1966: On 22 January 2009, Bonneville Dam adult passage counts for 1960, 1965, and 1966 were synchronized with the Annual fish passage reports of the U.S. Army Corps of Engineers, North Pacific Division

Rocky Reach Dam, June 8-9, 2005: Video was lost at Rocky Reach Dam from 1751 hours on 8 June and was not returned to operation until 0729 hours on 9 June. As a result, the adult passage counts at Rocky Reach Dam are incomplete for both days.

Wells Dam, Lamprey Research, 2007-2008: The Lamprey adult passage counts at Wells Dam are not reflective of actual run size during 2007-2008. Trapping, monitoring, and research efforts at Wells Dam artificially lowered the passage numbers for Lamprey; i.e., more fish would have passed without tagging and trapping efforts.

Willamette Falls: The Willamette Falls fish ladder was not operational on the following dates: 11/29/2005 - 12/1/2005, 12/6/2005 - 12/8/2005, 12/13/2005 - 12/14/2005, and 8/26/2008 - 9/21/2008.

Zosel Dam: Zosel Dam estimated 2008 adult sockeye passage counts missed due to equipment malfunction.

15 May 12:00 - 20 May 12:00 = 0
17 Jul 00:00 - 18 Jul 19:00 = 6678
09 Aug 10:00 - 12 Aug 12:00 = 649
31 Aug 00:00 - 04 Sep 10:00 = 570
Total Missed Sockeye count = 7897
Initial 2008 Sockeye count = 77533
Revised 2008 Sockeye count = 85430
At this time, missed sockeye counts are not reflected in query results.

USACE Data Disclaimer: These data are furnished with the understanding that the Corps of Engineers makes no warranties concerning the accuracy, reliability, or suitability of the data for any particular purpose.

Tumwater Dam: Adult passage data for Tumwater Dam is the combination of released counts, referring to fish passed upstream of the dam and allowed to spawn naturally, and collected counts, referring to fish retained for hatchery broodstock. The Chinook adult passage counts are the sum of hatchery spring, hatchery summer, wild spring, and wild summer chinook as reported by WDFW and Chelan PUD. The Jack Chinook adult passage counts are the sum of hatchery spring, hatchery summer, wild spring, and wild summer jack chinook as reported by WDFW and Chelan PUD.

Steelhead Counts: The Steelhead parameter includes both hatchery and wild counts. Prior to 1995 wild steelhead data was not published on a daily basis. The Steelhead-Wild parameter is a subset of the total steelhead and may include unmarked hatchery fish.

Chinook Run Dates: Chinook runs (referring to the season when adults migrate upstream) are based on run schedules by project as established by the U.S. Army Corps of Engineers and Yakima Klickitat Fisheries Project. Sp = Spring, Su = Summer, Fa = Fall

Calculating the 10 year averages: The ten year averages are calculated by DART for each calendar day of data at each project. For the current year and any given project/month/day, the data is summed from the previous 10 years and divided by the number of non-null data points available during that 10 year span.

Notes on the DART Trap Dataset

Trap Data Disclaimer: These data are preliminary and have been derived from various sources. These data are furnished with the understanding that the primary sources make no warranties concerning the accuracy, reliability, or suitability of the data for any particular purpose. The counts presented on this web site are the raw collected counts at the traps; no expansion factors or trap efficiencies have been applied to the raw collected counts.
