  1. Data Courtesy of U.S. Army Corps of Engineers.
  2. Month ranges represent the expected date range of passage for the species, estimated from the previous year's passage dates. Explicit date ranges limit the counts to that specific date range. The Chinook Run schedules are reported by USACE, ODFW and the YKFP.
  3. The Run Complete date is the last non-zero date of passage when the species has met the run complete criteria: 2 weeks (14 days) of zero passage for the species.
  4. Shaded rows represent subpopulations of the species as a whole.
  5. Last possible Data Date included is 12/30/2022.
  6. The 10 (or N) 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 from the previous 10 years on that calendar day is summed and divided by the number of non-null data points available. Calendar day averaging was chosen because, historically, data observations begin on a specific calendar day. Calendar day averaging gives different results than day of year averaging. YTD Averages and Total Averages presented in this report are the sum of the calendar day averages.

Notes:

  1. Year 2022 is incomplete. Data presented in Migration Timing Characteristics table is data through today's date.
  2. Data Courtesy of U.S. Army Corps of Engineers.
  3. Date Calculations:
    1. Query DART database for passage counts by Day of Year (not calendar date).
    2. Based on query results, calculate total number of fish for each year (reported as "Run Size" in table).
    3. Based on query results, calculate cumulative number of fish by day in the year.
    4. Based on query results, calculate the Day of Year when fish passage % is equal to or greater than the target percent, e.g., 5% passage. Passage % for a day = cumulative number of fish for day / total fish in year.
    5. For each individual year target passage percent, first date, and last date results: convert Day of Year to Calendar Date for given year, taking into consideration leap year. Report calendar date in table.
    6. For each individual year middle run duration: 80% duration = 1 + (90% Day of Year - 10% Day of Year), 50% duration = 1 + (75% Day of Year - 25% Day of Year), 90% duration = 1 + (95% Day of Year - 5% Day of Year). Report days in table.
    7. For each target passage percent, first date, and last date: calculate average Day of Year for that passage target percent from each individual year Day of Year values. Convert result into integer. Treat integer as Day of Year and convert into Calendar Date for a non-leap year. Report as Average.
    8. For each target passage percent, first date, and last date: calculate median Day of Year for that passage target percent from individual Day of Year values. Convert median Day of Year into Calendar Date for a non-leap year. Report as Median.
    9. Individual year calendar date values reported in table honor leap year. Calculated calendar date values (Average and Median) treat results as non-leap year dates.

Inflow, Outflow, Spill, and Temperature (Scroll Case) data are collected at the project (dam). Spill Percent is calculated by DART from the Outflow and Spill values. Temperature (WQM), Barometric Pressure, Dissolved Gas and Dissolved Gas Percent are measured at Water Quality Monitoring stations in the forebay and tailrace of most projects and other key locations in the basin (prior to 1995, these data are from a variety of sources within the U.S. Army Corps of Engineers). Turbidity is measured in the forebay or in the fish ladders at a project. Elevation is measured in the forebay of a project.

Bonneville Dam, 18 July 2006: The USACE initially reported incorrect hourly Bonneville spillway discharge for 2002-2004. DART is reporting the USACE's Recalibrated Spillway Discharge at Bonneville for this period. The Water Quality reports for BON, CWMW, CCIW, and WRNO include the recalibrated spill at Bonneville.

Wells Dam, 13 August 2012: The DCPUD has requested the water temperature data reported as the "Wells Scrollcase Water Tempurature" obtained for DART from prepared USACE text files be removed as erroneous. The Wells project does not report scrollcase water temperatures. This data has been removed from the publicly accessible DART dataset.

June 5 - July 9, 2013: DART reported partial averages for outflow and spill from several Upper Columbia PUD projects. These values have been corrected to show the average of the complete day. We would like to thank the CCPUD for helping us correct this issue.

Notes on the DART Adult Passage Dataset

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.

USACE Dams Video and Live Counting: From November through March, video tape fish counting occurs at 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 resumes 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, The Dalles, John Day, McNary, Ice Harbor, Lower Monumental, Little Goose, and Lower Granite: On March 10, 2011, DART's Adult Passage data from the Army Corps dams--Bonneville, The Dalles, John Day, McNary, Ice Harbor, Lower Monumental, Little Goose, and Lower Granite--were updated in their entirety (1938-2011) to reflect the numbers currently reported by the US Army Corps Portland District. The updates included replacement of manually entered data from printed reports, the inclusion of historical data previously missing from DART, and the correction of counts that have been updated.

Lyle Adult Trap at Lyle Falls: Daily counts represent number of fish caught in the adult fish trap at Lyle Falls Fishway (Klickitat River RM 2.4). With the exception of some fish that are collected for hatchery broodstock purposes, the vast majority of these fish are returned to the fishway to continue migrating upriver after sampling. The counts do not include fish that ascended the natural waterfalls or fish that passed through the fishway on non-trapping days. Some unknown-origin fish are recorded during fish counting that occurs as fish are returned directly to the fishway without handling or sampling. Data is provisional and subject to change following review and validation. http://www.ykfp.org/klickitat/Data_lyleadulttrap.htm

Willamette Falls Video Counting: Fish counting through Willamette Falls fishway occurs at the main viewing window. Video cameras and time lapsed video recorders are used to record fish passage 24 hrs/day, 365 days/year. The ODFW schedule for reviewing the tapes is Monday through Friday. It takes most of the day to accurately review one day of fish passage on tape when the counts are high.

Individual Status Reports

Bonneville Dam: Lamprey is the combined count from the fish counting windows at Bonneville, reported daily. LPS is the count from the Lamprey Passage Systems (LPS) at Bonneville. The fish counting windows and LPS are mutually exclusive. LPS are located at Bradford Island, Washington Shore and Cascades Island. LPS were opened in 2009 and counting started in June 2010. NOAA's LPS lamprey counts at Bonneville for 2011 are not available to the public until motion trigger images and data logger tallies can be compared to resolve the status of lamprey passage during data gaps and anomalous data series. This comparison is expected during the winter of 2011-12.

Mid-Columbia Lamprey: Douglas County PUD is currently planning to translocate lamprey (trapped at Priest Rapids Dam) upstream of Wells Dam for 5 years (2018-2022), and Grant County PUD is currently planning to translocate lamprey (trapped at Priest Rapids Dam) upstream of Rock Island Dam for as long as 10 years (2018-2027).

In 2022, Grant County PUD trapped 2,300 adult lamprey at Priest Rapids Dam and transported/released 1,500 of the fish upstream of Rock Island Dam. Douglas County PUD transported/released the remaining 800 lamprey upstream of Wells Dam. Therefore, the ladder counts for lamprey at Rock Island and Rocky Reach dams underestimate the actual numbers of lamprey that successfully passed both projects. The total lamprey passage for Rock Island Dam, with the translocated fish included, is 12,932 lamprey. The total lamprey passage for Rocky Reach Dam, with the translocated fish included, is 11,749 lamprey.

In 2021, Grant County PUD trapped 461 adult lamprey at Priest Rapids Dam. Douglas County PUD transported/released all 461 fish upstream of Wells Dam. The total lamprey passage for Rock Island Dam, with the translocated fish included, is 1,186 lamprey. The total lamprey passage for Rocky Reach Dam, with the translocated fish included, is 1,148 lamprey.

In 2020, Grant County PUD trapped 354 adult lamprey at Priest Rapids Dam. Douglas County PUD transported/released all 354 fish upstream of Wells Dam. The total lamprey passage for Rock Island Dam, with the translocated fish included, is 834 lamprey. The total lamprey passage for Rocky Reach Dam, with the translocated fish included, is 673 lamprey.

In 2019, Grant County PUD trapped 263 adult lamprey at Priest Rapids Dam and transported/released 111 of the fish upstream of Rock Island Dam. Douglas County PUD transported/released the remaining 152 lamprey upstream of Wells Dam. The total lamprey passage for Rock Island Dam, with the translocated fish included, is 1,330 lamprey. The total lamprey passage for Rocky Reach Dam, with the translocated fish included, is 1,058 lamprey.

In 2018, Grant County PUD trapped 851 adult lamprey at Priest Rapids Dam and transported/released 177 of the fish upstream of Rock Island Dam. Douglas County PUD transported/released the remaining 674 lamprey upstream of Wells Dam. Therefore, the ladder counts for lamprey at Rock Island and Rocky Reach dams underestimate the actual numbers of lamprey that successfully passed both projects. The total lamprey passage for Rock Island Dam, with the translocated fish included, is 5,849 lamprey. The total lamprey passage for Rocky Reach Dam, with the translocated fish included, is 5,892 lamprey.

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.

Tumwater Dam: Some video counts between 8/22/2011 9:19am to 9/05/2011 9:36am and between 9/23/2011 11:28am to 10/19/2011 7:52pm were not recorded, so passage counts during this period remain incomplete. Spring Chinook daily counts from 8/1/2011 - 9/15/2011 were adjusted to reflect know fallbacks from PIT tag analysis (M.Hughes, pers. com.).
Missing video counts: 7/27/12-7/30/12, 12/05/12-12/07/12, 12/17/12-12/21/12, and 12/29/12-01/01/13. Passage counts during these periods remain incomplete. Estimated sockeye passage during 2012: 66,520 fish. This run escapement includes an estimate for the number of sockeye that passed Tumwater during periods of missing video. Contact Travis Maitland for additional information pertaining to sockeye run escapement (WDFW, Wenatchee District Office, 509-665-3337).

Wanapum Dam, 2014:There were no adult passage fish counts at Wanapum Dam in 2014 due to a fracture discovered on the spillway in February 2014. The Reservoir elevation was lowered to reduce stress on the structure. The lowered reservoir made the regular fish ladder facilities and counting equipment inoperable. GCPUD was able to make modifications for fish passage at the dam, but a count was not taken at the dam.

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
  • 8/26/2008-9/21/2008
  • 8/23/2010-8/27/2010
  • 8/28/2020-10/5/2020: The Willamette Falls fishway was shut down for repairs from August 28 - October 5, 2020, which precluded passage above the falls. The extended fishway closure resulted in delayed migration and large numbers of fish holding below the falls. No pinniped activity was observed below the falls during this time period and no fish mortality events were reported suggesting the closure did not result in a significant loss in the fish population.

Zosel Dam

Zosel Dam 2017 data notes.
In 2017, the Zosel Dam video system did not begin operating until August 21, 2017, when the spillway gates were finally lowered and fish resumed full use of the fishways. Therefore, all of the steelhead run and the peak of the sockeye run were not counted in 2017. Gates were open: March 23, 2017 through August 21, 2017.

Zosel Dam 2016 data notes.
In 2016, the Zosel Dam video system did not begin operating until June 1, 2016, when the spillway gates were finally lowered and fish resumed full use of the fishways. Therefore, most of the steelhead run was not counted in 2016. Gates were open: April 8, 2016 through June 1, 2016.

Zosel Dam 2015 data notes.
In 2015, the Zosel Dam video system began operating on March 11, 2015, when the spillway gates were finally lowered and fish resumed full use of the fishways. Most of the steelhead run was counted in 2015 but counts may have been affected when gates were open from March 23, 2015 through April 3, 2015 and May 22, 2015 through June 10, 2015.

Zosel Dam 2014 data notes.
In 2014, the Zosel Dam video system did not begin operating until June 5, 2014, when the spillway gates were finally lowered and fish resumed full use of the fishways. Therefore, most of the steelhead run was not counted in 2014. Gates were open: February 15, 2014 through April 7, 2014 and May 3, 2014 through June 5, 2014.

Zosel Dam 2011 - 2013 data notes.
The Zosel Dam spillway gates were opened to allow for spring runoff during the periods of
May 7, 2011 through August 7; 2011;
April 26, 2012 through August 9, 2012;
and May 4, 2013 through July 20, 2013;
during which, an unknown number of salmonids may have passed through the spillway undetected by the video system.

Zosel Dam 2010 data notes.
  1. Equipment failure resulted in a loss of data from the right bank ladder (half of the sampling area at Zosel Dam, WA) August 25th through October 31.
  2. Linear regression was used to estimate the missed number of sockeye passing through the right bank ladder during the time data were lost (see Miller, BM, JL Panther, and JA Arterburn. 2010. 2010 Annual Report. Confederated Tribes of the Colville Indian Reservation, Omak, WA. located at http://www.cctobmep.com/media/files/2010_OBMEP_Annual_Report.pdf)
  3. No steelhead were observed in the left bank ladder during the time of equipment failure; therefore, no estimated number of missed steelhead were generated. Steelhead do not typically pass Zosel Dam during the time equipment failed.
  4. A relatively small number of Chinook were observed during the time of equipment failure, and it was not possible to use linear regression analysis to predict missed numbers of fish. Using the proportion of sockeye passing on the left versus the right bank ladders, potentially 127 Chinook passed the right bank ladder during the time equipment failed. However, there is no certainty associated with this number, therefore this estimate was not included in the total number of Chinook reported for 2010.

Zosel Dam 2008 data notes.
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.

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.
