FOBEWORD 

The basio purpose of this report is to fumish information on the 

passage of fiSh, operation of fish faoilities and other activities 

carried on during the year in oonneotion with the migration of fish at 

Bormeville and McNary Dams. The fish-passage facilities at Bonneville 

Dam. have been in operation for 19 years, and at McNary Dam. for 3 y-ears. 

Included herein are summaries of fish oounts by species for eaoh 

calendar year of operation. New material in tables and graphs is 

presented in similar form. as in previous reports to provide a oontinuity 

ot comparable data. Brief descriptions are also inoluded of investigations and research performed during the year at eaoh dam to asoertain 

the habits of fish, ability to reaoh spawning grounds above the dams, 

and survival of fingerlings passing downstream. 

F1ates and photographs are included to illustrate the various 

features of the work and aotivities in detail and to olarify data on the 

physioal features and operational prooedures at eaoh dam. Table and 

plate numbers of previous reports are retained as nearly- as possible in 

this report for rea~ oomparisons. 

This report is distributed to biologists, fishery agenoies, universities, libraries and others interested in these fisheries, within the 

limits of oopies printed and requests received. The use ot abstraots or 

data ~ this report is per.missible provided credit for the souroe i8 

given to the Corps of Engineers.

ANNUAL REPORT ON THE PASSAGE OF FISH 

BONNEVILLE AND MoNARY DAMS 

CALENDAR YEAR 1956 

BONNEVILLE DAM 

Summary 

1. During the fish-counting season of 1956. 814.801 tish ot 

various speoies were oounted passing upstream by means of the fish 

taoili ties at Bonneville Dam. This total is the lowest ootmt since 1945 

and somewhat less than the 19-year average ot 940,815. Only the bluebaok 

total exceeded the 19-year average ot 110,679 for this speoies. 

2. The salmonid OOtmt ot 595,275 oomprised 300,917 chinook, 

156,418 blueback, 6,127 silver, 693 chum, 4 humpbaok, and 131,116 steelhead trout. The total ot 219,526 miscellaneous tish was below the 

19-year average ot 321,167. 

3. The spring run total ot 63,449 ohinook was below the 19-year 

average ot 81,025. The summer run total of 111,483 ohinook was the 

highest of record and exceeded the 19-year average of 53,555. The fall 

run total ot 125,985 exceeded the fall run totals of the previous three 

years. See table 26. 

4. Yearly totals of all fish which ascended Bonneville Dam during 

the period 1938-1956, inclusive, appear in table 1. Monthly totals for 

1956 are listed in table 2. Daily records, b,y months, are oompiled in 

tables 3 to 24, inolus ive. Peak days of fish migration, by species, for 

the period 1938-1956, inclusive, are shown in table 25.

·1 

5. The maxVnum number at salmonids cOlmted in one day (15,104) 

were cOlmted on July 5, and the maximum number at miscellaneous fish 

(12,084) were oOlmted on July 9. The maximum number ot a.ll species 

cOlmted in one day (25,115) were cOlmted on July 9. 

6. Monthly OOlmts ot salmon and steelhead trout tor the period 

1938-1956, inolusive, are shown in tables 26 to 30, inolusive, and 

misoellaneous speoies oounted over the SBme period are shown in table 31. 

7. More than a toot at snow tell by the _d of January. There 

were severa.l snow storms during the month of February and some snow fell 

in l~ch. In February, the temperature fell to 100 F., the highest 

temperature, 1030 F., was reoorded in July. A month without preoipitation 

is unusual at Bonneville Dam. Only a traoe ot moisture was reoorded in 

July. A total of 76.90 inohes of preoipitation was reoorded in 1956. 

8. Fish-oounting was initiated on March 1 and discontinued at the 

end ot the day, Deoember 1, 1956. As in previous years when fish-oolmting 

was discontinued for annual winter maintenance of fish faoilities, at 

least one oomplete fishway system was continually aocessible for the 

mlimpaired passage ot upstream migrants. 

9. Biologioal experiments were continued in 1956 by the U. S. Fish 

and Wildlife Servioe to transplant upriver spring chinook in Wind River, 

Washington. Approximately 500 spring ohinook salmon were transported to 

the holding pool at r,yee Station, Carson, Washington, fbr artifioial 

propagation. An exoellent hatohing and rearing peroentage was attained 

with the eggs obtained tram the 1966 fish. The experimental tisheries 

. researoh laboratory adjacent to the Washington shore fish ladder, whioh 

2 
• 

was oomp1eted in 1955, was op'erated by the U. S. Fish and ~ildlif'e 

Servioe in 1958. 

10. Additional phases of' e~erimentation on submerged oritioe~ were 

oarried on by Bonneville f'oroes under the researoh program at the powerhouse oolleotion system during 1956. Also, in turtherin~ the tinger1ing 

survival researoh, numerous young salmon were passed'through the spillway 

and tUrbines by means ot the gossamer bag, selt-inflating balloon 

teohnique. Muoh greater sucoess was attained at the spillway by the use 

of a new timer utilizing 8.ll.hydrous (water soluble) polyethylene glycol 

E 4000 (carbowa:x:) as one of the timer construction components. In another 

surn val experiment" one group ot adult carp" with delayed action seltinflating balloons attached to eaoh fish, was passed under the spillway. 

11. On plates 1 to 4" inolusive, are shown the daily fish oounts 

of' the four prinoipal salmoni~ speoies tallied at Bonneville and MoNary 

, 

Dams in 1956.

BONNEVILLE DAM 

Spring Chinook Salmon 

(March 1 - May 31) 

13. The spring chinook run ot 63,449 tell below the 19-year average 

ot 81,025, and considerably below the record-breaking run ot 171,596 

spring chinooks ot 1955. See table 26 and plate 1. Table 25 shows the 

daily peaks ot abundance in comparison with peaks ot other years. 

14. Table 32 shows the number and percentage ot the spring run ot 

1956 which ascended each fish ladder. The percentages ot the spring run 

to the total run tor 1966 and other years are shown in table 33. 

Plate lS illustrates the trend of spring chinook counts. 

Summer Run Chinook Salmon 

(June 1 - August 15) 

15. The summer run developed into a record-breaking total ot 

111,483 chinooks. The 19-year average is 53,655. During the past three 

years this rlm has been inoreasing. See table 26 and plate 1. Perc entages ot summer run ohinook tor 1956 and tor the period 1938-1956, inclusive, are shown in tables 32 and 33. Plate 14 shows the ascending trend 

ot ~ummer run chinooks. 

Fall Chinook Salmon 

(August 16 - December 1) 

16. The tall run total exceeded the previous 3-year tall runs, but 

the 1956 total ot 125,985 chinooks was considerably below the 19-year 

4 
, ) 

average ot 218.696. The peak of 8.924 wa,s reaohed on September 6. See 

tables 25 and 26. Plate 15 illustrates the trend ot tall ohinook OOtmts. 

17. A oonsiderable number ot tall ohinook passing Bonneville Dam 

are destined tor hatoherios within 25' miles upstream. In 1956. only the 

Spring Creek Ba tohery obtained the usual number of eggs or a take of about 

31,681,000· eggs. 

18. Table 33 shows the number and peroent of the totals of the 

spring, summer and fall ohinook r1m8 for the period 1938-1966, inolusive. 

The dates selected as beginning and ending of the respeotive rtm.s are 

someWhat arbitrary but the,y have been in use for a number of years and 

racial laps are recognized for tish arriving before or after these datese 

Se. plate 16. 

Chinook Jacks or Grilse 

19. At Bonneville Dam, small male ohinook salmon, approximately 

16 to 18 inches in length, are tallied as jack salmon or grilse. Of the 

1956 ~otal ohinook rtm., 13.72 percent were jacks. In tables 34 and 35, 

jack s~lmon are listed separately from larger fiah. The 1956 total of 

41,274 jack salmon 1s slightly above the 19-year average of 40,736. 

Bluebaok Salmon 

20. The blueback cotmt of 156,418 in 1956 exceeded the 19-year 

average of '110,679. The peak of abundance was reaohed on July 6 when 

12,958 ascended the fish ladders. ,It will be noted in table 36 that 

60.96 percent of this species ascended the Bradford Island ladder and 

5 
49.06 perca:t" the Washington shore ladder. See also tables 25 and 27" 

and plates 2. 6 and 17. 

Silver Salmon 

21. Although the 1956 total of 6,,127 silTers exceeded the count. of 

the previous two years" it 1I'B.S below the 19-year average ot 7" 871. 

Plat. 18 shows the deoline in abundance ot this species. Data on silver 

salmon are shown in tables 1, 2, 25, 28 and S7, and plates S, 7 and 18. 

Chum. Salmon 

22. The ohum salmon total of 693 is oonsiderably above the 1965 

total of 318, but less than half of the 19-year aTerage ot 1,567. 

See tables 1, 2, 29 and 38. This run develops late in the year. Fish ... 

oOUlting 1I'B.8 disoontinued on December 1, 1956 while a significant number 

ot ohUIII. salmon 'll'8re still moving upstream. The cOtmt at Bonneville Dam 

theretore is not indioat'.ve of the total run. 

Humpbaok Salmon 

23. Only four of these "pink" salmon asoended the tish ladders at 

Bonneville Dam. in August and September; two were tallied at the Washington shore oOUlting station and two at the Bradford Island OOtmting 

station. See tables 1 and 2.

Maximum. Abtmdanoe and Yearly Peroenta;ses of' Salmonids 

Cotmted Over Eaoh Fish Ladder 

25. The maximum number of' fish of' all speoies oounted in one day 

in 1956 was 25,115, oounted on July 9. See tables 13 and 14. Of' this 

total, 4,401 salmonids and 3,827 misoellaneous f'ish asoended the 

Bradford Island ladder, and 8,630 salmonids and 8,257 misoellaneous f'ish 

asoended the Washington shore ladder. 

Population Trends ot Salmonid Speoies at Bonneville Dam 

26. The population trends of' salmonid speoies tallied at Bonneville 

Dam are illustrated on plates 13 to 22.. inolusi vee This analY'sis mayor 

may not be indicative of' the total ab1.D1da.nce of' these speoies in the

27. An upward trend will be noted in the spring and surmn.er runs of' 

chinook and steelhead trout, as well as the entire steelhead and blueback: 

rtms. A downward trend is noted in the tall ohinook and steelhead runs, 

and in the entire silver salmon and shad rtms.

Misoellaneous Speoies 

Shad 

28 •. The total of 8.085 shad was oonsiderably below the 19-year 

average of 16.335. See tables 2, 31, 42. 43 and 44; also plate 23. A 

small number of shad died and were washed against the Bradford Island 

weir 47 oounting fence during high flows. As usual, these fish followed 

a behavior pattern which has indioated little effort to go on upstr~. 

However. in 1956. four shad reached McNary Dam. This species has been 

observed in the Bonneville forebay as late as January and/or February. 

but it is not known whether these fish will on occasion remain in tresh 

water the year aroUDd. 

Smelt 

29. No smelt were observed at Bonneville Dam in 1956. During the 

period March 29 and April 11 a sizable rUD entered the Sandy River whioh 

flows into Columbia River approximately 25 miles downstream trom 

Bonneville Dam. 

Lamprey 

30. The total of 49.911 lampre,ys whioh asoended the fish ladders in 

1956 was subaverage; the 19-year average is 80.929. See tables 2 and 31. 

The number of lampreys that reaoh the forebay through the oOUDting 

barriers whioh obstruct the oounter's view is unknown. Uany lampreys 

died and were washed against the weir 47 oounting fence as in 1965. 

Sturgeon 

31. Forty-four sturgeon reaohed the foreb~ via the fish facilities; 

four ascended the ladder leading to the U. S. Fish and Wildlife Service 

laboratory situated on the Washington shore, one ascended the Bradford

.. 
.,. 

Isla.nd ladder. and 39 were lifted in the Washington fish look. 

See tables 2 and 31. 

32. At the request at the Oregon Game Commission, 226 live sturgeon 

were obtained and tra.usp1anted in a northern tributary ot Klamath Lake. 

The _jori ty at these ganoids were brought to the surfaoe when. the draft 

tube stop logs ot unit 2 were ra.ised prior to overhaul. 

33. On August 9, a. small sturgeon, heavily infested with Cystoopsis 

sp. parasites, was taken from. a powerhouse draft tube stop log. 

See photo 2. Several years ago speoimens ot these parasites were taken 

trom. 8 turgeon a.t Bonneville Dam a.nd sent to the Sm.:l thson:la.n Institution 

in Washington, D. C. 

34. Heretotore, the water regulation orew and biologists suspeoted 

that mder very s peoia.1 oondi tiona ti sh moved through the powerhouse to 

the toreba.y. On August 17, sturgeon were fomd on she1Tes or reoesses 

of the downstream. side of unit 10 intake tube gates while preparations 

were under war for placing the unit in opera.tion to1lowing overhaul. 

These fiSh travelled from. the previously-opened draft tube, between the 

motionless turbine blades, and thenoe through the open wioket ga.tea to 

the intake tube. Smelt have reaohed the torebay under sim.ilar oiroumstanoes •

Aotivities and Observations 

Fish Looks 

36. The Washington fish look was operated intend ttaD.tl)" during 

August and September to capture sturgeon :tor the Oregon Game Commission. 

Presumably very :tel'll sturgeon were in the vioinity as only 39 were lifted 

in this look.. The other tWo fish looks were operated infrequently to 

oheck funotional ability. 

Powerhouse and Bradford Island Awtili!9' Water Soreens 

3? Inoreased quantities of debris in the river oaused oonsiderable 

diffioulty at the stationary auxilia.ry water intake Bcreens. Even with 

two washings per day.. it was impossible during the flood season to keep 

the screens clean. Therefore, it was neoelllary at times to throttle the 

large primary radial valves that supply the water to the auxiliary water 

oonduits in order to proteot the filter soreens whioh, in turn, resulted 

in an inadequate water supply to the powerhouse fish oolleotion system.. 

Fis~oountiDg Sohedule - 1956

dq, December 1. 

Deo. 2 - Deo. 31 - Fish were free to pass upstream through the 

open counting gates. 

Forebay and Tailwater Levels 

39. water was spilled through the main spillW8¥ gates until 

August 19. Auxiliary fish attraotion water \I'IlS spilled through gates 1 

and 18 tmtil Ootober \ to oreate better attraction flow near the spill~ 

oolleotion system entrances. 

Fish Faoili;ty Repairs and Overhaul 

40. Major overhaul to the powerhouse colleotion BYstem was acoomplished in the fall of 1956. 

41. On January 3, 1956, the Washington oolleotion system wa. 

UXl\'I8.tered to working level. In suooeeding 'Weeks, the following 'WOrk _s 

aooomplished: 

a. Fifteen diffusion ohamber timber battles were replaced. 

b. Valves and stems of diffusion ohambers 13 to 19, inclusive, 

were removed, cleaned, painted and adjusted. 

c. Vertical tiJllber battles in diffusion chambers at elevation 

minus 10 were reconstructed, and a new type of baffle -.s installed with 

double anohorage for t1m.ber posts in diffusion chamber 16. 

11 
d. New rubber seals were placed on the _trance segmental 

gates of the fish lock. 

e. Cleaned and painted the radial filling gates in the equalizing chamber of the auxiliary water supply system. All fixed steel in the 

auxiliary water chamber was cleaned and painted. 

f. Overhauled the mechanical screen pump. 

g. New discharge troughs were constructed and installed to 

guide the water used tor washing stationar,y screens aW8¥ from the 

meohanical screens. 

h. Radial gate No. 5 (Washington fish lock drain valve) was 

removed from its shaft, sandblasted, cleaned and painted. Rivets were 

driven into the skin plate. new rubber seals were installed) trunnions 

were freed, and a new greasing system was installed for pitmans and gibs 

of the actuating arm. 

i. Regulating beadgates were removed, then cleaned and 

painted. Hoist chains of weir 82 were cleaned and inspeoted. 

j. stop log storage slots at the head of the Washington fi sh 

ladder were cleaned and painted. 

42. Upon completion of the above work, the area 'WaS flcoded on 

February 14, and the ladder was rewatered on February 18. 

43. On January 16, sizable holes were drilled into the new steel 

bonnets, which cover diffusion valves being installed in the Washington 

fish~, so that the bonnets could be bolted to fit tightly and held 

permanently in place. This area was not lmwatered during the fall of ) 

1956, henoe, the results of the tolerance of these bolts will not be 

known for a year or more. 

12 
44. On February 20. the Bradford Island ladder was drained to tailwater to permit the removal of silt. repairs to worn baffles. and for 

cleaning and painting. Very fn fish were fO\D1d in the ladder. The 

ladder was rewatered on February 27. Photo 3 shows a view of the upper 

ten weirs of the "An branoh of the Bradford Island ladder in operation. 

45. During the spring freshet, the 'Right of water in the fishwa.y 

exit of the experimental laboratory pushed the wooden ladder from the 

wall thus necessitating repairs Whioh were diffioult under the oiroumstances with water in the fi.shwa.y. Permanent repairs were made when the 

ladder was tmwatered toward the end of the year. 

46. Telephones were installed in the Bradford Island and washington 

shore fish-oounting stations on April 20 to enable the fish oounters to 

furnish information readily to the seourity office and/or to gain 

assistanoe in the event of an emergenDY'. For instance, on May" 18, when a 

surge of water in the forebay flooded the Bradford Island oounting house. 

the shoCk disengaged the telephone reoeiver-transmitter apparatus thus 

sounding an alarm in the seouri t;y offioe. A seouri ty guard was dispatched 

to the oounting station after reoeiving no response from the fish counter 

and assisted her to safety. 

47. This surge of flow at forebay level caused water to run down 

the roadways on eaoh side of the fiahway. However, the submerged orifice 

regulating weirs at the upper end of the ladder prevented a wall of water 

from racing down the fish ladder to the weir 47 oounting station. The 

water rose only to the floor of this lower OOtmting station, and the 

fish oounter retreated to higher level before getting wet. During a 

somewhat similar surge of flow in February 1948, a oounting station. 

13 
tortunately lmoccupied, was lost when it was carried away trom its 

position in the Washington shore ladder. 

48. Two additional impeller-t,ype water velocit,y indicators were 

installed to aid in the regulation ot powerhouse collection system. water 

flOWB during the summertime experiments. See photo 4 ot the 1955 &mlual 

report. 

49. The screen barriers ot bay 1 were removed to permit floating 

and removal 01' the spill~ batfle repair caisson. On March 7, it was 

towed away and the screen barriers immediately replaced. 

50. On May 31, with a tlood flow 01' 711,600 c.t.s. and tailwater 

level 01' 44.6 teet, the barriers ot bay 1 were again removed as it was 

anticipated that gate 1 might be opened several latches to spill water. 

The maximum tlow ot 816,000 c.t.s. was reached on Jlme 4, but it _s 

UDDecessary to use gate 1 to distribute the flood .ter. 

51. A great quantity ot mud was discovered in the Washington shore 

fish trap on Deoember 10, 1956, which, it is believed, oontributed to the 

second breakdovm ot the year. This damage was repaired prior to trapping 

and transporting spring ohinook by the U. S. Fish and Wildlite Service. 

Aotual trapping was initiated on May 4 and disoontinued on Mq 8, 1956. 

52. Eaoh summer, tive units ot the powerhouse are overhauled. 

Draft tube stop log slots are lowered betore the soroll case and draf't 

tubes are lmwatered. A number 01' tish ot mixed species are usually 

trapped in this area. These tish are salvaged ~ the resident biologist 

and released, alive, if possible, in the torebay. 

63. On Jlme 21, it was discovered that salmon were leaping into 

reoesses on the downstream side of gate 1 whereupon this gate was closed 

14 
until the soreen barriers were replaced on August 8. Later, the gate was 

opened six inohes in order to improve fish attra.otion oonditions. 

54. In November, the fish facilities south of the powerhouse were 

UDII8.tered; worn rubber seals were replaced, radial valves 3, 4, 5 and 6, 

and the brail of the fish look were removed, stripped, sandblasted and 

painted. 

56. In November and Deoember the Washington Shore fish ladder was 

1.ll'IIIB.tered for extensive overhaul of the upper regulating gates and 

controls. 

Speoial Fishery Investigations 

SUbmerged Orifice Research 

66. The powerhouse oollection system experiments were oontinued in 

1956 with three additional tests of operation. Two of these tests were 

supplemental to and repetitions of tests performed in 1955. The 1956 

tests were as follows: 

a. Normal transportation flow versus one-half nonnal flow. 

b. Large-sized orifices versus medium-sized orifices. 

c. lS-inch head versus 12-inch head. 

The experiments which were conducted during the late spring months were 

hampered by an inadequate supply of water in the fi sh colleotion system. 

ParadOxically, when river water is most abundant during flood season, 

the least amolmts of water are available for fish attraotion. Salmon 

were observed (from the submerged observation ohamber) entering the 

submerged orifices with a minimum of effort against an lS-inoh head. 

15 
Submerged Floating Oritice 

67. Planning and design ot a submerged f'loating oritice tor use in 

one of the powerhouse collection system entrances were tmder 'W'B.Y' in 1956. 

In the near tuture a se1t-regulating f'loating orifice will be constructed 

and tested tor meohanioa1 feasibility. Suoh an orifice, set at optimum. 

depth, shotlld be more adVantageous to fish passage. 

Fingerling Pressure Tests 

68. The preliminary tests started in 1956, subjecting small fish to 

pressure as a part of the fingerling survival experiments, were oontinued 

in 1966 at Bonneville Hydraulio Laboratory in oooperation with the U. S. 

Fish and Wildlife Servioe, Taooma City Light and the Washington Department } 

ot Fisheries. Groups of different sizes of fingerling salmon, attar bei~ 

held at specified pressures over night, were suddenly decompressed to 

pressures beloW' atmospherio, and withstood the conditions of the tests as 

imposed. 

Balloon Teohnique Experiments 

69. Numerous fingerling survival experiments using balloon and 

gossamer-bag technique were oonducted at Bonneville Dam during 1956. 

Improvements in technique and timers reduced spillway mortality to about 

one-half of the 1954 results. A tew exper1ments were conducted at the 

powerhouse where no signifioant mortality was indicated in the passage 

through the turbines. In 1964, the piokup boats operated very olose to 

the ~ Consequently, many balloon units Which had not yet inflated 

passed mseen beloW' the boats and were lost. In 1956, the boats were 

stationed from four to six miles beloW' the dam. Wi th the aid of the 

improved timers and other new teohniques, in two experimental rlDlS the 

16 
peroentage of recovery of balloon and bag units oontaining fish which 

passed through the spill~ rose to 87 and 94 percent, respectively, 

toward the end of the experiments. 

60. Theae tingerling survival studies appeared to demonstrate a 

d1tterence between the north and south half or the spillway stilling basin. 

Less mrtality ooourred in the test runs in the south half of the spillway 

where nR batfles were constructed in 1954. Experiments will be oontinued 

in an effort to develop a mre etfeotive meohanical timer which would 

inorease the percentage of reoovery. 

Carp ExReriment 

61. Adult oarp, supplied by the Oregon Game Commission and U. S. 

Fish and Wildlife Servioe biologists, were used in lieu ot salmon in 

another balloon and gossam.er-bag .tuq. A number of adult oarp. with 

gossamer bags and self-inflating balloons attaohed, were sent through the 

spil11l8.7. Some were reoovered by boatmen below the dam, but many balloons 

became detaohed from. the dorsal spine of the oarp. 

Batohe;r Fingerling Releases 

.. 

62. Al though several million chinook fingerling salmon were flooded 

out of the ponds of the Spring Creek Hatchery as the torebay level rose 

and other fingerlings were migrating during the high _ter period, there 

was relatively little 10s8 of fingerlings on the auxiliary water soreens. 

It was learned frcm previous experienoe that by throttling the a.uxiliary 

water valves during this period the fingerlings were to some extent proteoted. No aea gulls were shot in 1956 for stomaoh analysis. 

17 
Rate of Fish Movement 

63. On May 1. 1941. a temporary ladder in the "An branch of the 

Bradford Island fish ladder was opened and the first ten fiah were timed 

ascending the ladder to the f'orebay. One hour and nine minutes of elapsed 

time was recorded as the ra.t8 of ascension of' the ladder from tail_ter 

to the forebay. Numerous details ot features of the facility and this 

experiment are tmknown. 

64. On July lS, 1956, appro:dmately 2,900 fish were released trom 

the collection pool at elevation plus 5S and permitted to ascend the 

Washington shore ladder to the forebay. 

weir 60 in the experimental facility. 

In one hour, 2,400 had passed 

The median elapsed time ot movement 

trom weir 54 to weir 60 was 20.3 minutes, and 1,600 of the fi sh counted 

were salmonidsJ the remainder were miscellaneous or scrap tish. The 

majori ty ot the experimental ti ah ascended 2S weirs to the torebay in 

73 minutes. 

Eleotronio Fish-counting Devioe 

65. On January 17, 1956, t1llO representatives of the Audio Products 

Corporation ot Los Angeles, California. damonstrated an eleotronio fishcounting devioe. Harmonic readings were recorded at the downstream tace 

ot the powerhouse tor use in case electronio oounting oritioes are 

install ed in the future. 

Tagging Program by Oregon Fish Commission 

66. The Oregon Fish Cmr.m1saion carried out a tagging program. under 

oontraot wi. th the Corps ot Engineers. near the Washington shore oounting 

station. See photo 4. The fish were led into a tloating trap whioh _s 

towed to a float one hundred yards or more upstream where the f1 sh were 

18 

.. 
.. 

dipped out, tagged and released. A number of holes developed in the wire 

mesh leads. Nearly all of the season's run of bluebacka esoaped betore 

the holes were discovered and repaired. Thia program was oonducted to 

determine the migration time between Bonneville and MoNary Dams prior to 

oompletion of The Dalles Dam. 

Fatigue Experiments of Fish 

/ 

67. The university of Washington Sohool of Fisheriea, '1mder oontraot 

with the Corps of Engineera, oonduoted experiments at the Fisheries 

Laboratory in Seattle to determine the fatigue time of salmon. A number 

of blueback salmon were oaptured in the Washington shore fish look and 

the Oregon Fish Commission trap and hauled to Seattle for these fatigue 

studies. In addition, blood and tissue samples were taken. from several 

bluebaok by p~siological chemists performing related work. 

Fingerling Mortalitw Investigations 

68. Tattooed fish, with different marks, used in fingerling survival 

experiments were released by the Washington Department of Fisheries 

through and below MoNary Dam. and oolleoted at several points in sooop 

nets do1lllstream., inol uding Bonneville Dam. These experiments indioated 

some mortality through the powerhouse, but little, if an.y, at the spillftY' • 

U. S. Fish and Wildlife Servioe Activities 

Soreen. Pit Fingerling Experiment 

69. Sinoe 1945, studies have been oarried on at Bonneville Dam. by 

the research staff of the U. S. Fish and Wildlife Servioe in oooperation 

wi th the Washington Department of Fisheries to learn the migration habits 

ot fingerling salmon. In 1956, several thousand tattooed fingerling 

19 ,-
salmon were released in the Bradford Island and Washington shore mechanioal 

screen pits to learn by what means fingerlings enter the by-passes where 

inclined plane traps are located to capture them. Very fffW fingerlings 

were reoovered. It was theorized that the fish entered the forebay 

through the trash raoks. 

North Shore Laboratory 

70. The U. S. Fish and Wildlife Servioe operated the north shore 

laboratory in its first full yaar during 1956. Numerous unexpeoted 

oiroumstanoes and diffioulties were overoome. Potentialities of the 

facHi ty were gained by experience. and numerous experiments were conducted. The twenty-pen Esterline Angus operations reoorder or chronograph, 

which determines the approximate rate ot travel of fish through the 

darkened area, was loaned to the north shore laboratory personnel to 

reoord the passage of individual or groups of fish. This devioe has not 

been used sinoe the tunnel experiments ot 1948. 

Tests of Sonar Equipment 

71. The U. S. Fish and Wildlife Servioe conduoted a number ot tests 

wi th sonar equipment in the Washington shore laboratory. In addition, 

several experiments were made in the laboratory by attaching small sonia 

transmitters to fish. Also. a test was made of eleotrioal fingerling 

barrier soreens. 

Draft Tube Trap Experiments 

72. The U. S. Fish and Wildlife Servioe made preparations to oontinue these experiments for the purpose ot determining whether a quiokrelease tyke net. DIOlmted on the draft tube trap. could capture both live 

20 
and dead fish. This apparatus would not enter the water rushing trOlll the 

draft tube so the experiments were abandoned. 

Squawfish studl 

13. Ma.uy' squawtish were oaptured by U. S. Fish and Wildlife Serriee 

personnel at Bonneville Dam. and held in a local hatchery pond pending 

transfer to Seattle for stu~. 

Danil Ladders 

14. S8'f"eral experiments were conducted by the U. s. nsh and Wildlife Service on the two small Denil fish ladders which were oonstructed 

and operated in the north shore laboratory. This partioular type of 

ladder oan have a much greater gradient than normal fish ladders. 

Other Aotivities at Bonneville Dam. 

Observations of Turbid Water 

15. On July 13, a oloudburst over Mitchell, Oregon, resulted in the 

discharge of a vast muddy mass of water into the John Day River, and 

thenoe into the Oolumbia River. On July 14, tor approximately 20 miles 

below John Day River, a reddish-colored m.ud, oarried out at the John Day 

.. tershed, f'lowed into the Columbia River. On July 15, this red, densely 

turbid m.aas of water reached Bonneville Dam.. Seoohi disk readings of 

0.2 ft. were reoorded. For a time, fish movement over the dam virtually 

ceased. 

Request for Steelhead by Washington Department ot Game 

16. The Washington Department at Game requested 150 to 500 unscaned 

steelhead trout tor artificial brood stock in its new Washcugal River 

hatchery. Because tish capiJured in the Washington fish look were likely 

21 
to beoome injured, approx1mate17 ten tiab. were seleoted trom' the Oregon 

Fish Commission trap toward stooking this hatohery. 

S;wimmjng Abilitr ot Steelhead 

77. On one oooasion during the operation ot the Bradford Island 

fish look, with water spilling out ot the shatt at elevation plus 30, 

and tailwater at eleTation plus 13 (a differenoe of 17 feet), two steelhead trout entered the fish look like fly:i.ng fi sh. Such tram.endous 

swimming ability' has never betore been observed at Bormeville Dam. 

Striped Bass 

78. During the operation ot squawf'ish gill nets, the U. S. Fish and 

'Wildlife Servioe oaptured a 2l-inoh striped baSI at the mouth of Hamil ton 

Creek, approximately ale mile belOW' Bormeville Dam. None have been 

observed my oloser to Bonneville Dam. in the past.

the spring run 1I8.S rea.ohed cn May 21 when 1.112 chinook were cO'lmted. 

The spring run ot 14,603 ·was 12.77 peroent ot the total chinook run. This 

is considerably below the 35.42 percent average tor the years 1954 and 

1955. See tables 70 and 71, and plates 1 and 9. A breakdown ot the 

number and percent of chinook salmon which ascended eaoh ti sh ladder 

appears in table 76. 

Summer Run Chinook Salmon 

(June 16 - August 31) 

94. The summer run ot 92.299, the highest summer count since tishcounting was initiated, was 80.72 percent ot the 1956 total ohinook run; 

52.27 peroent ot this r'lm asoended the Oregon fish ladder. The peak was 

reaohed on July 1 when 5.361 chinook were oO'lmted. The 1954 and 1955 

Bummer runs were 56.79 peroent ot the 2-year total salmon runs, and the 

1954-1956, inc1uB;i,ve, summer r1mS were 64.61 percent ot the 3-year salmon

Fall Chinook Salmon 

(September 1 - Deoember 31) 

95. The tall r1m peak of 473 was reached on September 11. The 1956 

tall run total of 7,440 'Was 6.51 peroent of the total ohinook run, 

26 
7.36 peroent of the 3-year average, and 7.79 peroent of the 1954 and 1955 

average. See tables 70, 71 and 76; also plates 1 and 9. 

Chinook Jacks or Grilse 

96. These small male ohinook salmon are tallied separately but are 

inoluded in allot the chinook oounts. Table 77 shows the number and 

peroent of ohinook jack salmon counted over each fish ladder. Of the 

total chinook run, 21.19 peroent were jacks. A ma:x:imum length ot 18 

inches was established in 1954 tor jaoks and -'8 changed to 24 inohes for 

the 1955 and 1956 jaoks at the request ot the Oregon nsh Commission.

and in 1956, 43 pero8l1t. 

S1l T8r Salmon 

98. A total ot 683 silver salmon asoended the ladders at MoNary Dam 

in 1956: the peak ot 32 was reached on September 17. Tables 70 and 73, 

27 
and plates 3 and 11 give pertinent data on this speoies. The average 

annual COlmt tor the years 1954 and 1955 01' 797 is intluenoed by the 1954

Chum Salmon 

99. No chum salmon were observed at MoNary Dam in 1956. 

Steelhead Trout 

100. The 1956 total of 42,554 steelhead trout is lower than. either 

ot the previous two years and below the 3-yoar average ot 67,729. The 

daily peak 01' 967 was reaohed on August 10; also August. was the peak month 

with a COlmt ot 14,492. See tables 70 and 74, and plates 4 and 12. The 

peroentage use 01' each fish ladder is Shown in table 80; 64.S8 percent

Maximum Abundance and Yearly Percentages of Salmonids 

Counted Over Each Fish Ladder 

101. On July 10, 23,618 fish of all species were comted; the maximum 

number counted in one day in 1956. This total oomprised 2,487 ohinook, 

72 steelhead, 9,160 blueback and 11,899 misoellaneous tiBh. The maximum 

number 01' salmonids (11,719) was counted on July 10; the maximum number 

ot miscellaneous tish (21,613) on July 21. See tables 69 and 60. 

102. The yearly peroentage use at tish ladders by all salmonid 

speoies tor the years 1954 to 1956, inolusive, is shown in table 81. 

28 
Miscellaneous Species 

Shad 

103. Shad were recorded tcr the tirst time sinc. tish-counting was 

ini tia:ted at McNary Dam. Four shad asoended the Oregon tish ladder; two 

on July 19 and two on August 8. See tables 60 and 62. 

other Misoellaneous Speoies 

104. Fifteen misoellaneous speoies ot tish other than salmonids, 

totaling 645,184, or more than double the salmonid OOlmt, asoended the 

MoNary Dam fish ladders in 1956. The 3-year average is 765,345. s •• 

tables 45, 46 and 75. SuCkers, although decreasing 39 peroent trom the 

1955 oount, were again the most numerous &mOunting to more than balf ot 

the total misoellaneous fish COlm.... The mos'" remarkable inorease is in 

... he number of carp which increased from 0.4 peroent in 1954 to 20.3 percent in 1956. 

Aotivities and Observations 

Generator Installations 

105. By the end ot the year all 14 generating units 'Were in plao. 

and units 1 through 12 .... r. in operation. This extended the tailrace flow 

pattern almost the length ot the powerhouse. All uni ... s are expeoted to 

be in operation by the time there is suffioient water in 1957. 

Washington Fish Look 

106. The Washing'ton tish look was used tor the tirst time since construction as a primar,y fish-passage facility. For a Short period during 

the summer of 1956 this lock 1II8.S used in conjunotion with experimental 

work. 

29 
Pressure Fish LoOk 

101. This look was operated intermittently but no salmonids were 

passed b,y this taoility.

Flood Conditions and Colleotion Chaanel Operations 

109. .An extremely heavy spring rtmoff in 1966 raised the tailwater 

elevation above operating limits of the powerhouse collection channel 

weirs. See photo 6. The upper limit of operation for these weirs, With 

all segmental gates in p1aoe, is tal1water elevation 216 feet, the same 

height &s the oonorete bulkheads in the closed bays. The tai1water 

elevation peaked at over 218 feet during the spring .freshet. See photo 6. 

Fish-0011ection facilities oontinued to operate with no apparent delay to 

fish passing upstream. 

Fish Faoi1itr Repairs and Overhaul 

110. Rubber seals were p1aoed in the leaking oonstruction joints in 

the Washington fish ladder. These seals did not prove satiaf'a.ctory. A 

semi-plastio sealant will be tested on a oonstruction joint for oontraotion and expansion during the next umvatering season. 

111. Dials whioh indioate open and closed positions were installed 

on the operating meohanism of all rotova1vas. 

112. A leak whioh developed in one of the valva pits of the Washington shore gravity supply systan was fOlmd to be oaused by oavi tation 

through the supply pipe above the rotovalve. Water pressure then eroded 

through the conorete surrolmding the pipe and into the val ve pit. Investigation shawed other pipes to be atfeoted by oavitation. A seotion of 

pipe and surrounding concrete is to be oore-dri11ed tor further inspeotion. 

113. New steel bulkhead-type stop logs were oonstruoted in the 

entranoes to the Washington shore ladder. These stop logs, made to the 

31 
size of three wooden-t,rpe stop logs, were fitted with rubber seals to 

more etteotively stop the leakages when the lower end ot the ladder is 

unwatered. 

114. Following the nood runotf, it was tomd that the trash rack in 

tront of the gravity water supply oondui t leading to the Washington fish 

look .tilling 'Valve had been plugged with debris sufficiently to prevent 

filling the lock. After removal ot this debris, it was possible to fill 

) 

the look to toreb~ elevation. 

115. Due to the accumulation ot trash, the screen covering the 

pioketed section at the north and ot the powerhouse ccllection ahaDnel 

was removed so that collection channel transportation water would pass 

thrcugh the screen in cpen-type operation. 

116. The trash booms at the two exits ot the Oregon fish ladder were 

literally shaken apart by wave action trom strong north and east winds 

and were replaced with booms ot much sturdier construction. 

Special Fishe;r Investigations 

Oregon Fish-collection System Studies 

117. This st~, initiated in 1955, was continued in 1956 to determine whether the addition ot more operating generator units changed the 

pattern of fish entering the collection system. The results ot this 

series ot studies corroborate the tindings ot the previous year. These 

investigations indioate that the majority ot upstream migrant salmon and 

steelhead enter at both ends ot the powerhouse collection system but 

relatively tff1W enter the center section. It was also noted in comparing 

the entrance pattern ot 1956 with the previous year that the fiah 

32 
to11owed the draft tube discharge ettect as these disoharges moved northward due to the installation ot additional operating generator unit •• 

Travel Rate ot Chinook Salmon in Oregon Fish Ladder 

118. An attempt was made to determine the travel rate of' ohinook 

salmon at various points in the Oregon tish ladder b.r reoording the 

counts at 10-minute intervals and determining the t:1.me interval between 

corresponding peaks at each location. Results of these preliminar,y tests 

indioate that (1) the t:1.me spent b.r chinook salmon in each pool averaged 

about 2.6 minutes, and (2) based on the rate ot 2.6 minute, per pool, the 

average travel rate was 7.7 feet per minute. 

Fingerling !v-pass Tests 

119. In March, a trap was built and installed in one ot the two e*i ts 

ot the fingerling b,y-pass ..vstam of the Oregon fish ladder. See photo 7. 

This system diverts d01lDstream migrants into the Oregon ti sh ladder paEit 

the traveling screens of the grav1t,r attraction water supply system. The 

primar,y purpose ot this experiment 'Was to determine the time of d01lDstream 

migration ot ditterent species ot salmonids, and to test the eftioiency 

ot the b7-pass s7stam. The trap was raised dai17 while do1lDstream 

migrants were pres ant. The peak ot the downstream movement was reacheJ 

in May" tor ohinook, blueback, and silver salmon migrants. Twent7-tour 

species ot tish were captured. This trap will be operated again during 

the 1957 season. 

Submerged Orifice Operation ot Oregon Fish Ladder 

120. During the period of Jul7 16 to 21, an experiment was conducted 

to dete~e the reaction of fish in passing through a transition area in 

a ladder trom normal overtlow to submerged oritioe floW' onI7. The lower 

33 
eight wairs of the Oregon fish ladder were operated 'IIIi th overflow oonditions and the upper 67 weirs a.a submerged orifioes only. See photo 8.

This experiment indicated that operation ot the Oregon fish ladder with 

the outlined flow oonditions caused no signifioant change in the migration 

ot salmonids through the fish ladder nor was there ~visible evidence 

ot f'ish acoumulation at any point in the vioinity of' the oolleotion IIYlttem 

entrances or within the transportation system and fish ladder itselt. 

Washington Fish Lock 

121. An experiment waa oonduoted tor a tew days during the summer 

r\81 to oompare the attraction ettioiency 01' the look and ladder entranoes. 

Screena were placed across the fish ladder immediately upstream of the 

look entranoe and the fish were passed through the look tor a 24-hour 

period. The soreens were then raised and the fish permi~ted to pass up 

the ladder tor the subse~uent 24-hour period. This alternate pattern was 

performed tor 10 ~s when the laok of fish brought the experiment to a 

olose. 

ateelhead Tagging Studies 

122. Biologists at the Oregon Fish Commission, assisted by MGlary 

Dam personnel, tagged 746 steel head in the Oregon ladder and released 

34 
them into the forebay. Two channel catfish were also tagged and released. 

Migration of Salmon Past The Dalles Dam Site 

123. A study was initiated in 1956 under the Corps of Engineers' 

research program to determine whether the travel rate of' upstream migrant 

salmon and stee1head would be effected by The Dalles Dam. See paragraph 66. 

Adult salmon and stee1head were tagged by the Oregon Fish Commission at 

Bonneville Dam and reoovered at McNary Dam by operating a trap at the exit 

of' the Oregon f'ish ladder. See photo 9. Part of this investigation will 

be repeated in 1951 atter the forebay of The Dalles Dam is raised. 

Fingerling Mortality Studies 

124. The Washington Department of Fisheries continued in 1956 

experiments under the research program. to determine the extent of mortality. if ~. to migrating salmon fingerlings passing downstream through 

the turbines and spillways of McNary Dam. As in 1955, specially-marked 

fingerlings were recovered by nets tram barges located at several downstream points. Improved procedures for "mixing" the oontrol and experimental groups were used during the spillway plants in 1956. No measurable 

mortality was noted among fingerlings passing through the spillway as a 

result of the 1955 and 1956 experimental plants. and mortality of fingerlings passing through the turbines was approxilDate1y 11 percent. These 

studies were conducted under a contract with the Corps of Engineers and 

will be oontinued in 1951 at Big Cliff Dam on the North Santiam River 

using fingerling and yearling salmon. 

35 
Inspectian oE FiSh Eor Sy!ptoms of Co1umnaria 

126. Members of the Miorobiology Department of the 1h1versity of 

Washington visited Mollary Dam on several oocasions during the bluebaok 

salmon run to ~ne speoimens for Co1umnar1s. Several bluebaok salmon 

were found to be infeoted. 

Blueback Blood Charaoteristios Samples 

126. Twsnt,y adult blueback salmon were dissected and preserved for 

imraediate transportation to the University of Washington in Seattle for 

blood oharaoteristios and other studies. At the same time. 40 live adult 

bluabaok: salmon were transported to the Sohool ot Fisheries at the 

university tor fatigue tests. See photo 10. 

Chinook Tagging 

127. The Washington Department of Fisheries tagged fall ohinook 

salmon whioh were obtained £'rom the trap maintained by the Oregon Fish 

Commission for migration rate experiments. This tagging experiment was 

oonduoted to determine the spawning areas ot the fall chinook that pass 

McNary Dam. 

Holding Chinook Salmon for Ripening 

128. In September, six ohinook salmon were removed trom the trap in 

the Oregan fish ladder and transported to the Washington tish lock to 

determine whether ohinook oould be held and ripened in river water at 

MoNary Dam.. This cperim,ent was oonduoted in conjunction with the proposed artifioial spawning ohannel to be built below MoNar,y Dam. The lock 

was tilled with water to provide a large live box. Two tamales, one male 

and three jack salmon were p1aoed in the fish look. The tish were held 

about seven weeks during which period one female died from f'tmgus. 

36 
The rest at the tish ripened sucGesstully and the eggs ... ere stripped and. 

shipped to the experimental hatchery at the Atomio Energy Commission 

plant at Hanf'ord, Washington. 

Winter Resident Fingerling Salmon 

129. A gill net was used by a biologist ot the Washington Department 

ot Fisheries in the torebay ot MoNary Dam to determine whether there ... ere 

&IV downstream. migrant salmonids in the pool area during the winter. 

These periodio checks were made in November and Deoember and will be oontinued, 1I8&ther permitting, during the winter ot 1956-57.
