FOREWORD 

The data assembled in this annual report on the passage of 

fish, operation of fish facilities and other activities in connection 

with fish migration at Bonneville Dam. summarizes factual and other 

pertinent information for calendar year 1952. Summaries of the fish 

counts by species for each calendar year. 1938-1952, inclusive, are also 

included. 

Copies of these annual reports are distributed to fiBher.Y 

agencies, libraries, and others within the limits of copi"s printed and 

requests received. 

Many of the summary tables and graphs herein are presented 

similarly to those in previous reports, including the addition of new 

material obtained in 1952, thereby providing a continuity of comparable 

data. 

A series of plates and photographs are included to illustrate 

various features and activities, and to clarif'y the report for those who 

are not thoroughly familiar 1d. th the physical features and operational 

procedures of fish facilities at Bonneville ~.

ANNUAL REPORT ON 'l.BE PASSAGE OF FISH 

BONNEVILLE DAM 

. CALENDAR YEAR 1952 

Summa:17 

1. The number ot salmonids which migrated upstream by means of the 

fish facilities at Bonneville Dam during the calendar year of 1952 _s 

the largest in the history of the project, partly due to record-breaking 

runs of steelhead trout and blueback salmon. The fall count was affeoted 

by the oommeroial fisher.men's strike whioh took plaoe from August 12 to 

August 26. 

2. All of the salmonids and ~rious other species oounted during 

the year totaled 1,075,326 fish. This is oonsiderably more than the 

annual average of 921,862 fish over the preoeding 14-year period, 1938-

1951, inolusive. The annual averaee for the l5-year period, 1938-l~52, 

inolusive, was inoreased to 932,094 fish. 

3. The salmonid oount of 875,796 oomprised 420,879 ohinook, 

260,990 steelhead, 184,645 bluebaok, 7,768 silver, 1,505 chum and 9 humpback. Miscellaneous other fish totaled 199,530, which is muoh less than 

the previous average of 346,023. 

4. The 1952 spring run of ohinooks has been exoeeded only onoe; 

the summer run exceeded all previous years sinoe 1938, but the fall run 

of Chinooks _s sub-average. See table 26. As a result of the oombined 

management praotioes of all agencies concerned with fish, it appears 

that there is an inorease in the number of bluebaok and spring and 

surmner runs of ohinook. Annual totals of all fish passing upstream over 

-1-
Bonneville Dam during the period, 1938-1952, inclusive, appear in 

table 1. Monthly totals of all fish which migrated upstream over Bonneville Dam in 1952 are listed in table 2. The daily records by months 

are compiled in tables 3 to 23, inclusive. The number of fish counted 

(~ species) on peak days for the period, 1938-1952, inclusive, are 

shown in table 24. The days of maximum abundance of fish counted over 

each fish ladder are shown for the period, 1938-1952, inclusive, in 

table 25. Monthly counts of salmonid and steelhead trout for the period, 

1938-1952, inclusive, are shown in tables 26 to 30, inclusive, and miscellaneous species counted over the same p~riod are shovm. in table 31. 

5. Mild w~ther prevailed throughout the year with a subnormal 

amount of rainfall. A total of 53.93 inches of precipitation was 

recorded. Only short periods of freezing weather were experienced. 

6. Fiah-counting was initiated on March 1 and discontinued on 

November 29, 1952 for annual winter maintenance of fish !'acilities. 

During periods that fish were not counted, at least one compl"ete fishway 

system was contint.lly accessible for unimpaired passage of upstream 

migrants. 

7. Three biological investigations'were conducted to obtain 

factual information on the habits of fingerling and adult salmon and 

their tolerances under certain laboratory and field conditions. 

-2-
Spring Chinook Salmon 

8. Spring chinook appeared at Bonneville Dam much later than 

usual. The peak of abundance was reaohed on May 27 when 7.594 chinook 

were counted. During the conunercial fishing season, extending from 

~April 30 to June 7. it was reported that the commercial fisheries reaped 

a rich harvest; many of the fishermen informed personnel at Bonneville 

Dam that this was the ~est season in their experience. One fisherman 

reported catchi~g one ton per night for eight conseoutive nights. 

Nevertheless, a large number of .f'ish were oounted over Bonneville Dam. 

Plate 1 and table 25 show the periods of maximum abundanoe. The total 

of 116,192 spring ohinook (through May 31), whioh was exceeded only by 

• 

the 1941 l"lm, constitutes 21.6% of the total annual count of 420.819 

chinook salmon. 

9. The number and percentages of spring chinook salmon which 

ascended each fish ladder by two-week periods are shown in table 32. 

In April, 58% of these chinook ascended the Bradford Island fish ladder. 

In May. with a larger run of fish, 54% used this ladder. The shifts 

from one ladder to another are srown on plate 2. Chinook crossing the 

Washington shore counting board are shown in photo 1 • 

. 10. The observed mortality of spring chinook salmon below the dam 

was much less than that of 1951. As upriver dams regulate the quantity 

of river flow and less water is discharged through the spillway at 

Bonneville Dam, less exposure and fewer chances of injury will result. 

-3-
Fall Chinook Salmon 

11. The fall chinook run did not reach Bonneville Dam until about 

August 20, but increased rapidly thereafter until it reached a peak of 

17,322 on September 4. See tables 24 and 32, and plates 1, 2 and 6. 

Comparatively rew fall chinook were observed by the end of September. 

Chinook Jacks or Grilse 

12. Chinook salmon, approximately 16 inches in length, are considered and tallied as jack salmon or grilse. During 1952, about 8% of 

the total chinook salmon were jacks of this size. T~e counts of these 

precocious jack salmon are included in the totals shown in table 26. 

The number of chinook jack salmon counted during 1952 in eaoh f'ish 

ladder is shown by months in table 33. 

Bl ueback Salmon 

13. The majority of' these f'ish ascended Bonneville Dam. in June,. 

A record-breaking peak was reached on Jtme 24 (the earliest peak date on 

record) when 19,571 blueback were counted. See table 24. The count 

declined to 5,417 f'ish per day by the end of' Jtme. Heretof'ore, the 

greatest number of' blueback were expeoted to reach Bonneville by July 4. 

In 1952, there were 136,939 counted in Jtme and 47,188 in July. The 

total count of' 184,645 blueback was the largest on reoord. See table 27 

and plates 3 and 7. 

14. Blueback ascended the f'ish ladders as late as October and 

November. Biologi.sts question the origin of this race of late bluebaok 

-4-
and believe that the eggs may have been brought in from British Columbia 

or northern Washington. Some of these musua1 blueback, fO\m.d during 

operation of the powerhouse fish lock, had poorly developed gonads. 

Sil ver Salmon 

15. Silver salmon usually ascend Bonneville Dam during the loonths 

of August and September. The 1952 count of 7,768 is somewhat below 

average. It is believed that th:is species needs management and hatchery 

aid to increase the rtm in the Columbia River. See table 28 and plates 

4 and 8. 

Chum Salmon 

16. This speCies is more abtmdant in the lower tributaries of the 

Columbia River and spawning migration usually occurs in October or 

No vEIII.ber. Only 1,505 chum salmon were counted in the fish ladders at 

Bonneville Dam in 1952 Which total is slightly below the 15-year average 

of 1,685. See table 29 and plate 4. As in 1950 and 1951, the annual 

cotmt was discontinued on November 29 while significant numbers of chum. 

salmon were still moving upstream. 

Humpback Salmon 

17. Nine humpbaok salmon passed the dam via the Bradford Island 

fish ladder during the months of August and SeptElllber. See tables 15 

and 17. 

-5-
Steel head Trout . 

18. An \Dlexpeoted and record-bree.ldug number ot steelhead trout 

appeared at Bonneville 'Dam during 1952. See table 30. The total ot 

260.990 exoeeds the previous high count (185,161 in 1940) by almost 

16,000. Stee1head appear during every month ot the counting season as 

is shown. on plates 5 and 9. There are t'WO periods ot abundance, the 

tirst and greater pe8.k in July, the second in September - concurrent 

wi th the tall chinook r\Dl. On July 28, the date ot greatest abundance 

tor the year, 8,920 steelhead trout were counted. See table 24. 

19. The Washington Department ot Game desired additional breeding 

stook trom the early runs ot stee1head as in 1951, but the trapping 

tacility used last year had been discontinued. 

Yearly Percentae;e ot Salmonids Counted over each Fish Ladder 

20. The number and percentage ot various species ot tish passing 

to the torebay via each ladder are sho1llD. in tables 32 to 31, inclusive. 

Table 38 shows the yearly peroentage use ot fish ladders by all salmonid 

species tor the years 1946 to 1952. inolusive. Table 32 shows the semimonthly oounts and percent ot ohinook salmon which ascended eaoh tish 

ladder. In 1952, approximately 62.5% ascended the Bradford Island 

ladder and 37.5% asoended the Washington shore ladder. It was observed 

that even when all spillway gates 'Were closed, appro:rlma.tely 25 to 35% 

ot the salmon ascended the Washington shore ladder. See plate 2. The 

shirt in tlow trom the spillway channel to· the powerhouse, as the seasou 

advanoes, has been disoussed in previous reports. 

-6 .. 
21. During the period in August and September when the submergedoritioe investigation was oonduoted (see paragraph 82), it was possible 

to make an estimate of the number ot fish whioh asoended each branc~ of 

the Bradford Island fish ladder. The number of fish oOlBlted at the·. 

torebay OOlBlting station oovers the total fish movement in both branohes 

(A and B) of thi s ladder. By subtraoting the number ot fish oOlBlted at 

Weir 47 counting station in the powerhouse or "A" branoh of this ladder 

from the total oounted in the torebay, a fair estimate of ~~e number of 

fish whioh asoended the spillway or "B" branoh was determined. During 

the fall run of ohinooks, about 17 to 20% asoended the "B" branoh and 

80 to 83% asoended the "A" branch. 

Comparison of' Return Run Cyoles of' Salmonid COlBlts - 1938-1952 

22. Comparisons of the COlmts f'or parent years with returns 4 and 

5 years later are sho1llD. f'or spring, summer and f'all ohinook, and for the 

total run of' ohinooks in tables 39 to 46, inolusive. Similar comparisms 

for the 4-year cyole of blueback, chum salmon and steelheads are shown 

in tables 47 to 49, inclusive. Comparison of' runs of' silver salmon, 

based on a 3-year cycle, is shown on table 50. The trend of counts of 

chinook, bluebaok and silver salmon, and steelhead'trout are shown on 

plates 10 to 18, inolusive. Although these tables and graphs indioate 

the population trends of these speoies at Bonneville Dam, they mayor 

may not be indioati ve of the total abundanoe of' these f'ish in Columbia 

River.

Miscellaneous Speoies 

Shad 

23. During the 1952 run, 3,131 shad were tallied at the oounting 

stations. This is the seoond lowest count at Bonneville Dam. 

See tables 51 and 52. 

24. No shad mortality was observed in the Bonne'Ville fish ladders 

in 1952. Again, as in earlier years, some shad tended to sohool in the 

ladders and oriented do'Wl1stream against the hydraulic rollback of 

ourrent from the weir next downstream. ThtU appeared to make very little 

effort, if any, to go on upstre~. Four late shad were counted in the 

Washington shore fish ladder in September. 

25. Special studies on shad at Bonne'Ville Dam by the U. S. Fish 

and Wildlife Service point out a relationship between river flow, water 

temperature and shad movement. Plate 19 shows the movements of shad in 

1952 in carLparison with the decline in flow and the increase in water 

tanperature. 

26. Commercial fishermen are taking an inoreased interest in this 

species with considerable activity in the Skamania and Multnomah Falls 

region (six to ten miles below Bonnen 11e Dam). There are several shad 

roe prooessing stations where the eggs are ranoved from the female shad 

prior to oannin~ the eggs and icing them for shipment to market. In 

these processing plants, many thousands of shad are examined and abnormalities noted. During the 1952 shad run, a perfectly-preserved spec imen of a her.maphroditic shad (A1osa sapidissima) was turned over to the 

resident biologist at Bonneville Dam. The male portion of the gonads 

-8-
_s ripe. Some idea of the gonadal arrangement is shown in photo 2. 

Smelt 

27. A small migration 0 f smelt (Eulachon) reached Beacon Rock on 

April 9, but none were reported at Tanner Creek or at Bonneville Dam. 

Lamprey 

28. Only 26,203 lampreys cros sed the fi Bh-counting boards; thi s is 

the smallest number tallied since the Bonneville Dam fishways were 

placed in operation. See tables 53 and 54. There were a few periods of 

abundance, but at no time were large numbers of these lamprey seen inohing their vay upstream. Commercial sturgeon fishermen, part~cu1ar1y 

those above the dam, are disturbed over the disappearanoe of this 

species. They attribute the catches of emaciated sturgeon to the 1aok 

of these "eels." 

Sturgeon 

29. Only 21 sturgeon were oounted passing over the dam., 10 of 

~ch were raised in the fish looks. See table 55. A number of ripe 

male sturgeon, 9 or 10 years old (determined by the ring count of the 

peotora1 fin rays) were examined. Sturgeon fishermen reported a meager 

harvest and a large proportion of the sturgeon were emaciated. 

30. A sizeable sturgeon, weighing about 200 to 300 pound~, became 

fouled under Gate 18, which 1II8.S opened approximately 4 inches. Threefourths ot the anterior end of the sturgeon had somehow passed under 

the gate but the size of the fish prevented complete passage. This 

fish may have been seeking a downstream route, or it may have been one 

tha t was killed during upstream. COllS truction where blasting was known 
to have killed large numbers of sturgeon. 

:U. Sinoe 1947" upon the reconunendation of Jean-Paul Cuerrier" 

Chief Limnologist, Canadian Wildlife Service" Ottawa" Canada" the 

pectoral fin rays have been used in the study and age determination of 

sturgeon at Bonneville Dam. Al though the validity of thi"s method is not 

completely accepted by all biologists of the Northwest, it may yet be 

proved that the rings which appear on the cross sections of the various 

bones of sturgeon are annuli. Photo 3 shows the best pectoral ray cross 

section taken on the river and photo 4 ShOWB a cross section of a bone 

from the tube-like mouth or "lips" of the 600-pound female sturgeon 

killed by blasting at The Dalles Dam in 1952. A number of fisher,y 

students agreed that the age of tht s 600-p0lmd female sturgeon was 40 to 

42 years. Photographs 5 and 6 also show information on sturgeon. 

other Miscellaneous Species 

32. The total count in 1952 for fifteen species of lesser importance passing upstream was only 170" 175 fish. The total counts for these 

species were 224,,804 and 236,,038 in 1950 and 1951" respectively. See 

tables 1 and 31. 

Activities and Observations 

Powerhouse Fish Lock 

33. Only the powerhouse fish lock was used an appreciable amount 

of time during 1952. While the auxiliary water conduit experiment was 

in progress in October and November, and during the ensuing repairs of 

the fish ladder" the powerhouse fish lock was used to lift fish from the 

powerhouse channel to the forebay. During this period a number of 

-10-
unusual migrant bluebaoks were observed. 

Bradford Island Fish Look 

34. This lock, at the south end of the spillway, was thoroughly 

overhauled during the fall of 1952. All metal parts were oleaned and 

pdnted. Lubrioation lines were run to all main valve artioulation 

joints. The upstream telesoopio barrier was reconstructed of metal 

l-inoh screening with channel iron framework. This facility was used to 

demonstrate certain hydraulio features of the auxiliary water supply 

system for The Dalles Dam fishways. 

Powerhouse and Bradford Island Auxil iag Water Soreens 

35. Eaoh year, partioularly during the £lood season, fingerling 

losses are noted on the powerhouse a.nd Bradford Island stationary 

auxiliary water soreens. During this period of high water, the aocumulation of large quantities of fine, fibrous, wa.terborne debris malces it 

virtually impossible to keep the soreens olean. Certain soreens become 

fouled first, foroing all auxiliary water through the unfouled screens. 

The inoreased velocity of water thro~h the reduoed area impinges ma:ny 

small fish against the soreens where they die. Each year, 30 to 40 

million or more of these small salmon are released from the 9 or 10 

hatcheries above Bonneville Dam. Sometimes 10 million fingerling are 

released in a week and these releases are augmented by an unknown number 

of w.J.ld £ish. Conoentrated numbers of small salmon appear at the dam in 

February, March and April. Many fingerling migrate downstream during tlB 

ranalnder of the spring and summer months. During the latter part of 

April 1952, numerous smaller fish were plastered against the powerhouse 

-11-
and Bradford Island a~liary water soreens. See photographs 7 and 8. 

To protect YO'lmf; salmon. the now of auxiliary _ter through the screens 

is reduoed 'When large numbers of small fish are present in the riVer. 

Reduotion of the flow of auxiliary _ter lessens the effioienoy of the 

powerhouse oolleotion system and Bradford Island fishway for upstream 

migrants. 

36. An experiment _8 oondmted in Ootober to determine the effeots 

on small salmon in passing through the powerhouse auxiliary _ter oonduit. 

(See paragraph 77.) 

Fish-oounting Sohedule - 1952 

37. Jan. 1 - Feb. 29 - No OO'lmting performed. Fish were free to 

pass upstream through the open oounting 

gates. 

Mar. 1 - Mar. 27 - Counters on duty for 8 hours daily (one at 

eaoh station). 

Mar. 28 - Sep_ 30 - Counters on duty for two 8-hour shifts, 

countin~ 16 hours daily. 

Oct. 1 - Nov. 29 - Counters on duty for 8 hours daily (one at 

eaoh station). 

Nov. 30 - Dec. 31 - Fish-oounting disoontinued. Stations were 

left open and fish were free to pass upstream thl"ough the open OOtmting gates. 

Forebay and Tail_ter Levels 

38. In early April, prior to the spring run-off, the stop logs 

were removed from the spillway. As in previous years, the f'orebay level 

-12-
was raised during the fall low water period (between October 11 and 13 to 

elevation 78) to produce more power. To do so. stop logs. 5 feet high, I 

were placed above the spill~ gates. 

39. During ponding periods. at night and early morning, before the 

power load is regained, little water is discharged through the powerhouse, therefor~, tail water levels fluctuate and sometimes drop to low 

levels. In the fall of 1952, an aoute water shortage developed. Consequently, in the ensuing periods of ponding, the diurnal tailwater fiuotuations were even more pronounced than in 1951 and on a number of 

oooasions the powerhouse tanwater level fell to 6 leet above mean sea 

level. In order to preserve a certain navigable river channel depth, 

the tailwater level was not permitted to fall below this lsvel. 

40. The powerhouse, spillway ani tailwater levels during 1952 are 

shown on plates 20 and 21. The daily river discharges with water 

temperatures and turbidity readings are shown on plate 22. 

Fishway Repairs and Overhaul 

41. In January, repairs to the Washington shore fish ladder and 

entranoeway oontinued despite a period of snow and freezing weather. 

This ladder \\'B.S rewatered on February 15-

42. The north Washington fish lock pit was emptied and inspected 

in February 1952 for the first time si. nee installation. A pump sump was 

later chipped out of the bottom of this pit. Myriads of small living 

fish, including shiners, suckers, squawi'ish. ohubs and cottids, and 

several dark chinook and lively steelhead, were found in the water 
leaking past the downstream unwatering or emergency gate in the fish lock 

drain tunnel and in the contiguous filling tunnel. 

43. Traction chains were replaced in February on Sections 1 and 5 

of the Washington shore auxiliary water screens. 

44. The task of bolting stop logs together was continued with the 

intention to conserve time and manpower when neoessary to handle these 

stop logs preparatory to overhaul of a fish faoility. 

45. Each year, as the forebay is raised during flood periods, the 

weirs above Weir 68 (elevation 68) in each fish ladder must be ~aised 

progressively in order to permit the fish to swim to the higher forebay 

elevation. This is done by plaoing 12-inoh stop logs in the stop log 

slots at each weir looation. After the flood season, these stop logs 

are removed and stored in the conorete walkways at each weir looation. 

Another and safer method of storage is baing tried out at one location 

by welding steel ohannels in a vertioal position to the upstr~ side of 

the stop log slot pillars, as illustrated in photo 9. 

46. In the past, oooling water strainers have S)metimes become 

plugged with small fish. During the overhaul of each unit, inlet pipes 

which formerly opened into a corner were extended several feet into the 

scroll oase. This remedy appears to be suocessful in preventing fingerlings from entering the strainers. 

47. In August, an effort was made to ranove by dredging the silt 

and debris which had oollected in the pocket between the navigation lock 

wall and the powerhouse auxiliary water screens, but it could not all be 

removed. Construction of a trash rack and stop log slots is planned 

-14-
• 

:J 

'Which will extend south from the powerhouse office wall to the navigation 

lock wall. This trash rack will prevent entry of heavy debris. The use 

of stop logs will permit periodic cleaning of this area. 

48. A suction dredge was used on September 16, 17 and 18 to remove 

silt from the exit region of the Bradford Island fish-ladder • 

49. Following the fingerling release experiments in the auxiliary 

water oonduit during October and Novamber, the "B" branch of the Bradford 

Island ladder was drained to permit reconstruction of the auxiliary water 

diffusor elements in diffusion chambers 5, 6 and 7. The vertical bafnes 

in the diffusion chambers wh:i. ch had been "tx> rn from their anchors were 

refastened or replaced. Also, the damaged uppermost timber diffusor 

gratings were replaced. 

50. A l4-inch pipe line was installed to facilitate draining water 

from the powerhouse fish collection systam and auxiliary _ter conduit 

(which lies below tailwater level), into the pump sumps Where it could 

be pumped into the tailrace. 

51. One section of the powerhouse fish collection system at Units 1 

and 2 was pumped dry, cleaned and overhauled in the fall of 1952. The 

vertical timber difi'usor bafnes in this region were intact and replacement was unnecessary. However, the wooden diffusor gratings at elevatkn 

minus 2 feet were 'WOrn and therefore were replaced. 

52. Access walkways were installed \mder the plus 60 deck fishway 

bridges over the Washington shore and Bradford Island fishway entrances. \ 

These walkways permit access and servi,cing of the tw) auxiliary water 

val ves located under each bridge.

weather data at Bonneville Dam in 1952. 

Investigations and Experiments 

Biological Notes 

54. In February, salmon, sturgeon, lampreys and other fish were 

discovered in the cooling water pl.Dllp sump at the north cd of the powerhouse men, on several occasions, the pl.Dllp screens in the generator cooling water pl.Dllp sump became fouled. At one time, one of the pump screens 

was totmd to be completely covered with partially decomposed lampreys, 

10 to 12 inches long. In order to reach this point, the tish descended 

to elevation minus 63 in the powerhouse tailrace, then entered a 

3 x 6-toot hole and penetrated a maze ot concrete cells and small openings. After the pumps were cleaned, a diver covered this hole with a 

specially-designed grating. 

55. Myriads of clams died on the mudflats above the dam when the 

tor sbay was lowered during July 10 - 12. 

56. Inquiry was made of fishermen to learn if any appreciable 

number ot dead salmon were present in the ri var below the dam. Some dead 

fish are generally found i..1 the spring, summer and fall. Only a few were 

observed in 1952 ot whioh none were tOWld with internal trauma. as noted 

in previous examinations. 

57. As the summer advanced, and river water levels tell, the water 

in Hamilton Island Slough, about one to two miles below Bonneville Dam, 

-16-

c~ 
evapoJ;"a.ted or dra.ined into the gra.vel. As usual more than 200 sturgeon 

and m&n.y' shad were f'o\Uld dea.d; other species suf'f'ered less. 

r 

58. On two sepa.ra.te occa.sions a f'ishway operator observed otters 

(Lutra) in one of' the Bonneville f'ish passes during the latter part of' 

December. T1D la.rge ottem were first seen pla.ying and f'eeding on or from 

a wooden float inside of' the powerhouse f'ish collection system. Subsequently ~ one small and two 1a.rge otters were Been on the float from which 

they were diving, bringing up and f'eeding on scra.p f'ish. When 'WOrman 

returned to duty, following the long holiday week end, these a.quatio 

mammals had disappeared. 

U. S. Fish and Wildlife Service Aotivities 

59. The U. S. Fish and Wildlife Service operated four downstream 

migrant bypass traps at Bonneville Dam. during 1952. By a.na.lyzing the 

scales taken from a sample of each oatoh, the age a.t time of migration 

1I&S ~8tab1ished. A tabulation of' bypass trap catches by months 1'01101'1'8:

60. It should be realized that these data do not give the complete 

picture of downstream. migration. During high .. ter in JlBle and July, the 

bypass traps are much less effective in sampling the migration. This is 

due to the interference of depris, the relatively smaller amount of total 

river flow being fished, and the great flow of water down the spillway 

channel. During the periods of most ablBldant oatohes, hourly cOlBlts were 

recorded in an attempt to determine the pattern of fingerling migration 

over a 24-h.our period. In order to verify the results of the oounts, 

this study will be centinued next year. 

61. The special trap designed ~e recever salmon fingerlings from 

the lower end of a draft tube was slightly modified to eliminate "plastering" .of fish en the entrance funnel (screen portion .of f'lmnel was replaced 

with sheet metal). This modification eliminated "plastering" of fish, 

but also reduced the volume .of water strained per unit of time to such an 

extent that in four tests, each involving abeut 4,000 fingerling chinoeks 

introduced into the upper end of the draft tube, only one fingerling was 

recevered in each .of the first three tests and nene in the last. All 

three ot these tish appeared to be in goed conditien and no dead .or 

injured fish were observed in the upwelling tailwater near the trap. In 

order to strain more water and recover more fingerlings per unit of 

operating time, it is planned to again modify the funnel portion of the 

special trapping device and to resume fishing. 

62~ During the peried of upstream. migration of adult salmon, obser-

"If&tions were made et dead fish along the Washington shore from the spillway dam te Garrisen Eddy, approximabely one mile downstream, and areund 

-18-
the periphery of Hamilton Island Slough. The inlet of Hamilton Island 

Slough. is at Garrison Eddy; the outlet is about a mile downriver. Most of 

the fish observed in the river section were on shore. A few were recovored in quiet water near the litore line. 

63. Durin!'; the spring freshet (usually in May) when tailwater elevation at Bonneville Dam reaohes about 26 feet above mean sea level, the 

Columbia River overnows into Hamilton Island Slough, about one to t'WO 

miles downriver. Many fish. including salmon. steelhead trout, shad, and 

sturgeon, enter the slough. at this time and when the tailwater drops 

belaw 26 feet m.s.l. in June or July, they are trapped. As the water 

recedes in the slough, the fish eventually die, presumably due to lack of 

o~gan, disease, or high temperatures. The oauses of death have not been 

definitely established. 

64. In the case of shad, in 1952, there _s a heavy .mortality 

shortly atter the free flow of river water through Hamilton Island Slough 

was out off. Later fluctuations in shad mortality are attributed to 

shallow pockets of the slough drying up and consequent total mortality 

within these pookets. 

65. Sturgeon apparently prefer and remain in the deepest areas of 

the slough. This probability, together with the sturgeon's ability to 

endure higher temperatures and lower o~gen levels in the water than shad 

oan endure, enables the sturr;eon to survive longer. 

66. Comparatively few salmon are present in Hamilton Island Slough 

during adverse oonditions, henoe their low mortality. All dead fish were 

"\ 

marked at time of observation to prevent later duplication of counts.

Bonneville Fishe:z Studies, 

67. In order to improve the efficienoy of the opera cion of 

Bonneville fish:wa¥s, numerous studies are mder _y, some of Yilioh have 

been discussed in previous reports. Several of these are continuing 

investigations such as studies of the babi ts of fingerlings, the effects 

of various spillway discharges, and oorrelation of weather data and 

other physioal phenom.ena. with the movements of fish. 

Special Fishery Investigations 

Fingerlin,-Salmon Pressure Release Experiments 

68. These experiments were conducted in cooperation with the U. S. 

Fish' and Wildlife Servioe for the purpose of endeavoring to obtain 

dependable data on the effects of hydrostatic pressure changes on fineerlings in their passage from. various depths in the foreba.y pool to beneath 

the spillway gates and into atmospherio pressureabelow a dam. The tests 

were planned specifioally to determine the damage to fillgerlings in passing under the spillway gates proposed for The Dall es Dam. The effect of 

rapid pressure change on fingerling salmon. was reproduoed and observed in , 

a series of tests at the Bonneville Hydraulio Laboratory. 

-20-
69. The first test ohamber was a steel tank, approximately 3 feet 

long, 12 inohes in diameter and fitted with olear plastio ends for visual 

observation. For introducing water and the test fish, an aocess port was 

provided at the top of the chamber; removal of the test fish and .. ter 

was accomplished through a 4-inch gate valve attaohed to the bottom of 

the chamber. To provide the sudden pressure release required, a. 'tluickacting valve was placed at the end of the standpipe to which the air 

supply line was attached. Bourdon-t,ype pressure gages, registering 

p.s.i. above atmospheric pressure, were oonnected to the test chamber. 

See photo 10. The two other test ohambers were furnished by the U. S. 

Fish and Wildlife Servioe 'Which had been used by its Seattle Laboratory 

on experiments wi. th fingerlings. One was a clear plastic tube (Photo 11) 

which had a diameter of 4 inohes and was approximately 5 feet long. Fish 

were introduoed and removed throtgh a removable end plate. The other 

test chamber was a 4-liter glass distilling flaSk. See photo 12. The 

fingerling were introduoed through the top which was closed wi. th a 

rubber stopper. The three test ohambers were oonnected to a 3/4-inch 

drain line and to a 2-inch supply line in which pressure was maintained . by a high-head pump and adjusted by a bypass valve. Valves were provided tor individual or simultaneous operation ot the test apparatus. 

70. The tish used in the tests were fingerling ohinook salmon, 

average length 52 mm., Whioh were obtained from the U. S. Spring Creek 

Hatohery at Underwood, Washington, and the Oregon State Fish Hatchery at 

BQnneville, Oregon. 

·-21-
71. With one exception where water 'was obtained from the State 

hatohery supply, the domestio water supply at Bonneville Dam was used 

during the tests. 

72. In oonduoting individual tests, the fingerling salmon and water 

were introduoed, the aooess port was olosed and oompressed air was 

supplied to the ohamber as rEquired for the test. At the end of the test 

rtm, the air supply was out off and the q1.dok-aoting valve _s opened 

, 

simultaneously. The fish were then flushed into a oontainer. Sub stantia1ly the same prooedure was used in oonduoting test runs in eaoh of the 

three test ohambers. 

73. The average test releases were from 17 p.s.i. (39 feet of pressure head) to atmospherio pressure in 0.56 seoonds, wi. th individual 

releases varying from p.16 to 1.28 seoonds. The test releases ware approximately at the rate a fingerling would pass from the high pressure 

zone upstream from the spillway to a tmospherio pressure below the gate 

lip. The actual osoillograph reoord of the pressures in one run are 

shown on plate 25. 

74. In most oases, a similar group of' fish was subjected to the 

same handling as the test group exoept for the pressure applioation, and 

these oanprised the "oont!"?l group" for oomparison purposes. The fish 

used in these experiments were retumed to the hatchery pools after eaoh 

test where they were held in separate oontainers for a la-day period. 

75. After numerous tests, it was the opinion of observers that the 

fingerlings while under pressure, without head spaoe of air, did not aot 

naturally evan after a 3-hour test pariod. However. the surviving 

-22-
fingerlings. after being subjected to pressure and the sudden release of 

pressure. appeared to be normal when returned to atmospherio pressure. 

Only by providing head space of air above the fish in the laboratory 

pressure cylinders did they act naturally \.Ulder the high pressures. 

76. Within the limited scope of the study. the test results did not 

indicate that an exceedingly rapid release of pressure is necessarily 

detrimental to fingerling salmon Which have become accustomed to pressure. 

It is recognized that in any future tests. further effort should be made 

to detennine the time necessary to accustom fish to pr essure in the 

laboratory and to learn the process whereby fin~erling salmon become 

accustomed to varying pressures in nature. 

Condui t Experiment 

77. During October an experiment was conducted in order to learn 

llIOre about the pressure and aotual conditions in the auxiliary water 

supply conduits under normal operating oonditions and the results when 

fingerling salmon were inadvertently or experimentally released into'such 

conduits. 

78. Plans for this experiment were formulated in 1949 to learn 

whether salmon. enroute to the ocean. could safely pass through the 

various fishway auxiliary water supply systems at Bonneville Dam. Fish 

are normally eXCluded from these areas by screens. However. the question 

of size of filter mesh and other oonsiderations brought about the initiation of the experiment in 1952. The plan was to release fingerlin~ 

salmon of any available size into the 7-foot square Bradford Island 

powerhouse auxiliary water oondui t at the forebay. and capture the fish 

-23-
in the fishway near tailwater after passage through this oonorete tube 

and the maze of baffles whioh were designed. to remove the energy from 

the water. 

79. Near the point of release from pressure. a Bourdon-type pressure gauge was placed on radial gate valve No. 8 which regulates _ter 

from the Bradford Island powerhouse auxiliary supply conduit into the 

powerhouse colleotion systan 1ilen water is desired from this source. The 

auxiliary water conduit parallels the fish ladder. and introduces extra 

water into the ladder normally below tailwater level thmugh ten secondary V&+ves and diffusion chambers. 

80. In the experiment. fish subj ected. to pressures of 22-26 p.s.i. 

suffered an appreciable percentage of mortalit.y When experimentally introduced into the auxiliary water supply condui. t -from 1Ih ich they had to pass 

, through three different baffles or water diffusors before being captured 

on an inclined plane trap. 

81. A1't:;er these experiments were completed with 11 ve fingerlings. 

it was found that the normal operating pressures in the auxiliary water 

conduit were oonsiderably less than those which resulted-in excessive 

mortality. Therefore. in the light of these new developments. the whole 

problem is undergoing further examination. 

Submerged-orifice Research 

82. The purpose of this investigation was to determine the relative 

efficiency of sUbmerged-orifioe and overflow-weir entranoes into a powerhouse fish-oollection system and to provide information for us e in design. 

construotion. and operation of fi. sh facilities. 

-24-
83. The scope of the investigation and st~ in 1952 was limited to 

comparison of the submerged-orifice entranoe with overflow-weir entranoe 

into the powerhouse colleotion system, using the existing sizes and 

shapes of entranoes under flow and tailwater conditions that prevailed 

during August 12 to September ,27, the period of the investigation. 

84. The plan of 8Jq)eriment adopted for the 1952 observations 'was 

to alternate between submerged-orifice and overflo'W'-weir entranoes, with 

eaoh type of entry in use fb r three oonseoutive days and an. intervening 

day for change-over. 

85. The powerhouse branoh and the spillway branch of the Bradford 

Island fish ladder lead into one oounting station'located in the forebay. 

In order to obtain a record for this investigation of the adult fish 

enterin~ the powerhouse branch, it was necessary to construct an additional counting station at Weir 47 in that branoh. See drawing T-8-15 

and photo 13. To attain suitable hydraulio oonditions at Weir 47, weircrest levels were raised tEll weirs below this oounting station from the 

normal 12 inohes to 15 inahes in order to gain 30 inohes of additional 

elevation re:Iuired at Weir 45. 

86. It was noted that in every oyole' of operation in this branoh of 

the Bradford Island fish ladder and in oomparison with the total oO\mt, 

the periods of submerged-orifioe entrance showed a higher count for 

ohinook and steelhead than those 0 f overflow weir entranoe. Whereas, in 

every oycle, the ratio of oo\mts of scrap fish at Weir 47 to the total 

oounted at the Bradford Island forebay statton was greater for the overflow-weir entranoe than for the submerged-orifioe entranoe. 

I. 
87. An underwater observation cilamber was lowered into the powerhouse oollection system. ohannel to observe the fish as they entered the 

submerged orifioes. Duro lng- me period of approximately 40 minutes, when 

oonditions were most favorable, 60 chinook were OO'lmted as they entered 

one orifice. None lei't durine; that period. 

88. It was demonstrated that mder the oondi tions which prevailed, 

wi th fluotuating tailwater levels and the difficulty in rapidly adjusting 

the entranoe weirs, the su'tmerged-orifioe entranoes were distinotly more 

effioient than the overflow-weir entranoes_ This oonolusion relates to 

the passage of salmonids for whioh the fishways were primarily intended. 

89. This finding oannot be interpreted as a valid oomparison of the 

tyro types of entranoes tmder more favorable operating oonditions. In 

faot, it is possible that the lesser effioienoy of the overflow-weir 

Erltranoe may have been due entirely to failure to maintain the ideal relation between weir-orest elevation and tailwater elevation. On the 

other hand, there is nothing to indioate that the overflow-weir 'WOuld 

be preferable it, it were possible and eoonomioal to always maintain the 

overflow-weir in perfeot relation to tailwater elevation. 

90. Due to the faot that a oonsiderable part of the 1952 investigation 1I8.S oonducted during a period of widely fluctuating tailwater oonditions, there was 11 ttle opportunity for oomparison ot varied sizes and 

shapes of subme~ged-orifioe entranoes under varied water velooities. 

91. It was recommended that the study be oontinued in another 

season in order to take ad.vantage of less variable tailwater levels during higher water levels) to oompare submerged-orifioe entranoes at varied 

-26-
depths of' submergence, of varied size and with varied water velocities, 

end to consider altering the schedule of operation to eliminate changeover days with the two test conditions immediately following each other 

(which 'WOuld require the changing of entrances at night mile upstream 

migrant fish are inactive). 

Balloon Experiments 

92. These e~eriments were conducted to develop a method of retrieving small salmon f'or determination of' the condition and percent of survival after passing throl€h the powerhouse turbines. 

93. In two series of tests in 1952, snaIl salmon were sent through 

the powerhouse turbines and retrieved minutes later in the tailrace. All 

fish that were retrieved immediately after the first experiment survived 

passage through the powerhouse. All fish retrieved after the second 

experiment lived and were released 48 hours after the experiment. 

94. Future experiments will be conducted with fish whioh have been 

subjeoted to pressure for a long enough period of' time to aooustom them 

to the pressure and with fish: Yhioh are subjected only to atmospherio 

pressures. 

95. Earlier laboratory experiments had proved that fish would survive for hours inside a muslin bag in quiet water. For these field 

. experiments, small fish (about 95 millimeters long) were plaoed in 

gossamer fabrio bags (measuring 6x8 inches or 6x10 inohes) to whioh were 

attached a round, orange-colored rubber balloon capable of inflation to 

a diameter of 16 inohes, containing only water and a so luble capsule 

f'illed with oalcium or li thitun hydride. (The fish were not inside of 

-27~ 
-----_ .... 

the balloons, but in the attaohed gossamer fabric bag. Thus, the fish 

were not subjected to any chemical action.) See photo 14. By sending 

the canbination of fish, bag and balloon through a hose into the turbine 

intake tube. the fi sh had to pass through the turbines. The fish were 

subjeoted only to the hydraulio conditions of the intake tube, turbine 

blade area. draft tubes and taUraoe. 

96. In these early tests, only one or two fish were plaoed in each 

gossamer container. However,' with better faoili ties, one hlmdred or 

more might be sent through the hazardous area at one time. 

97. The fish were flushed down a hose (photo 15) ud after a delay 

of a few minutes, the water inside of the balloon ~issolved the gelatine 

capsule and reacted 'Wi. th the lithium or caloium hydride to produce 

hydrogen gas Which innated the balloon. The gaseous buoyanoe of the 

balloons brought them to the surface in the tailraoe (after passing 

through the turbines) where they were readily seen by waiting boatmen. 

These fish were retrieved and held in an observation tank for a period of
