This report i8 an annual pg,lication which presents pertinent summary 

statistios on the migration of fish at Bonneul1e Dam. It i& limited. 

therefore. to the passage of fish. the operation of fish facilities. and 

other aoti'Vi ties conneoted with fish migration at Bonnen lIe Dam. No 

attempt is made to correlate these data with cODmeroial statistics or 

other available data on the fishery resource. 

This report is design.ecl to sene as a convenient reference for summary 

i:Dtormation and a chronologic guide in the study of the migration ot fish 

at Bonneulle Dam. 

The statistios shown are for the oalendar year 1953. Summaries of 

fish counts by speoies are shown herein to provide a continuity of comparable data for each calendar year from 1938 to 1953. inclusive. Brief 

deSCriptions of investigations and experiments performed during the year.

ANNUAL REPORT ON THE PASSAGE OF FI SH 

BONNEVI LLE DAM 

CALENDAR YEAR 1953 

Summary 

1. The 1953 oounts of chinook and steelhead fell below the reoord 

oounts ot 1952, but bluebaok, silver and ohum counts exoeeded the 1952 

reoord. The total salmonld oount tor 1953 was slightly less than the 1952 

total. However, the 1953 total ot salmonid is 11811 above the 16-year 

average. 

2. The total of all speoies counted during 1953 was 1,138,628 

which exceeded all previous years since fish-counting was initiated at 

Bonneville Dam. The 16-year average, 1938-1953, inclusive, ot 945,009 is 

considerably above the preceding 15-jsar average of 932,094. 

3. The salmonid count for 1953 or 806,364 comprised 332,419 chinook, 

223,914 steelhead, 235,215 blueback, 13,018 silver, 1,128 chum and 10 

humpback. The total or 332,264 miscellaneous tish was slightly below the 

16-year average. 

4. The 1953 spring run of chinooks exceeded all previous years, but 

the fall run fell to less than halt the 16-year average. See table 26. 

Spring and 8U1111118r runs of chinook and blueback appear to be responding 

tavorably to management practices and the counts ot these tish at 

Bonneville Dam are increasing. .Annual totals of all ti sh which asoended 

Bonneville Dam during the periOd 1938-1953, inolusive, appear in table 1. 

Monthly totals are listed in table 2. Daily reoords, by months, are compiled in tables 3 to 23, inclusive. Peak days of fish migration (by 

-1-
species) for the period 1938-1953. inclusive. are shown in table 24. The 

days ot maximum abundance ot fish counted over each fish ladder tor the 

same period are shown in table 25. Monthly counts of salmonid and Btaelhead trout tor the period 1938-1953. inolusive. are shown in tables 26 to 

30. inclusive. and mdscellaneous specie. oounted over the same period are 

shown in table 31. 

5. Mild weather and abundant rainfall prevailed througllOut the year 

wi th only a few days of recorded freezing weatber in Januar,-. February and 

December. A total of 99.~ inohes ot precipitation was recorded during 

1953. 30.74 inches of which was recorded in January. 

6. Fish-counting was im ti ated on March 1 and di scontinued on 

November 28. 1953. tor annual winter maintenance or fish facilities. 

During periods when no counters were on duty. at least one complete fish-

. way system was continually accessible tor the unimpaired passage of upstream migrants. 

7. The biological work conducted during 1953 consisted chiefly ot 

perfecting techniques involved under prototype experiments in sending 

adults and small fish in gossamer bags through the spillWSJ and powerhouse. 

respeoti vely. with delayed-aotion retrieving devices attached. to obtain 

more definite data on survivals. 

8. An infortlation bulletin and an operation manual in draft torm. 

describing the ti sh 1'ac11i ties at Bonnen lIe Dam. were prepared duriDg 

the year. 

-2-
Spring Chinook Salmon 

(Karch 1 - May 31) 

9. Spring chinook appeared at Bonneville Dam a month earlier than 

in 1952. The peak ot abundanoe was reached on April 22 when 12.950 

chinook were oounted. Inasmuch as the .spring run was earlier than the 

opening of the commercial fishing season (April 30 below the dam and two 

weeks later above the dam). the commercial tisher,y took relatively few 

chinook which conversely increased the count at Bonneville. A decline 

in abundance ot spring ohinook salmon ocourred after April 22. and there 

was a resurgence ot the count in early May. the reasons tor whioh have 

not been determined. Possible oorrelations may eventually be found by 

study of water conditions as shown on plates 22 and 23. Plate 1 and 

table 25 show the periods ot maximum abundance. The total of 170.287 

spring ohinook salmon (which has never been exceeded) constitutes 51.2 

percent ot the 1953 total of 332.479 ohinook salmon. See table 26. 

10. The number and percentages of spring chinook salmon which 

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

Spring chinook salmon which ascended the Bradford Islam fish ladder 

(67.85 percent) were more than double the nUIdJer oounted at the Washington 

shore tish ladder (32.15 percent). The shifts trom one ladder to another 

are shown on plate 2. Plate 10 delineates the comparison with pre"Vious 

years and the present increas~ng trend in the number of spring chinook 

which ascended Bonneville Dam. 

11. From inquiries made of tishermen. less dead fish were observed 

in the river below Bonneville Dam in 1953 than in pre"Vious years. Fishermen have previously reported that dead fish observed in the river may 

-3-
possibly be correlated with spillway discharge. While the spring chinook 

run was at its peak, only a small quantity of water was disoharged through 

the spillway gates. One possible benefit to be derived trom river regulation, as more storage dams are construoted above Bonneville, will be less 

frequent operation of the spill~ gates to discharge water during the 

heavier concentration of the spring run. Experiments, to determine the 

effeots on adult and fingerling salmon passing into the stilling basin 

below the spillway and through the powerhouse, were initiated during the 

year. 

Summer Run Chinook Salmon 

(JUDe 1 - August 15) 

12. During recent years, a resurgence at summer run chinook salmon 

has beeD noted. See plates 1 and 6 ot recent aDDual reports. ~ 

individuals of these races are large fish called "June hogs." This species 

reached the highest peak day of the year when 3.897 ware counted OD June 26. 

See table 11. In 1953, 64,857 summer chinook salmon wre tallied which is 

19,L12 fish in excess of the 16-year average. See table 26 and plate 11. 

Fall Chinook Salmon 

(August 16 - November 28) 

13. In point of beginning (August 20) and date of maximum. abundance 

(September 3), the 1953 tall run closely paralleled that of 1952 (August 21 

and September 4, respectively). The tall run reached a peak at 9.083 which 

was less than the spring run peak, and the lowest tall peak e'V8r recorded 

at this station. The 1953 count of 97,335 tall run tish was the lowest 

-4-
recorded since counting began in 1938. Also, the 1953 fall run was only 

41 percent of the 16-year average. It was a grave disappoin"bnent to commercial and sport fishermen who participated in this aoti vi ty or were 

dependent upon it. Data on the fall run are shown in tables 24, 26, 32, 

and plates 1, 2 and 6. Plate 12 graphically illustrates the decline of 

the fall fish population. Ever since fish-counting was initiated at 

Bonneville Dam, the fall runs have exceeded the spring runs of chinook 

salmon, but from plate 1 it will be noted that the 1953 spring run was 

nearly twice that of the fall run. Plate 2a graphically illustrates the 

percentage of chinook salmon which asoended each fish ladder. 

Chinook Jacks or Grilse 

14. Small male chinook salmon, apprOximately 16 inches in length, 

are considered and tallied as jack salmon or grilse. During 1953, approximately 9.69 percent of the total ohinook salmon were jacks of this size. 

The counts of these precocious male chinook are included in the totals 

shown in table 26. The number of such fish, oounted in 1953 at each 

counting station, is sho1VIl by months in table 33. In earlier years ot 

fish tallying, a noted fisheries researchsr deterDdned that there appeared 

to be some contusion in distinguishing jack salmon and the equal-sized 

blueback salmon at Bonne~lle Dam. Subsequently, acourate identifioation 

of these fish was made by use of ohecking traps. No analyses have been 

made in reoent years. The spring chinook trap under construction at the 

Washington shore fish ladder by the U. S. Fish and Wildlife Service will 

be an aid, upon completion, in further differentiation of these species. 

-5-
Blueback Salmon 

15. Al though a minor run ot blueback salmon 1I8.S expected, the 

greatest run ot record developed •. At the close ot the counting season, 

235,215 blueback salmon had been counted. This total exceeds the highest 

previous count of 184.645 in 1952. On July 5. 1953, 20,351 blueback 

ascended the tish ladders. See tables 13 and 24. This number a180 

established an all-time high daily record. However, this record ot a 

blueback run 1a probably not as great as that reported tor ODe day in 

1896 when a barge fish wheel, which was looated at the present north end 

of the spillway d~. ceased operation as the barge began to sink due to 

the weight ot the large number ot blueback captured by the revel nng wheel. 

Tables I, 2 and 27, and plates 3, 7 and 14 present pertinent blueback 

statistics. Although a contagious virus disease is reported to have 

seriously devastated hatcher,y bluebacks in reoent years, plate 14 indioates a gratifying increase in the trend of abundance ot this species. 

Sil ver Salmon 

16. .An unexpeoted and almost reoord-breaking number ot silver 

salmon appeared at Bonneville Dam during 1953. In 1941, 17,911 silver 

salmon (the highest count ot record) ascended the ti sh ladders. The 

second highest count since 1941 was recorded in 1953 when 13,018 ailver 

salmon were counted. This total exceeds the l6-year average ot 8,4.74. 

According to reports, this species haa been declimng in a number ot 

coaatal streams as _11 as in lower ColUllbia River tributaries. Data on 

silver salmon counts are shown in tables 1. 15, 28, 35, and plates 4. 8 

and 15. 

-6-
Chum Salmon 

11. A slight inorease ove~ reoent years is noted in the total or 

1.128 chum salmon counted at Bonneville Dam in 1953. This total exceeds 

the l6-year average ot 1.688 fish. See tables 1. 29. 36. aDd plates 4 abd 

15&. On May 18. 1953, 100,000 chum fingerling, apprOximately 2 inches 

long, were released trom the Little White Salmon Hatchery. About 243,000 

fingerling (advanoed try) were released trom the same hatchery on April 28, 

1948. but no inorease was noted in the returns ot 1951. However, in 1953, 

as in 1950, 1951 and 1952. tish-oounting was discontinued the end ot 

November while signiticant numbers ot chum. salmon were still mo'Ving upstream. 

Humpback Salmon 

18. Ten ot these "pi Ilk " salmon were ta1li_ed on their way to the 

torebay during 1953. See tables 1 and 2. 

Steelhead Trout 

19. The 1953 steelhead trout run ot 223,914 was somewhat less than 

the record run of 1952 (260.990). See tables 1, 24. 30. 31 and plates 5. 

9. 16. 17 and 18. ExaDdnation ot plates 16. 17 and 18 indicates an 

increase in spring and summer races and a decrease in tall runs ot steelhead trout at Bonneville Dam. Leading biologists attribute part of this 

decline in tall runs of fish to the intensi va fishery at Celilo. MaD¥ or 

the 1953 summer steelhead trout were extraordinarily large. With the 

advent of the cherry bobber. which is a new angling lure, an intensive 

-7-
and highly successful sports t1 shery tor steelheads has been developed 

below BODUenlle Dam. 

Yearly Percentage ot SalmoDids Counted Over Each Fish Ladder 

20. The number and percentage ot various species ot fish which 

ascended the torebay via each fish ladder are shown in tables 32 to 37. 

inclusi vee The yearly percentag,e use ot fish ladders by- all salmonid 

species for the years 19~ to 1953. inclusive. is shown in table 3B. The 

seml-monthly oounts and percentages ot chinook salmon which asoended each 

fish ladder are shown in table 32. In 1953. approximately- 65.72 peroent 

ascended the Bradford Island fish ladder and 34.28 percent asoended the 

Washington shore fish ladder. It was observed that even when all spillway 

gates were olosed, apprOximately 33 percent of the salmon ascended the 

Washington shore fish ladder. See plate 2,. The shift in flow from the 

spillway channel to the powerhouse. as the season advances. has been 

discussed in earlier reports. Comparisons of the percentage utilization 

of the Bradford Isla.nd and Washington shore fish ladders and of the discharges at the powerhouse and spillway. respectively, are shown in plate 2&. 

Comparison of Return Run Cycles of Salmonid Counts--193B-1953 

21. lOre knowledge of total fish population, particularly commercial 

speCies, and more reliable information on the trends of the total abundance 

of various commercial species in the Columbia River are highly desirable. 

The decimating faotors and likewise salutary management practices both 

have significant etfects on the fishery. Such information is highly 

important to wise management of this national food resouroe and to the 

-8-
fishing industry as a whole. A continuing study is being made ot \he 

trends at Bonneville Dam but this study is an incomplete analysis of the 

whole problem. The analyses ot the various speoies at Bonneville Dam are 

of value. HOwever. it should be recognized that thB,Y exclude the trend 

ot oommercial. sport or Indian fishery actiVities. A thorough analysis 

of the tactors which influenoe· the industry and the resource is important 

and neoessary. 

22. Comparison of parent year oounts at Bonneville Dam ot spring .. 

sWllller and tall chinook. with returns 4 and 5 years later. are shown in 

tables '9 to 46. inclUsive. SiDdlar comparisons at parent year counts 

for the 4~ear cycle of blueback, chum salmon and steel heads. are shown 

in tables 47 to 49. inclusive. and comparison at silver salmon rUDS. based 

on a '-year oyola. is shown in table 50. The trend at the oounts at these 

salmon1ds is shown in plates 10 to 19, inclusive. Although these tables 

and graphs indicate the population trends of salmonid species at Bonneville 

Dam. tl)ey .y or may not be indicative at 'the total abundance ot these 

species in the Columbia River. 

Miscellaneous Species 

Shad 

2,. A total ot 16.4,0 shad. the highest number sinoe 1949 to reach 

the torebay was tallied in 1953. Sae tables 31. 51 and 52. and plates 19a 

and 19d. No shad mortality was observed in the tish ladders in 1953. 

Again. as in earlier years. some shad tended to Sobool in the ladders and 

oriented themselves downstream against the ~draullc rollbaok at ourrent 

trom the weir next downstream. As usual .. they appeared to make very 

-9-
little~ettort to go on upstream through the submerged oritice portion of 

the upper e.nd.s of the fi shways until smaller surface openings were construoted for shad and other les8er speoies. These small orifioes were 

constructed in the weirs in August after whioh numerous shad and other 

lesser speotes in the ladder readily moved to the fbrebay. On plate 19d. 

the movements of shad are shown in comparison with the decline in flow and 

the increase in ri ver water tamperaturo. 

24. COllllDaroial tishing for this species appears to be increasing. 

Some commercial tisher.men catch shad during periods when the salmon-fishing 

season i8 closed. Plate 19a shows the trend ot abundance ot shad at 

Bonnevi 11e Dam. 

Smelt 

25. Smelt (or Eulaohon) at frequent intervals migrate up the river 

to Bonneville Dam and occasionally farther upstream. A large run ot smelt 

entered the Columbia River in 1953. ~ ot these smelt penetrated the 

Sandy River on April 19. the latest date in 2)+ years ot reoord. Bot since 

April 9. 1929. has the smelt run in the Columbia River been as late as in 

1953. In 1952. the smelt milled around the mouth ot the Sandy River early 

in April but did not enter the ri wr. Instead, they moved upriver to 

Beacon Rock and Warrendale. 

26. In 1953, a steady movement of smal t proceeded upstream along the 

shores ot the river. The 1953 smelt appeared at Tanner Creek and at the 

navigation look ot Bonneville Dam on April 22. Great shoals of smelt 

approached the dam. During this run. large murbers ot smelt entered the 

powerhouse f1 sh collection system, but noDe asoended the fi sh ladders. 

Ma~ entered the powerhouse fIsh lock, and a few smelt were elevated to 

-10-
the torebay. The movement into the navigation look oontinued until 

April 26. A large number ot these smelt entered the forebay via the 

navigation lock and moved as tar east as the Casoade Looks navigation 

channel Where residents ot the ci~ ot Casoade Looks dipped smelt from the 

river. None 1I8re observed at Eagle Creek or Herman Creek. above Bonneville. 

nor at Hood River. Sma 1 t were reported to have reaohed Hood River in 1945. 

~. Numerous smelt drifted downstream into the fingerling bypass 

traps. It is possib~e that lIIIUJIY of the smelt which reached the forebay 

drifted back downstream. A portion ot these smelt may have rejoined the 

drive upstream and thus gave an exaggerated impression of abundance. At 

~ rate. it appeared that several million reaohed the dam. 

28. From age readings of otoliths. it was determined that these 

smelt ware predominately 3 years old. Spawning was observed in Tanner 

Creek on April 22 and 23. The spawning smelt moved along the shores in 

the swift water to the outflow of the Tanner Creek bypass. Surprisingly. 

these fish disappeared the night of April 26. The following day. search 

was made below the dam but only one live smelt was observed. Subsequent 

events iDiioate that a large movement of sturgeon followed the smelt upstream and these sturgeon appeared tat and heav,y from feeding on smelt. 

Lamprey 

29. Approximately one-half of the 16-year average nUDi>er ot lampreys 

asoended the fish ladders at Bonneville Dam in 1953. See tables 2. 31. 53 

and 54. Lampreys were DOt 'Visible in the ladders exoept when delayed by 

submerged oritice 1I8irs. The small surface openings. or overflaw weirs. 

which were opened in August. appear to have provided a more aooeptable 

route. Aquatic biologists have learned that this species prefers to 

-11-
migrate at night, thera.fore, large nUDbers of lampreys are seldom seen in 

the fish ladders. Fewer ammccoetes are taken 9aoh year in the bypass traps 

at the dam. Observations dUrillg the past 5 years indicate that lampreys 

have been rapidly diminishing in nUl'lber. Sturgeon fisherman deplore the 

dearth of lamprey and link this oi rcumstan09 with the eJll8.cia ted cond! tion 

of sturgeon in the Columbia River. Reoognizing the seriousness of the 

situation, strong measures are needed to increase the abundance of lampreys. 

The trend of lampreys passing Bonneville Dam, with the deolim 8ime 1938, 

is shawn on plate 19b. 

30. Early in the summer of 1953, ~~e Zoology Department of the Un!-

V9rsi~ of California, Los Angeles, requested a number ot live lampreys to 

be used in neurological researoh. Experiments were conducted to learn the 

techniques neoessar,y to suocessfully transport live lampreys such a distanoe 

in warm wather. After it was determiD9d that lampreys would survive under 

oertain oonditions enroute, a number ot lampreys ware expeditiously and 

suooessfully transport"d to the UBi verst ty vi a air express. Further requests from the Un! versi ty for . shipments of lampreys W8re fulfilled and 

werg equally sucoessful. 

sturgeon 

31. Thirteen sturgoon reached the forebay in 1953, of Whioh 6 

ascanded the ladders and 7 were elevated in the fish locks. See tables 2, 

31, and 55. Of' the IDaDif bone speoimens ot sturgeon, 730 have been moum.ed 

on slides and filed for future reference. Several of these samples are of 

large Idaho sturgeon, some of which were reoei ved in 1953. 

32. Only during the smelt run wer9 sturgeon abundant in the cOJlll'lSraial fiBhery below the darn, and only at this time wre tat, prime n. sh 

captured. The Cook's drift commercial tisher,y above the dam produoed 

-12-

'I 
thousands of pounds of sturgeon in 1948. Because of changed oondi tions, 

this drift has beoome unproductive in recent years. 

33. There is DO record at present of the magnitude of the sturgeon 

harvest by anglers but the take is believed to be signifioant. In order 

to establish a uniform. system. there is a movament under oonsideration to 

prohibi t commeroial fishing for sturgeon at night, but which would permi t 

sports fishing for sturgeon during those hours. Many sportsman advooate 

that DO sturgeon lees than 36 inohes in length should be retained by 

anglers. 

other Miscellaneous Species 

34. The total count of 14 species of tish of lesser importance 

amounted to 332,264, or more than twioe the total counted in 1952. This 

total has not been exceeded since 1949. See tables 1, 2 and 31. Plate 

19c shoW'S an increasing trend in the coDbinsd oounts of misoellaneous 

speoiel, excluding shad and lampreys. 

Aotivities and Observations 

Powerhouse Fish Lock 

35. During the period that the Bradford I slam "A" Branch fi sh 

ladder was unwa.tered tor repair, tish ware lifted to the forebay by meanl 

of the powerhouse fish look. This tacili ty also serves as a cODvenient 

place to lower the powerhouse auxiliary water screens as they are washed 

with the toroe of water from a high pressure jet. See drawing T-8-l5. 

Bradford Island Fish Lock 

36. This t1 sh lock was operated only f'or damonstration purposes in 

1953. .An assembly of visitors from the Isaak: Walton League and the Oregon 

-13-
Fish Commdssion observed the efficacy of this lock on July 12 when a large 

number of ohinook salmon were lifted to forebay level. 

'Washington Fish Lock 

37. This facility was operated only at infrequent intervals. Bo 

attempt was made during 1953 to lift sturgeon or salmon -m tho forebay for 

speoial purposes with this facilit,y as in reoent years. The telescopic 

barrier was rsconstructed similarly to the Bradford Island upstream 

telescopic barrier wi tb. l-inoh metal screening. 

Powerhouse and Bradford I sland AUXiliary Wator Soroens 

38. In previous annual reports on the passage of fish over Bonneville Dam. the difficulties enoountered in the operation of the statioDary 

aUxiliary water screens and keeping them clear of fine fibrous debri s 

during flood season has been explained. Following the 1952 auxiliary 

water conduit fish mortali t,y experiment and the 1953 investigation of 

aun liary water condui t pressure conditions. it was found that by reducing 

the flow of water through the auld. liary water soreens when large DUlIi>ers 

01' small fish were migrating downstream that fingerling 10sse8 on the 

screens were materially reduoed. 

Fish-counting Schedule - 1953

40. During minimum. flow periods. stop logs, 5 teet high. were placed 

011 top ot the 50-f'00t spillway gates to raise the torebay level to an 

elevation of' approxLmately 78 t'eet above sea level. Thus. more head and 

power were produoed trom the smaller quantity of natural tlow. PoDding 

ot' water duriDg this period was continued duriDg the night hours when the 

river flaw dropped below 130,000 c.f.s. The powerhouse, spillway, forebay 

and tailwater levals tor 1953 are shown on plates 20, 21, 2la and 2lb. . 

The daily river discharge with water temperature and turbidlt, readings 

is shown 011 plate 22. 

Fishway Rep~irB and Overhaul LJ 

41. The Bradford I sland fish look was thoroughly overhauled wi th 

the exoeption ot the brail. This overhaul operation included removal, 

cleaning and painting of' all segmental and closure gatesJ also the installation ot skin plates on the upstream gates, oleaniDg aDd painting of' all 

tixed steel. and reoonstruction ot the onginal 'WOoden pickets of the 

telescopic barrier. New finger barrier counterweights, similar to those 

in the Washington fish lock, were installed in the Bradford Island fish 

lock. The drain valve (No.6) ot this lock was also completely overhauled. 

Grease lines W8re replaoed and all metal was cleaned and painted. The 

-15-
telescopic barriers of the Washington and Bradford Island arid powerhouse 

fish locks were reconstructed with metal and I-inch wire mesh. These 

repairG and overhaul extended over several weeks due to delays during 

rising tailwater Which caused tamporar,y deferral of work in the area. 

42. The diffusion chanbers. 5. 6 and 7. of the powerhouse branch of 

the Bradford Island fish ladder ware reconditioned by replacement of 

baftlea and lumber gratings. and the vertical timer batfle supports W9re 

re-anchored. All auxiliary water valves 1I8re cleaned. painted and adjusted. 

The baae of the lower sections of the unnatering stop logs (lxl2-inch 

timber) whi ch had become worn and splintered was replaced wi th new 

material. Stop logs ware bolted together into sections of two in the 

Bradford Island travelling screen pit. 

43. Following the overhaul of the No. 2 section of the- powerhouse 

collection system in late 1952 and early 1953. the No.5 section was 

pUlllped and all silt and debris removed. Sections ot the reinforced concrete diffusor beams ware removed to permit a skip and crane bucket to be 

lowered into the valve pits. All embedded steel was cleaned and painted. 

and all lumber diffusors were replaced. but it was unnecessary to replace 

the vertical 6x6-inoh timber batfles. All sluice valves. including four 

in the lock section, were inspected. One sluice valve at each ditfusor 

section was repaired. the others ~~re welded shut. These valves were 

originally operated to flush the debris and si It from the diffusor elements 

and service the diffusion ohambers. 

44. A 4-toot section was cut out of the top of the header between 

the 14~inch sluice line in the toe of the collection channel and the main 

teeder line leading to the sump pump in the north end of the po'V'rerhouse. 

-16-
The opening was covered by a grill with lx2-inch openings. In addition, 

a 14-inch gate valve was installed in the drain line. An air ooupling 

was later installed to prevent fouling of the inlet gratiIlg with bark and 

twigs. This sump pump may now be used to drain any seotion of the powerhouse fish collection ohannel. However, aUxiliary portable pumps are 

necessary when the No.1 section ot the collection system and the fish 

lock collection 8,Ystem are unwatered simultaneously. 

45. The Washin~ton and Bradtord Isler~d fish ladders ware unwatered 

to tailwater level tor annual inspeotion, adjustment ot traction chains 

and removal ot silt. Traction chains in seotions 1 and 3 or the Bradford 

Island aUXiliary ~~ter soreens and sections 3 and 4 of the Washington 

installation were replaced. Holes were drilled in the auxiliary water 

conduits of both branches of the Bradford Island ladder (A and B) and the 

powerhouse collection B,Ystem tor installation ot piezometer tubes to 

obtain pressure readings and other data necessary to determdno the amounts 

of water used in the auxiliary water supply systems. 

46. In order to provide access to the awdliary "''atar coIlduits without the neoessity of unwateriIlg the ladders, manholes were cut into the 

top of the auxiliary water conduits of the Washington shore and Bradford 

Island fish ladders and heavy steel covers placed securely over the 

manholes. 

47. Position indicators were plaoed on all gate valves of the parlerhouse fish oollection s,ystem to record the differenoe in water levels 

betrmen the tailrace and the powerhouse fish collection ohannel. 

48. Drains were installed to carry leakage from the "A" Branch 

auxiliary water conduit into the fish ladder. Broken and d8Ir!9.ged pla:nks, 

-11-
separating the powerhouse fish oolleotion system and the draft tube stop 

log slots, were replaoed. Work was im tiated on the installation of a 

level-winding, self-tensioning reel for the fi sh colleotion system 55 deck 

crane to prevent damage to the eleotric power supply line to the crane. 

49. The "B n or spillway branoh of the Bradford Island fi sh ladder 

was overhauled during the fall of 1953. A leak was discovered at the 

bottom of this ladder in diffusion chamber 24. At this point the ladder 

rests on piers and beams the foundation of which may have eroded causing 

the ladder to settle. No detinite plans havo been made tor etfecting 

repair. See drawing T-8-15. 

SO. New, heavily-creosoted stop logs of several sizes were obtained 

during the fall of 1953 for replaoement of the original equipment which 

shows considerable rot and deterioration. 

51. A differential water level recorder was installed at the powerhouse colleotion ~stem for use in submerged orifice studies to shaw at a 

glance the amount of head in the oolleotion,system. Also, tor this study, 

segmental gates were atfixed to the bottom of eaoh of the 16 closure gates 

in the powerhouse fish oollection ~stam. Special 60 c.t.s. orifioe 

. sections were bolted to the bottom of this installation. 

52. A new counting house with an eleotric hoist meohanism was 

designed tor installation at the Washington shore cO\mting station. 

53. On April 6, the forebay level was lowered and tile 5-foot stop 

logs previously plaoed on top ot the spillway gates during the low-water 

period were removed. Following the highJWater period, these stop logs 

were again placed on top of the spillway gates. 

-18-
54. Between August 4 and 6, it was neoessary to close gates 1 and 

18 in order to remove the lampreys trom the soreens across these bays. 

See photos I and 2. 

55. Following the fall run and after fish-counting was discontinued 

o 

for the winter season, divers and 1IOrkmen prepared the footings tor the 

new trash racks and stop log assembly above the powrhous9 water supply 

intake. This installation will per.mit the region of the powerhouse 

aUxiliary water screens to be drained during overhaul periods. The trash 

raoks will prevent the entry ot logs and brush into the pooket where debris 

has colleoted and substantially lessened the effectiveness of the soreens. 

56. The str~ngthening of stop log slots upstream from the Washington 

counting station was initiated late in Deoember. These stop log slots 

were originally designed for a forebay level of 12.5 feet. During low 

water periods, when power requirements exceed output, the forebay level 

is raised. In order to withstand the head at a forebay elevation ot 11.5 

feet to 78 feet, it was necessary to reinforoe the stop log slots. 

" • When the forebay was lowered on Deoember 28 and 29, the contraotors for the U. S. Fish and Wildlife Servioe took advantage of the low 

water level to begin construction of the spril'lg chinook trap and tanlcloading f'aoility at the Washington shore oounting station in order to 

complete the installation before the beginning of the 1954 spring run.

Investigations and E~eriments 

Biological Notes 

59. Numerous sturgeon were ob served leaping in the north channel on 

January 9. whioh appears to be a common ocourrenoe following a period of 

spillway discharge during this season. 0 

60. Between April 13 and. 26. an intense spring ohinook sports 

fisher<J developed a few hundred teet below the entranoe to the Washington 

fish ladder. Dozens of anglers stood elbow to elbow along the shore for 

approximately 100 yar!is. A large number ot spring chinook were taken and 

some were observed being hooked on the anglers' first cast. The unusually 

cl~ar water was oonsidered by fishermen to have materially aided their 

catch. Several injured fish were retrieved trom the water close to-the 

shore. One of these injured fish which had been beheaded was turned over 

to a biologist tor examination. When the spi11~ discharge pattern was 

changed. the spring ohinook lett the iJIll18diate vicinity of 1hat shore. 

U. S. Fish and Wildlife Servioe Aotivities 

61. A few small chinook fr,y. on which the yolk sacs were still 

visible. appeared in the inclined-plane bypass traps in the early part 

of January before a~ reported ha tcher,y releases above the dam. Except 

during periods when part ot the Washington shore and Bradford Island 

facilities were under repair and the bypass traps were inoperative. the 

four fingerling bypass traps were fished as usual throughout 1953. Atter 

identification. measuremant and remo~l of scale samples for deterDdnation of age. salmonid fish were returnad to the ri. ver below the dam. A 

tabulation of bypass trap catohes by months is as follows:

62. Hourly counts or fingerling salmon entering tile bypass traps 

were made again in 1953 to detennine the migration pattern over a 24-hour 

pariod. As in 1952, these counts '1RJre greater at da1lD and dusk. 

6,. A proposal entailing modifications to existing fingerling 

trapping devices, and a new technique for reoovering the salmon fingerlings trom the lawer end at a turbine draft tube, have been approved and 

the method ~ll be tried early in 1954. 

64. I:nf'ormntion includiDg Size, sex, degree or matur1 ty and age ot

Speoia1 Fishe;r Iuvestigations 

BonneVille Fishery Studies 

65. Numerous studies are under way, some ot 'Which have been disoussed in previous reports. Several of these are continuing investigations 

-21-
suoh as studies ot the habits of fingerlings. the effects of various 

spill~ disoharges. and correlation of weather data and other physical 

phenomena with the movements of fi she 

Submerged Orifice Research 

66. Construction of speoial orifices tor later study and installation ot a tailwater measuring device ware the only work performed in 1953 

on the submerged orifice tnvestigations initiated in the fall of 1952 

under the North Pacific Division Fisheries Engineering and Research Progr~. 

Personnel ceilings precluded the hirinc of additional amployees to continue 

these investigations during the spring run. Since it vm.s desirable to 

study phases that could not be accomplished in the remaining time. the 

investigations were deferred tor one year. 

Lamprey Experiments 

67. Before live lampreys could be transported to the Zoology Department of the Universi~ of California, Los Angeles, by air express, a 

number ot experiments were undertaken to learn the techniques required for 

the protection and Burn val ot these cyclostomes in transit. After 

several UDsuccessful experiments by various means. the following experiment proved suocessful. Three l~pr9ys were placed in a can (generally 

used for shipping tropical fish) which contained 1-1/2 inches of water, 

a quantity of ioe and sodimn amy tal. Subsequently, twenty-four lampreys 

were suooessfUlly transported in the first shipment, and several equallysuccessful Shipments followed. A detailed field report has been prepared 

on these experiments. 

-22-
Balloon Experiments 

68. Sevard experiments were conducted in 1953 in addi tion to those 

conducted in 1952 to improve the techniques necessary to retrieve small 

salmon in the tailraoe tor determination of the condition and percent of 

survival after passing through the pow'erhouse turbines. It was learned 

that by fastening a small weight (with very fragile thread) to the 

gossamer fabrio bag in which the fingerling were placed and to whioh the 

balloon was attached, fish could in this way be introduoed into the 

intake tube gate slots instead of sending 'them through a hose into the 

turbine intake tube and thence through the turbines. In one test, 90.6 

percent ot the test fish and 100 peroent ot the control group of fish 

wars recovered. 

69. In another test ot this equipment and procedures, adult carp 

were used in lieu of salmon. Attaohed to the carp were deflated, delayedaction automatically-inflated rubber balloons which together were sent 

under a spillway gate to demonstrate the efficacy of the method of 

recovery. See photo 3. 

Pressure Experiments 

70. In order to experimant with fingerlings stil jected to various 

pressure cond.itions, or subjected only 1n atmospheric pressures and . changes in pressures, a speoial prossure chamber was designed and oonstructed for use in passing pressurized fish through the powerhouse. 

71. These pressure chamber tests disclosed several difficulties 

which subsequontly were overcome by refinements in design. The pressure 

CM!nber was designed to panni t fingerling salmon to be held over night 

(in the chamber) in any depth of wat'3r and at the same time providiDg 

-23-
head space of air abova the fish in the chamber. In laboratory experiments it was found that the air spaoe was neoessary to acoustom the f'i sh 

to the pressure in the chamber. The ti sh were released by means of a trip 

line attached to the chamber. See photo 4. Additional tests will be 

conduoted before quantitative studies are undertaken. These pressure 

studies could be conducted profitably in conjunction ~th the balloon 

experiments. 

Conduit Pressure Studies 

72. Piezometer tubes were installed in all auxiliary water conduits 

and extensiva pressure and flow analyses were made of the quantities of 

water used in each fishway with different valva settings. These data 

will be included in an operation manual being prepared on the fish 

facilities at BODD8ville Dam. 

Bonnev.Ule Fisheries Information Bulletin 

73. During the lat~er part of 1953. a final draft of a comprehensi va 

information bulle"i;in was prepared. for future distribution. on the 

Bonneville Dam fishways. This bulletin will cover peri.i.nent information 

on oonstruction and subsequent operating experience. 

BonneVille Fishways Operation Manual 

74. A tinal draft of a manual is in process of preparation which 

describes the operational procedures of the Bonneville fish facilities.
