﻿REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  LXIX 
  

  

  With 
  the 
  view 
  to 
  testing 
  the 
  advantages 
  to 
  be 
  derived 
  from 
  planting 
  

   fry 
  near 
  the 
  ocean, 
  arrangements 
  were 
  made 
  for 
  hatching 
  750,000 
  of 
  

   the 
  eggs 
  collected 
  at 
  the 
  State 
  experimental 
  station 
  at 
  Olema, 
  Cal. 
  

   They 
  were 
  shipped 
  on 
  December 
  31, 
  and 
  the 
  resulting 
  fry 
  were 
  planted 
  

   during 
  February 
  and 
  March 
  in 
  Dutch 
  Bill, 
  Boccacio, 
  Olema, 
  and 
  Bear 
  

   Valley 
  creeks. 
  Their 
  movements 
  were 
  carefully 
  noticed 
  by 
  Messrs. 
  

   A. 
  B. 
  Alexander 
  and 
  K. 
  B. 
  Scofleld. 
  

  

  Clackamas 
  Station, 
  Oregon 
  (W. 
  F. 
  Hubbard, 
  Superintendent). 
  

  

  The 
  superintendent 
  was 
  occupied 
  during 
  a 
  portion 
  of 
  the 
  summer 
  in 
  

   examining 
  a 
  number 
  of 
  tributaries 
  of 
  the 
  Columbia 
  Kiver, 
  with 
  the 
  view 
  

   to 
  establishing 
  auxihary 
  stations, 
  to 
  be 
  operated 
  in 
  connection 
  with 
  the 
  

   station 
  on 
  the 
  Clackamas. 
  As 
  a 
  result 
  of 
  his 
  investigations, 
  arrange- 
  

   ments 
  were 
  made 
  for 
  the 
  collection 
  of 
  eggs 
  on 
  the 
  Salmon 
  Kiver, 
  a 
  

   tributary 
  of 
  the 
  Sandy, 
  and 
  on 
  the 
  Little 
  White 
  Salmon, 
  emptying 
  into 
  

   the 
  Columbia 
  above 
  the 
  Cascades, 
  in 
  the 
  State 
  of 
  Washington. 
  The 
  

   collections 
  on 
  the 
  Snake 
  and 
  Sandy 
  rivers 
  the 
  previous 
  year 
  were 
  so 
  

   small 
  that 
  it 
  was 
  decided 
  not 
  to 
  operate 
  at 
  those 
  points 
  again. 
  

  

  Early 
  in 
  July 
  the 
  station 
  force 
  connuenced 
  the 
  construction 
  of 
  a 
  rack 
  

   330 
  feet 
  long 
  across 
  the 
  Clackamas 
  River. 
  Great 
  difiQculty 
  was 
  expe-' 
  

   rienced 
  in 
  this 
  undertaking 
  on 
  account 
  of 
  the 
  extensive 
  rafting 
  of 
  logs 
  

   and 
  wood 
  from 
  points 
  above, 
  but 
  arrangements 
  were 
  finally 
  made 
  with 
  

   the 
  lumbermen 
  to 
  provide 
  a 
  boom, 
  and 
  a 
  gate 
  was 
  built 
  in 
  the 
  rack 
  to 
  

   permit 
  of 
  the 
  passage 
  of 
  the 
  material. 
  The 
  rack 
  was 
  completed 
  on 
  July 
  

   18, 
  and 
  the 
  force 
  was 
  utilized 
  during 
  the 
  remainder 
  of 
  the 
  summer 
  in 
  

   making 
  repairs 
  to 
  the 
  boats 
  and 
  fishing 
  apparatus, 
  building 
  a 
  trap 
  for 
  

   the 
  capture 
  of 
  spawning 
  fish, 
  and 
  laying 
  a 
  new 
  floor 
  in 
  the 
  hatchery. 
  

   The 
  collection 
  of 
  eggs 
  from 
  the 
  fish 
  below 
  the 
  rack 
  was 
  commenced 
  

   on 
  September 
  11, 
  and 
  operations 
  were 
  continued 
  until 
  October 
  31, 
  the 
  

   total 
  take 
  amounting 
  to 
  1,062,500. 
  On 
  that 
  date 
  a 
  part 
  of 
  the 
  rack 
  was 
  

   carried 
  away 
  by 
  a 
  rise 
  in 
  the 
  river, 
  and, 
  as 
  it 
  was 
  late 
  in 
  the 
  season 
  and 
  

   there 
  appeared 
  to 
  be 
  very 
  few 
  fish 
  below 
  the 
  rack, 
  no 
  attempt 
  was 
  made 
  

   to 
  repair 
  it. 
  

  

  The 
  results 
  of 
  the 
  season's 
  work 
  were 
  very 
  discouraging, 
  as 
  the 
  traps 
  

   and 
  seines 
  had 
  been 
  worked 
  night 
  and 
  day, 
  and 
  gill 
  nets 
  had 
  also 
  been 
  

   fished 
  on 
  the 
  riffles 
  below, 
  where 
  a 
  few 
  salmon 
  were 
  observed 
  spawning. 
  

  

  Early 
  in 
  November 
  the 
  volume 
  of 
  the 
  spring 
  brook 
  was 
  so 
  increased 
  

   by 
  heavy 
  rains 
  that 
  the 
  pumps 
  were 
  discontinued 
  and 
  the 
  supply 
  for 
  

   the 
  hatchery 
  taken 
  from 
  that 
  source. 
  Considerable 
  damage 
  was 
  done 
  to 
  

   the 
  station 
  during 
  the 
  month 
  by 
  high 
  water. 
  The 
  bridge 
  across 
  Clear 
  

   Creek 
  was 
  carried 
  away 
  on 
  the 
  night 
  of 
  November 
  8, 
  and 
  on 
  the 
  13th 
  

   the 
  river 
  rose 
  13 
  feet 
  above 
  its 
  normal 
  level, 
  carrying 
  away 
  the 
  plank 
  

   breakwater 
  built 
  in 
  1877, 
  covering 
  and 
  greatly 
  damaging 
  the 
  land 
  about 
  

   the 
  station, 
  and 
  flooding 
  the 
  hatchery 
  so 
  that 
  a 
  boat 
  could 
  be 
  brought 
  

   into 
  the 
  door. 
  

  

  Shipments 
  of 
  eggs 
  aggregating 
  2,340,000 
  were 
  received 
  from 
  the 
  

   Salmon 
  River 
  station 
  between 
  September 
  11 
  and 
  October 
  G.
