  OPERATIONS. 
  

  

  Pacific 
  coast 
  and 
  Alaska 
  stations. 
  — 
  No 
  improvement 
  has 
  occurred 
  

   in 
  the 
  conditions 
  which 
  have 
  prevailed 
  for 
  some 
  years 
  in 
  the 
  Sacra- 
  

   mento 
  Kiver 
  and 
  tributaries, 
  resulting 
  in 
  a 
  general 
  decline 
  of 
  the 
  

   salmon 
  runs, 
  and 
  a 
  relative 
  falling 
  off 
  in 
  the 
  output 
  of 
  the 
  Bureau's 
  

   California 
  stations. 
  A 
  large 
  run 
  of 
  salmon 
  was 
  reported 
  in 
  the 
  Sac- 
  

   ramento 
  Kiver 
  in 
  the 
  fall 
  of 
  1912, 
  but 
  owing 
  to 
  extremely 
  low 
  water 
  

   during 
  the 
  spawning 
  season 
  comparatively 
  few 
  of 
  the 
  fish 
  were 
  able 
  

   to 
  enter 
  the 
  tributaries 
  on 
  which 
  the 
  hatcheries 
  are 
  located. 
  Later 
  

   on, 
  unusually 
  heavy 
  freshets 
  partly 
  wrecked 
  the 
  retaining 
  racks 
  

   and 
  permitted 
  the 
  impounded 
  fish 
  to 
  escape. 
  An 
  attempt 
  was 
  made 
  

   late 
  in 
  the 
  fall 
  to 
  secure 
  eggs 
  from 
  commercial 
  fishermen 
  operating 
  

   in 
  the 
  Sacramento 
  River, 
  near 
  Tehama, 
  Cal., 
  but 
  no 
  ripe 
  fish 
  were 
  

   found, 
  and 
  the 
  fishermen 
  abandoned 
  the 
  work 
  early 
  on 
  account 
  of 
  

   the 
  low 
  market 
  value 
  of 
  their 
  catch. 
  The 
  entire 
  collection 
  of 
  chinook 
  

   salmon 
  eggs 
  for 
  the 
  Baird, 
  Battle 
  Creek, 
  and 
  Mill 
  Creek 
  stations 
  

   amounted 
  to 
  20,111,800. 
  Low- 
  water 
  stages 
  also 
  existed 
  throughout 
  

   the 
  season 
  in 
  Cottonwood 
  Creek, 
  at 
  Hornbrook, 
  Cal., 
  and 
  in 
  the 
  

   Klamath 
  River, 
  at 
  Klamathon, 
  Cal., 
  reducing 
  the 
  collections 
  of 
  rain- 
  

   bow 
  trout 
  and 
  silver 
  salmon 
  eggs 
  at 
  these 
  points 
  below 
  those 
  of 
  the 
  

   preceding 
  year. 
  

  

  Increased 
  efforts 
  and 
  the 
  generally 
  favorable 
  climatic 
  conditions 
  

   prevailing 
  in 
  Oregon 
  resulted 
  in 
  substantial 
  gains 
  in 
  the 
  output 
  of 
  

   fish 
  from 
  the 
  stations 
  in 
  that 
  State. 
  There 
  was 
  an 
  unusually 
  heavy 
  

   run 
  of 
  chinook 
  salmon 
  in 
  the 
  Columbia 
  River 
  and 
  tributaries, 
  con- 
  

   tinuing 
  from 
  early 
  in 
  September 
  until 
  late 
  in 
  the 
  fall. 
  On 
  the 
  Little 
  

   Wliite 
  Salmon 
  River 
  30,595,000 
  eggs 
  were 
  secured, 
  fillmg 
  the 
  hatch- 
  

   ery 
  to 
  its 
  capacity 
  and 
  necessitating 
  the 
  transfer 
  of 
  large 
  numbers 
  of 
  

   eggs 
  to 
  other 
  stations 
  to 
  relieve 
  the 
  congested 
  condition. 
  The 
  col- 
  

   lections 
  at 
  the 
  Big 
  Wliite 
  Salmon 
  station 
  were 
  supplemented 
  by 
  eggs 
  

   derived 
  from 
  brood 
  fish 
  purchased 
  of 
  trap 
  fishermen 
  operating 
  in 
  the 
  

   Columbia 
  River, 
  the 
  fish 
  thus 
  obtained 
  being 
  towed 
  to 
  the 
  station 
  and 
  

   held 
  in 
  a 
  small 
  stream 
  on 
  the 
  reservation 
  for 
  the 
  ripening 
  of 
  their. 
  

   eggs. 
  The 
  output 
  of 
  salmon 
  fry 
  at 
  the 
  two 
  Columbia 
  River 
  stations 
  

   was 
  the 
  largest 
  in 
  their 
  history. 
  The 
  egg 
  collections 
  on 
  the 
  Little 
  

   White 
  Salmon 
  exceeded 
  those 
  of 
  any 
  previous 
  year 
  by 
  12,000,000, 
  

   and 
  when 
  the 
  work 
  was 
  discontinued 
  on 
  October 
  7, 
  owing 
  to 
  lack 
  of 
  

   hatching 
  facilities, 
  ripe 
  salmon 
  were 
  still 
  available. 
  

  

  The 
  same 
  conditions 
  governing 
  the 
  run 
  of 
  salmon 
  in 
  the 
  Columbia 
  

   River 
  existed 
  in 
  other 
  streams 
  in 
  Oregon, 
  and 
  resulted 
  in 
  an 
  increased 
  

   output 
  of 
  silver 
  salmon 
  and 
  steelhead 
  trout. 
  The 
  Cazadero 
  field 
  

   station, 
  on 
  the 
  upper 
  Clackamas 
  River, 
  having 
  been 
  cut 
  off 
  from 
  

   the 
  free 
  passage 
  of 
  fish 
  by 
  the 
  recent 
  construction 
  of 
  an 
  80-foot 
  dam, 
  

   a 
  new 
  site 
  for 
  the 
  conduct 
  of 
  operations 
  was 
  selected 
  at 
  a 
  point 
  on
