  of 
  fish-food 
  fouud. 
  It 
  was 
  learned 
  that 
  a 
  considerable 
  number 
  of 
  

   salmon 
  run 
  into 
  one 
  or 
  more 
  of 
  these 
  lakes; 
  and 
  that 
  all 
  of 
  them, 
  but 
  

   particularly 
  Whoahink, 
  are 
  well 
  supplied 
  with 
  the 
  native 
  black-spotted 
  

   trout, 
  which 
  attains 
  a 
  large 
  size 
  and 
  possesses 
  excellent 
  game 
  qualities. 
  

   The 
  planting 
  of 
  black 
  bass 
  in 
  Tsiltcoos 
  Lake 
  would, 
  in 
  all 
  probability, 
  

   prove 
  detrimental 
  to 
  the 
  native 
  trout 
  and 
  the 
  salmon, 
  while 
  the 
  eastern 
  

   brook 
  trout 
  would 
  probably 
  never 
  become 
  so 
  well 
  established 
  as 
  to 
  

   render 
  these 
  lakes 
  more 
  attractive 
  to 
  anglers 
  than 
  they 
  now 
  are. 
  

  

  UPPER 
  KLAMATH 
  LAKE, 
  OREGON. 
  

  

  In 
  18S9 
  the 
  Fish 
  Commission 
  planted 
  400,000 
  fry 
  of 
  the 
  common 
  

   whitefish 
  {Coregonus 
  clupeiformis) 
  in 
  Upper 
  Klamath 
  Lake. 
  Sufficient 
  

   time 
  having 
  elapsed 
  to 
  enable 
  the 
  species 
  to 
  become 
  established 
  if 
  the 
  

   conditions 
  were 
  favorable, 
  investigations 
  were 
  made 
  to 
  determine 
  the 
  

   result 
  of 
  the 
  plant. 
  Messrs. 
  Meek 
  and 
  Alexander 
  reached 
  the 
  lake 
  

   October 
  31, 
  and 
  continued 
  their 
  observations 
  until 
  ^N'ovember 
  7. 
  The 
  

   parts 
  of 
  the 
  lake 
  which 
  Avere 
  most 
  carefully 
  examined 
  were 
  Pelican 
  Bay 
  

   and 
  vicinity, 
  and 
  the 
  extreme 
  southern 
  end, 
  near 
  Klamath 
  Falls. 
  The 
  

   lake 
  was 
  found 
  to 
  be 
  comparatively 
  shallow, 
  the 
  greatest 
  depth 
  in 
  the 
  

   places 
  where 
  soundings 
  were 
  taken 
  being 
  17 
  feet, 
  while 
  the 
  usual 
  depth 
  

   did 
  not 
  exceed 
  6 
  or 
  7 
  feet. 
  The 
  bottom 
  consists 
  largely 
  of 
  a 
  loose 
  layer 
  

   of 
  decaying 
  vegetation 
  from 
  the 
  extensive 
  tule 
  marshes 
  adjoining 
  the 
  

   lake. 
  Fish-food, 
  chiefly 
  small 
  crustaceans 
  and 
  insect 
  larvjie, 
  was 
  fonud 
  

   to 
  be 
  very 
  plentiful. 
  Trials 
  were 
  made 
  with 
  seines, 
  gill 
  nets, 
  set 
  lines, 
  

   and 
  other 
  apparatus, 
  but 
  no 
  whitefish 
  were 
  taken, 
  nor 
  did 
  inquiry 
  among 
  

   the 
  people 
  on 
  the 
  shores 
  of 
  the 
  lakes 
  elicit 
  any 
  information 
  showing 
  

   that 
  the 
  fry 
  have 
  survived. 
  The 
  general 
  physical 
  characteristics 
  of 
  the 
  

   lake 
  hardly 
  warrant 
  the 
  expectation 
  that 
  the 
  common 
  Avhitefish 
  can 
  be 
  

   acclimatized. 
  

  

  The 
  lake 
  is, 
  however, 
  well 
  supplied 
  with 
  one 
  of 
  the 
  largest 
  ami 
  best 
  

   sj)ecies 
  of 
  American 
  trout. 
  It 
  attains 
  a 
  weight 
  of 
  17 
  pounds 
  and 
  is 
  

   easily 
  captured 
  by 
  trolling, 
  and 
  is 
  so 
  abundant 
  as 
  to 
  attract 
  many 
  

   anglers 
  to 
  the 
  lake 
  each 
  season. 
  The 
  lake 
  is 
  also 
  inhabited 
  by 
  four 
  

   or 
  five 
  species 
  of 
  suckers, 
  several 
  of 
  which 
  are 
  exceedingly 
  numerous, 
  

   of 
  large 
  size, 
  and 
  constitute 
  an 
  important 
  part 
  of 
  the 
  food 
  supply 
  of 
  

   the 
  Indians 
  upon 
  the 
  Klamath 
  Reservation. 
  

  

  CRATER 
  LAKE, 
  OREGON. 
  

  

  In 
  response 
  to 
  the 
  request 
  of 
  citizens 
  of 
  Klamath 
  Falls, 
  Ashland, 
  

   and 
  Medford, 
  Oreg., 
  and 
  of 
  the 
  Mazamas, 
  an 
  association 
  of 
  mountain 
  

   climbers 
  with 
  headcpiarters 
  at 
  Portland, 
  Oreg., 
  the 
  Commission 
  sent 
  

   Messrs. 
  Evermann 
  and 
  Cox 
  to 
  Crater 
  Lake 
  to 
  determine 
  whether 
  it 
  

   was 
  advisable 
  to 
  plant 
  trout 
  in 
  the 
  lake, 
  which 
  now 
  contains 
  no 
  fish 
  

   whatever. 
  Six 
  days 
  in 
  August 
  were 
  devoted 
  to 
  an 
  examination 
  of 
  the 
  

   physical 
  and 
  biological 
  features 
  of 
  the 
  lake. 
  

  

  This 
  lake 
  is 
  on 
  the 
  crest 
  of 
  the 
  Cascade 
  Mountains, 
  about 
  100 
  miles 
  

   east 
  of 
  Ashland. 
  It 
  is 
  unique 
  in 
  character 
  and 
  ranks 
  among 
  the 
  most
