  large. 
  Gagings 
  were 
  begun 
  on 
  Salmon 
  river 
  in 
  November, 
  1898. 
  

   The 
  record 
  shows 
  that 
  in 
  April, 
  1899, 
  12.8 
  inches 
  ran 
  off, 
  and 
  

   that 
  the 
  total 
  runoff 
  of 
  the 
  storage 
  period, 
  December, 
  1898, 
  to 
  

   May, 
  1899, 
  inclusive, 
  was 
  25.2 
  inches. 
  The 
  writer 
  had 
  some 
  

   doubt 
  about 
  this 
  record 
  at 
  the 
  time 
  it 
  was 
  taken, 
  although 
  later 
  

   observations 
  seem 
  to 
  indicate 
  that 
  it 
  may 
  have 
  been 
  correct. 
  

  

  The 
  runoff 
  of 
  the 
  east 
  branch 
  of 
  Fish 
  creek 
  at 
  Point 
  Rock 
  begun 
  

   in 
  September, 
  1898, 
  and 
  continued 
  until 
  May, 
  1899, 
  is 
  also 
  very 
  

   large. 
  The 
  record 
  shows 
  that 
  in 
  April, 
  1899, 
  8.0 
  inches 
  ran 
  off. 
  

   The 
  writer's 
  recollection 
  is 
  that 
  the 
  flow 
  was 
  larger 
  than 
  appears 
  

   in 
  the 
  record 
  both 
  on 
  Fish 
  creek 
  and 
  Salmon 
  river, 
  but 
  was 
  

   cut 
  down 
  somewhat 
  because 
  of 
  the 
  unwillingness 
  to 
  assume 
  that 
  

   these 
  large 
  runoffs 
  were 
  right. 
  Further 
  consideration 
  seems 
  to 
  

   indicate 
  that 
  they 
  may 
  perhaps 
  have 
  been 
  true, 
  and 
  it 
  is 
  unfor- 
  

   tunate 
  that 
  gagings 
  have 
  not 
  been 
  kept 
  up 
  continuously 
  from 
  

   that 
  time 
  to 
  the 
  present 
  in 
  order 
  to 
  settle 
  this 
  question 
  of 
  large 
  

   runoff. 
  The 
  catchment 
  of 
  the 
  east 
  branch 
  of 
  Fish 
  creek 
  joins 
  that 
  

   of 
  Salmon 
  river 
  on 
  the 
  east. 
  

  

  The 
  figures 
  given 
  in 
  the 
  Deep 
  Waterways 
  report 
  show 
  that 
  the 
  

   proposed 
  Salmon 
  river 
  reservoir 
  will 
  have 
  a 
  flood 
  area 
  of 
  water 
  

   surface 
  of 
  8.46 
  square 
  miles, 
  storing 
  with 
  this 
  water 
  surface 
  about 
  

   7,500,000,000 
  cubic 
  feet, 
  or 
  storing 
  temporarily 
  on 
  the 
  catchment 
  

   area 
  16.95 
  inches. 
  The 
  tables 
  also 
  show 
  that 
  300 
  cubic 
  feet 
  per 
  

   second 
  may 
  be 
  delivered 
  to 
  the 
  canal 
  during 
  the 
  navigation 
  season 
  

   and 
  still 
  leave 
  some 
  surplus 
  in 
  the 
  reservoir. 
  These 
  computations 
  

   are 
  on 
  the 
  basis 
  of 
  the 
  Hudson 
  river 
  gagings 
  ; 
  in 
  case 
  it 
  turns 
  out 
  

   later 
  on 
  that 
  the 
  flows 
  of 
  the 
  Salmon 
  river 
  are 
  larger 
  than 
  those 
  of 
  

   the 
  Hudson, 
  more 
  than 
  300 
  cubic 
  feet 
  per 
  second 
  can 
  be 
  furnished. 
  

  

  In 
  designing 
  the 
  reservoirs 
  for 
  the 
  supply 
  of 
  the 
  proposed 
  deep 
  

   waterways 
  it 
  was 
  deemed 
  desirable 
  that 
  there 
  be 
  considerable 
  con- 
  

   tingency 
  ; 
  thus, 
  in 
  the 
  Salmon 
  river 
  reservoir, 
  the 
  quantity 
  still 
  in 
  

   the 
  reservoir 
  at 
  the 
  end 
  of 
  1895 
  is 
  5.19 
  inches 
  on 
  the 
  catchment 
  

   area, 
  or 
  about 
  2,250,000,000 
  cubic 
  feet. 
  

  

  An 
  estimate 
  of 
  the 
  cost 
  of 
  this 
  reservoir 
  and 
  of 
  the 
  other 
  works 
  

   on 
  the 
  deep 
  waterways 
  was 
  made 
  in 
  detail. 
  The 
  total 
  cost 
  of 
  the 
  

   Salmon 
  river 
  reservoir 
  was 
  estimated 
  in 
  1899 
  at 
  f 
  1,350,000. 
  Prob- 
  

   ably, 
  in 
  1904, 
  it 
  would 
  cost 
  about 
  25 
  per 
  cent 
  more, 
  or 
  perhaps 
  

   11,678,500. 
  At 
  the 
  latter 
  rate, 
  the 
  cost 
  per 
  1,000,000 
  cubic 
  feet 
  of 
  

   storage 
  becomes
