  The 
  diversion 
  of 
  water 
  for 
  the 
  use 
  of 
  Champlain 
  canal 
  is 
  an 
  

   injury 
  to 
  the 
  waterpower 
  at 
  Glens 
  Falls 
  and 
  lower 
  points 
  on 
  the 
  

   river. 
  Since 
  waterpower 
  is 
  much 
  cheaper 
  than 
  steampower, 
  

   the 
  taking 
  of 
  the 
  water 
  of 
  the 
  river 
  away 
  from 
  the 
  manufac- 
  

   turers 
  is 
  a 
  serious 
  matter. 
  In 
  the 
  fourteen 
  years 
  from 
  1882 
  to 
  

   1895 
  the 
  use 
  of 
  waterpower 
  on 
  Hudson 
  river 
  increased 
  237 
  per 
  

   cent. 
  

  

  The 
  upper 
  Hudson 
  storage 
  system 
  is 
  estimated 
  to 
  cost 
  in 
  1904 
  

   from 
  $80 
  to 
  $100 
  per 
  million 
  cubic 
  feet 
  stored, 
  a 
  sum 
  consider- 
  

   ably 
  less 
  than 
  the 
  cost 
  of 
  many 
  other 
  systems. 
  

  

  Storage 
  Reservoirs 
  on 
  Schroon 
  River 
  

  

  In 
  1900 
  the 
  writer 
  reported 
  to 
  the 
  Merchants' 
  Association 
  of 
  

   New 
  York 
  in 
  regard 
  to 
  a 
  reservoir 
  for 
  a 
  water 
  supply 
  to 
  that 
  

   city 
  to 
  be 
  located 
  on 
  Schroon 
  river. 
  The 
  scope 
  of 
  this 
  report 
  

   was 
  as 
  follows: 
  

  

  1) 
  The 
  discussion 
  of 
  a 
  project 
  for 
  supplying 
  five 
  hundred 
  

   million 
  (500,000,000) 
  gallons 
  daily 
  (775 
  cubic 
  feet 
  per 
  second) 
  

   of 
  pure 
  water 
  from 
  a 
  single 
  large 
  reservoir 
  to 
  be 
  located 
  on 
  

   Schroon 
  river. 
  

  

  2) 
  The 
  supplying 
  of 
  the 
  same 
  quantity 
  from 
  Lake 
  George 
  and 
  

   Schroon 
  river. 
  

  

  3) 
  In 
  addition 
  to 
  the 
  storage 
  reservoirs, 
  from 
  which 
  the 
  city 
  

   supply 
  of 
  pure 
  water 
  would 
  be 
  drawn, 
  these 
  two 
  projects 
  further 
  

   included 
  compensating 
  reservoirs 
  large 
  enough 
  to 
  compensate 
  

   for 
  amount 
  of 
  water 
  abstracted 
  for 
  supply 
  of 
  Greater 
  New 
  York. 
  

  

  4) 
  The 
  discussion 
  of 
  a 
  project 
  for 
  supplying 
  a 
  large 
  quantity 
  

   of 
  stored 
  water 
  to 
  Hudson 
  river, 
  in 
  order 
  to 
  hold 
  the 
  point 
  of 
  

   upward 
  flow 
  of 
  salt 
  water 
  through 
  tidal 
  action 
  as 
  far 
  down 
  

   stream 
  as 
  practicable. 
  

  

  The 
  following 
  are 
  the 
  main 
  points 
  embodied 
  in 
  the 
  report 
  to 
  

   the 
  Merchants' 
  Association: 
  

  

  Schroon 
  river 
  flows 
  into 
  Hudson 
  river 
  just 
  above 
  Thurman 
  

   bridge 
  and 
  about 
  fifteen 
  miles 
  north 
  of 
  Hadley. 
  The 
  catchment 
  

   area 
  at 
  its 
  mouth 
  is 
  570 
  square 
  miles. 
  It 
  issues 
  from 
  a 
  region 
  

   with 
  a 
  permanent 
  population 
  of 
  from 
  12 
  to 
  14 
  per 
  square 
  mile. 
  

   The 
  prevailing 
  rocks 
  are 
  granitic, 
  with 
  large 
  areas 
  of 
  fine 
  sand 
  ; 
  

   there 
  are 
  only 
  limited 
  swamp 
  areas.
