  development 
  of 
  Hudson 
  river 
  waterpowers 
  to 
  far 
  beyond 
  the 
  

   low-water 
  flow 
  of 
  the 
  stream. 
  

  

  Without 
  going 
  into 
  an 
  elaborate 
  discussion 
  at 
  this 
  time, 
  it 
  

   is 
  considered 
  that 
  under 
  existing 
  conditions 
  to 
  substantially 
  

   divert 
  the 
  entire 
  flow 
  of 
  Schroon 
  river 
  would 
  be 
  fairly 
  equivalent 
  

   to 
  taking 
  from 
  500 
  to 
  600 
  cubic 
  feet 
  per 
  second 
  from 
  all 
  water- 
  

   powers 
  on 
  the 
  Hudson 
  river 
  from 
  the 
  George 
  West 
  paper 
  mill 
  at 
  

   Hadley 
  to 
  Troy. 
  This 
  does 
  not 
  mean 
  that 
  600 
  cubic 
  feet 
  per 
  sec- 
  

   ond 
  would 
  be 
  taken 
  away 
  in 
  the 
  low- 
  water 
  months, 
  but 
  that 
  for 
  

   an 
  average 
  of 
  all 
  years 
  the 
  runoff 
  of 
  Schroon 
  catchment 
  area 
  is 
  

   equivalent 
  to 
  about 
  500 
  to 
  600 
  cubic 
  feet 
  continuously 
  when 
  

   applied 
  to 
  Hudson 
  river 
  waterpowers. 
  As 
  a 
  provisional 
  figure, 
  

   accurate 
  enough 
  for 
  present 
  purposes,, 
  we 
  may 
  use 
  550 
  cubic 
  feet 
  

   per 
  second. 
  The 
  following 
  tabulation 
  shows 
  in 
  column 
  (4) 
  the 
  

   net 
  power 
  at 
  75 
  per 
  cent 
  efficiency 
  of 
  550 
  cubic 
  feet

  *The 
  head 
  at 
  the 
  Thomson 
  Pulp 
  and 
  Paper 
  Company's 
  mill 
  is 
  18 
  feet; 
  at 
  the 
  

   Thomson

  Dix 
  sawmill 
  it 
  is 
  from 
  8 
  to 
  10 
  feet. 
  

  

  The 
  foregoing 
  tabulation 
  shows 
  that 
  on 
  the 
  assumed 
  basis 
  

   of 
  550 
  cubic 
  feet 
  per 
  second 
  the 
  total 
  decrease 
  in 
  waterpower 
  

   would 
  be 
  14,695 
  net 
  horsepower, 
  amounting 
  to 
  nearly 
  30 
  per 
  

   cent 
  of 
  the 
  whole. 
  

  

  Let 
  us 
  now 
  examine 
  rapidly 
  as 
  to 
  the 
  approximate 
  value 
  of 
  

   Hudson 
  river 
  waterpower.
