  carried 
  along 
  through 
  each 
  water 
  year, 
  to 
  the 
  end 
  of 
  November 
  

   1899. 
  

  

  This 
  computation 
  shows 
  that 
  for 
  a 
  storage 
  of 
  18 
  inches 
  on 
  

   the 
  catchment 
  area 
  and 
  a 
  uniform 
  outflow 
  of 
  775 
  cubic 
  feet 
  per 
  

   second 
  the 
  total 
  waste 
  in 
  the 
  twelve-year 
  period 
  would 
  have 
  

   been 
  only 
  13.81 
  inches. 
  A 
  similar 
  computation 
  has 
  been 
  made 
  

   for 
  a 
  storage 
  of 
  13.5 
  inches 
  and 
  uniform 
  outflow 
  of 
  650 
  cubic 
  

   feet 
  per 
  second, 
  in 
  which 
  the 
  waste 
  would 
  have 
  been 
  55.36 
  inches, 
  

   ■amounting 
  to 
  a 
  mean 
  waste 
  per 
  year 
  of 
  4.61 
  inches. 
  

  

  The 
  distance 
  from 
  Hadley 
  to 
  proposed 
  site 
  of 
  iSchroon 
  valley 
  

   barrage 
  at 
  Tumblehead 
  falls 
  — 
  measured 
  along 
  the 
  thread 
  of 
  

   Hudson 
  and 
  Schroon 
  valleys 
  — 
  is 
  about 
  29 
  miles. 
  Of 
  this 
  about 
  

   14 
  miles 
  is 
  in 
  Schroon 
  valley. 
  The 
  village 
  of 
  Warrensburg, 
  

   with 
  a 
  population 
  of 
  about 
  1000 
  in 
  1900, 
  lies 
  on 
  Schroon 
  

   river, 
  three 
  miles 
  above 
  its 
  mouth. 
  At 
  and 
  in 
  the 
  vicinity 
  of 
  

   this 
  place 
  waterpower 
  to 
  the 
  extent 
  of 
  1627 
  net 
  horsepower 
  

   (2167 
  gross 
  horsepower) 
  has 
  been 
  developed 
  on 
  Schroon 
  river. 
  

   The 
  largest 
  block 
  of 
  power 
  at 
  a 
  single 
  point 
  is 
  at 
  the 
  dam 
  of 
  

   the 
  Schroon 
  River 
  Pulp 
  Company, 
  one 
  and 
  one 
  half 
  miles 
  below 
  

   Warrensburg, 
  where 
  1086 
  net 
  horsepower 
  are 
  in 
  use. 
  Owing 
  to 
  

   the 
  equalizing 
  effect 
  of 
  Schroon 
  lake, 
  these 
  powers 
  are 
  all 
  fairly 
  

   permanent 
  except 
  at 
  the 
  pulp 
  mill, 
  which 
  is 
  sometimes 
  short 
  of 
  

   water 
  in 
  late 
  summer 
  and 
  fall 
  months. 
  

  

  The 
  water-surface 
  elevation 
  of 
  Schroon 
  river 
  at 
  its 
  mouth, 
  

   near 
  Thurman, 
  is 
  approximately 
  620 
  + 
  T. 
  W. 
  At 
  Tumblehead 
  

   falls 
  the 
  elevation 
  is 
  about 
  780 
  + 
  T. 
  W. 
  There 
  is, 
  therefore, 
  a 
  

   total 
  fall 
  of 
  160 
  feet 
  between 
  Tumblehead 
  falls 
  and 
  mouth 
  of 
  

   stream. 
  Of 
  this 
  39 
  feet 
  is 
  included 
  in 
  the 
  dams 
  at 
  Warrensburg 
  

   village 
  and 
  the 
  Schroon 
  River 
  Pulp 
  Company's 
  power, 
  leaving 
  

   121 
  feet 
  still 
  undeveloped. 
  It 
  seems 
  very 
  desirable, 
  in 
  case 
  

   Schroon 
  valley 
  reservoir 
  is 
  constructed, 
  that 
  the 
  waterpower 
  

   possibilities 
  of 
  the 
  stream 
  be 
  preserved. 
  A 
  uniform 
  outflow 
  of 
  

   775 
  cubic 
  feet 
  per 
  second 
  would 
  yield, 
  on 
  121 
  feet 
  fall, 
  10,639 
  

   gross 
  horsepower. 
  

  

  In 
  order 
  to 
  preserve 
  present 
  waterpower 
  s 
  and 
  ultimately 
  

   utilize 
  the 
  undeveloped 
  fall, 
  it 
  would 
  be 
  necessary 
  to 
  let 
  the 
  

   water 
  discharged 
  from 
  the 
  reservoir 
  at 
  Tumblehead 
  falls 
  flow 
  

   -down 
  the 
  present 
  channel 
  of 
  Schroon 
  river 
  to 
  a 
  diversion 
  weir, 
  to
