  The 
  foregoing 
  estimates 
  were 
  made 
  early 
  in 
  1896 
  and 
  due 
  to 
  

   change 
  in 
  conditions, 
  they 
  would 
  be 
  considerably 
  increased 
  in 
  

   1904. 
  

  

  A 
  general 
  estimate 
  of 
  the 
  cost 
  of 
  the 
  single 
  large 
  reservoir 
  in 
  

   Schroon 
  valley 
  shows 
  that 
  with 
  a 
  dam 
  at 
  Tumblehead 
  falls 
  59 
  

   feet 
  in 
  night 
  there 
  would 
  be 
  impounded 
  15,925,000,000 
  cubic 
  

   feet. 
  The 
  preliminary 
  estimate 
  indicates 
  a 
  total 
  cost 
  of 
  $840,- 
  

   000, 
  and 
  a 
  later 
  survey 
  indicates 
  about 
  f 
  1,000,000. 
  The 
  final 
  

   revision 
  of 
  the 
  estimate 
  on 
  completion 
  of 
  the 
  investigation 
  may 
  

   show 
  a 
  somewhat 
  larger 
  figure 
  than 
  this. 
  Even 
  if 
  the 
  cost 
  were 
  

   to 
  be 
  f 
  1,100,000, 
  it 
  would 
  still 
  be 
  exceedingly 
  cheap 
  storage, 
  the 
  

   cost 
  for 
  15,925,000,000 
  cubic 
  feet 
  being 
  on 
  this 
  basis 
  only 
  f 
  69.14 
  

   per 
  million 
  cubic 
  feet 
  stored. 
  

  

  In 
  order 
  to 
  appreciate 
  fully 
  the 
  low 
  cost 
  of 
  these 
  reservoirs, 
  it 
  

   may 
  be 
  mentioned 
  that 
  reservoirs 
  for 
  municipal 
  water 
  supplies 
  

   frequently 
  cost 
  from 
  $5000 
  to 
  $10,000 
  per 
  million 
  cubic 
  feet 
  

   stored. 
  In 
  specially 
  unfavorable 
  cases 
  the 
  cost 
  is 
  even 
  higher 
  

   than 
  this— 
  it 
  may 
  be 
  as 
  high 
  as 
  $12,000 
  to 
  $15,000 
  per 
  million 
  

   cubic 
  feet 
  stored. 
  Small 
  reservoirs 
  sometimes 
  cost 
  from 
  $6000 
  

   to 
  $8000 
  per 
  1,000,000 
  gallons 
  stored. 
  

  

  The 
  dam 
  at 
  Tumblehead 
  falls 
  would 
  be 
  located 
  just 
  below 
  the 
  

   outlet 
  of 
  Brant 
  lake, 
  the 
  elevation 
  of 
  the 
  water 
  surface 
  of 
  which 
  

   is 
  801 
  feet. 
  The 
  flow 
  line 
  of 
  the 
  proposed 
  reservoir 
  has 
  been 
  

   placed 
  at 
  an 
  elevation 
  of 
  840 
  feet, 
  thus 
  giving 
  a 
  depth 
  of 
  39 
  feet 
  

   over 
  the 
  surface 
  of 
  Brant 
  lake, 
  a 
  depth 
  of 
  33 
  feet 
  over 
  the 
  sur- 
  

   face 
  of 
  Schroon 
  lake, 
  and 
  a. 
  depth 
  of 
  20 
  feet 
  over 
  Paradox 
  lake. 
  

   With 
  the 
  reservoir 
  full 
  or 
  nearly 
  full, 
  there 
  would 
  be 
  continuous 
  

   navigation 
  from 
  the 
  head 
  of 
  Brant 
  lake 
  to 
  the 
  head 
  of 
  Paradox 
  

   lake 
  of 
  about 
  35 
  miles. 
  The 
  villages 
  of 
  South 
  Horicon, 
  Barton- 
  

   ville, 
  Starbuckville, 
  and 
  parts 
  of 
  Pottersville 
  and 
  Chester 
  are 
  

   within 
  the 
  flow 
  line 
  of 
  this 
  reservoir. 
  

  

  Indian 
  lake 
  is 
  another 
  large 
  reservoir 
  on 
  the 
  headwaters 
  of 
  

   Hudson 
  river, 
  that 
  has 
  been 
  described 
  on 
  a 
  preceding 
  page. 
  

  

  Piseco 
  lake 
  is 
  another 
  large 
  reservoir 
  which 
  may 
  be 
  con- 
  

   structed 
  on 
  the 
  upper 
  Hudson 
  at 
  low 
  cost. 
  It 
  is 
  estimated 
  that 
  

   a 
  storage 
  of 
  1,725,000,000 
  cubic 
  feet 
  may 
  be 
  made 
  at 
  an 
  expendi- 
  

   ture 
  of 
  $70,000, 
  or 
  at 
  an 
  average 
  cost 
  per 
  million 
  cubic 
  feet 
  

   stored 
  of 
  $40.
