  Schroon 
  river 
  has 
  a 
  total 
  catchment 
  area 
  above 
  its 
  mouth 
  of 
  

   570 
  square 
  miles. 
  The 
  topography 
  of 
  the 
  Schroon 
  area 
  is 
  such 
  

   as 
  to 
  admit 
  of 
  two 
  distinct 
  lines 
  of 
  treatment 
  — 
  either 
  to 
  construct 
  

   one 
  large 
  dam 
  at 
  Tumblehead 
  falls, 
  about 
  a 
  mile 
  below 
  South 
  

   Horicon, 
  or 
  to 
  construct 
  a 
  series 
  of 
  16 
  to 
  18 
  small 
  dams 
  at 
  various 
  

   points 
  in 
  the 
  area. 
  In 
  either 
  case 
  it 
  is 
  possible 
  to 
  control 
  sub- 
  

   stantially 
  the 
  full 
  flow 
  above 
  Tumblehead 
  falls, 
  and 
  the 
  decision 
  

   of 
  which 
  is 
  better 
  will 
  turn 
  chiefly 
  on 
  the 
  question 
  of 
  relative 
  

   cost, 
  the 
  estimate 
  taking 
  into 
  account 
  the 
  fact 
  that 
  it 
  will 
  cost 
  

   much 
  more 
  to 
  operate 
  a 
  large 
  number 
  of 
  reservoirs 
  than 
  to 
  operate 
  

   one. 
  The 
  following

  areas

  the
