  be 
  located 
  just 
  above 
  the 
  mouth, 
  at 
  which 
  point 
  a 
  conduit 
  of 
  

   775 
  cubic 
  feet 
  per 
  second 
  capacity 
  would 
  begin. 
  This 
  diversion 
  

   weir 
  would 
  be 
  sixteen 
  miles 
  above 
  Hartley, 
  but 
  it 
  is 
  considered 
  

   that 
  the 
  additional 
  cost 
  of 
  extending 
  the 
  conduit 
  this 
  distance 
  

   would 
  be 
  compensated 
  for 
  by 
  the 
  keeping 
  of 
  pure 
  Schroon 
  river 
  

   water 
  entirely 
  separate 
  from 
  balance 
  of 
  Hudson 
  river 
  water. 
  

  

  In 
  proposing 
  such 
  separation 
  it 
  is 
  not 
  intended 
  to 
  imply 
  that 
  

   Hudson 
  river 
  water 
  at 
  Hadley 
  is 
  not 
  suited 
  for 
  a 
  public 
  supply. 
  

   In 
  any 
  case 
  upper 
  Hudson 
  water 
  is 
  very 
  pure, 
  but 
  due 
  to 
  relatively 
  

   somewhat 
  more 
  extensive 
  swamp 
  areas 
  to 
  north 
  of 
  mouth 
  of 
  

   Schroon 
  river, 
  Hudson 
  river 
  water 
  at 
  Hadley, 
  as 
  a 
  whole, 
  is 
  not 
  

   equal 
  to 
  that 
  of 
  Schroon 
  river. 
  The 
  purifying 
  effect 
  of 
  wind 
  and 
  

   sunlight 
  on 
  the 
  extended 
  water 
  areas 
  of 
  Schroon, 
  Brant 
  and 
  Para- 
  

   dox 
  lakes 
  is 
  taken 
  into 
  account 
  in 
  reaching 
  this 
  conclusion. 
  

  

  Another 
  important 
  reason 
  for 
  extending 
  conduit 
  to 
  diversion 
  

   weir 
  just 
  above 
  mouth 
  of 
  Schroon 
  river 
  may 
  be 
  found 
  in 
  consider- 
  

   ing 
  that 
  much 
  the 
  cheapest 
  way 
  to 
  reimburse 
  waterpower 
  owners 
  

   on 
  Hudson 
  river 
  for 
  diversion 
  of 
  775 
  cubic 
  feet 
  per 
  second 
  will 
  be 
  

   by 
  constructing 
  compensation 
  reservoirs. 
  Some 
  of 
  these 
  would 
  

   be 
  located 
  on 
  Sacandaga 
  river, 
  which 
  flows 
  into 
  Hudson 
  river 
  at 
  

   Hadley, 
  but 
  nevertheless 
  several 
  would 
  be 
  on 
  main 
  North 
  river 
  

   above 
  Thurman. 
  If 
  proposed 
  additional 
  water 
  supply 
  of 
  Greater 
  

   New 
  York 
  were 
  taken 
  at 
  Hadley, 
  then 
  all 
  compensating 
  reservoirs 
  

   should 
  be 
  thoroughly 
  cleared 
  and 
  stripped, 
  the 
  same 
  as 
  is 
  pro- 
  

   posed 
  for 
  Schroon 
  valley 
  reservoir. 
  Even 
  after 
  completion 
  of 
  

   such 
  extensive 
  work, 
  the 
  conditions 
  at 
  several 
  reservoir 
  sites 
  to 
  

   north 
  of 
  Thurman 
  are 
  not 
  such 
  as 
  to 
  yield 
  an 
  ideal 
  water 
  without 
  

   filtration. 
  There 
  are 
  extensive 
  muck 
  areas 
  which 
  now 
  discolor 
  the 
  

   water 
  and 
  taint 
  it 
  with 
  an 
  offensive 
  odor. 
  Filtration 
  would, 
  of 
  

   course, 
  make 
  any 
  of 
  these 
  waters 
  ideal, 
  and 
  probably 
  for 
  a 
  thor- 
  

   ough 
  study 
  of 
  the 
  project 
  in 
  all 
  of 
  its 
  phases 
  estimates 
  should 
  be 
  

   worked 
  out 
  showing 
  approximate 
  cost 
  of 
  taking 
  775 
  cubic 
  feet 
  

   per 
  second 
  at 
  Hadley, 
  with 
  all 
  stripping 
  of 
  reservoirs 
  omitted, 
  

   but 
  including 
  the 
  cost 
  of 
  a 
  filtration 
  plant 
  capable 
  of 
  handling 
  775 
  

   cubic 
  feet 
  per 
  second. 
  As 
  regards 
  quality 
  of 
  the 
  municipal 
  

   supply, 
  such 
  treatment 
  would 
  place 
  this 
  project 
  essentially 
  on 
  a 
  

   par 
  with 
  the 
  Vyrnwy 
  supply 
  for 
  Liverpool, 
  where 
  the 
  water 
  of 
  a 
  

   sparsely 
  populated 
  mountainous 
  area 
  is 
  filtered, 
  largely 
  to 
  remove 
  

   vegetable 
  discoloration.
