  17 
  to

  feet. 
  The 
  taking 
  of 
  an 
  additional 
  strip, 
  for 
  

   sanitary 
  protection, 
  as 
  in 
  Schroon 
  valley, 
  would 
  include 
  nearly 
  all 
  

   of 
  these, 
  as 
  well 
  as 
  the 
  village 
  of 
  Caldwell. 
  

  

  Basing 
  the 
  Lake 
  George 
  project 
  on 
  775 
  cubic 
  feet 
  per 
  second 
  

   supply, 
  the 
  same 
  as 
  for 
  Schroon 
  valley, 
  it 
  is 
  found 
  that 
  from 
  300 
  

   to 
  350 
  cubic 
  feet 
  per 
  second 
  would 
  come 
  from 
  the 
  Lake 
  George 
  

   catchment 
  area. 
  The 
  balance 
  can 
  be 
  obtained 
  from 
  Schroon 
  

   valley 
  by 
  a 
  tunnel 
  through 
  the 
  intervening 
  ridge 
  ait 
  a 
  point 
  above 
  

   Warrensburg, 
  where 
  the 
  distance 
  across 
  is 
  only 
  3.25 
  miles 
  (17,160 
  

   linear 
  feet). 
  A 
  diversion 
  weir 
  with 
  proper 
  regulating 
  head- 
  

   works 
  would 
  be 
  required 
  on 
  Scnroon 
  river. 
  The 
  elevation 
  of 
  

   Schroon; 
  river 
  at 
  the 
  point 
  of 
  diversion 
  is 
  about 
  670 
  feet. 
  With 
  

   Lake 
  George 
  takem 
  at 
  323 
  feet, 
  the 
  difference 
  becomes 
  347 
  feet. 
  

  

  For 
  several 
  months 
  of 
  each 
  year 
  the 
  runoff 
  of 
  Schroon 
  river 
  

   exceeds 
  550 
  cubic 
  feet 
  per 
  second, 
  the 
  mean 
  runoff 
  for 
  four 
  years 
  

   being 
  1112 
  cubic 
  feet 
  per 
  second. 
  Hence, 
  a 
  mean 
  of 
  550 
  cubic 
  

   feet 
  per 
  second 
  could 
  be 
  diverted 
  into 
  Lake 
  George 
  and 
  still 
  leave 
  

   Hudson 
  river 
  waterpowers 
  substantially 
  unimpaired. 
  The 
  con- 
  

   necting 
  tunnel 
  should 
  therefore 
  have 
  a 
  capacity 
  of 
  about 
  2600 
  

   to 
  2800 
  cubic 
  feet 
  per 
  second 
  in 
  order 
  to 
  divert 
  the 
  full 
  flood-flows.

  this 
  estimate 
  with 
  the 
  foregoing 
  for

  project 
  fairly 
  leads 
  to 
  the 
  conclusion 
  that; 
  independent 
  of 
  

   lack 
  of 
  elevation 
  ait 
  Lake 
  George, 
  the
