  In 
  the 
  low 
  level 
  project 
  it 
  is 
  proposed 
  to 
  convert 
  Oneida 
  lake 
  

   into 
  a 
  storage 
  reservoir, 
  and 
  by 
  cutting 
  a 
  channel 
  through 
  the 
  Kome 
  

   divide, 
  navigation 
  at 
  lake 
  level 
  could 
  be 
  extended 
  to 
  the 
  Mohawk 
  

   river 
  at 
  Frankfort, 
  a 
  distance 
  of 
  seventy-two 
  miles 
  from 
  the 
  lock 
  

   at 
  the 
  western 
  end 
  of 
  the 
  level, 
  2.5 
  miles 
  east 
  of 
  Fulton. 
  From 
  

   Frankfort 
  to 
  the 
  Hudson 
  the 
  route 
  is 
  practically 
  a 
  rectification 
  

   of 
  the 
  Mohawk 
  river 
  to 
  Rotterdam 
  Junction, 
  thence 
  for 
  three 
  miles 
  

   along 
  the 
  south 
  side 
  of 
  the 
  Mohawk 
  valley 
  and 
  across 
  the 
  divide 
  

   to 
  the 
  head 
  of 
  the 
  Normans 
  kill, 
  which 
  stream 
  enters 
  the 
  Hudson 
  

   a 
  short 
  distance 
  below 
  Albany. 
  

  

  The 
  water 
  supply 
  of 
  the 
  high 
  level 
  project, 
  including 
  evapora- 
  

   tion, 
  leakage, 
  water-power, 
  waste, 
  etc. 
  is 
  taken 
  at 
  1600 
  cubic 
  feet 
  

   per 
  second 
  for 
  a 
  30-foot 
  channel 
  and 
  at 
  1400 
  cubic 
  feet 
  per 
  second 
  

   for 
  a 
  21-foot 
  channel. 
  In 
  order 
  to 
  provide 
  this 
  quantity, 
  a 
  reser- 
  

   voir 
  was 
  located 
  in 
  the 
  valley 
  of 
  Black 
  river, 
  with 
  surface 
  area, 
  

   when 
  full, 
  of 
  73 
  square 
  miles 
  and 
  an 
  impounding 
  capacity 
  of 
  

   57,000,000,000 
  cubic 
  feet, 
  and 
  one 
  in 
  Salmon 
  river 
  valley 
  of 
  8.5 
  

   square 
  miles 
  area 
  and 
  a 
  storage 
  capacity 
  of 
  over 
  7,000,000,000 
  

   cubic 
  feet. 
  The 
  storage 
  of 
  the 
  Black 
  river 
  reservoir 
  would 
  be 
  suffi- 
  

   cient 
  to 
  maintain 
  a 
  supply 
  except 
  in 
  periods 
  of 
  low 
  precipitation, 
  

   when 
  additional 
  supply 
  might 
  be 
  needed 
  from 
  the 
  Salmon 
  river 
  

   reservoir. 
  The 
  Black 
  river 
  reservoir 
  also 
  provided 
  for 
  maintain- 
  

   ing 
  the 
  waterpower 
  on 
  Black 
  river 
  below 
  the 
  reservoir. 
  

  

  A 
  study 
  was 
  also 
  made 
  of 
  an 
  alternative 
  tunnel 
  project 
  as 
  a 
  

   substitute 
  for 
  the 
  feeder 
  line, 
  which 
  has 
  sufficient 
  merit 
  to 
  warrant 
  

   further 
  investigation. 
  This 
  tunnel 
  would 
  leave 
  the 
  south 
  end 
  of 
  

   the 
  Black 
  river 
  reservoir 
  at 
  Lyon 
  Falls 
  and 
  open 
  into 
  the 
  upper 
  

   Mohawk 
  at 
  the 
  village 
  of 
  North 
  Western, 
  a 
  distance 
  of 
  20.5 
  miles 
  

   from 
  the 
  reservoir, 
  and 
  thence 
  discharge 
  from 
  the 
  channel 
  of 
  the 
  

   Mohawk 
  into 
  the 
  waterway 
  near 
  Rome. 
  It 
  is 
  considered 
  that 
  the 
  

   tunnel 
  plan 
  would 
  be 
  preferable 
  because 
  the 
  amount 
  of 
  waste 
  and 
  

   cost 
  of 
  maintenance 
  would 
  be 
  much 
  less 
  than 
  for 
  the 
  open 
  feeder. 
  

   The 
  danger 
  of 
  accident 
  would 
  be 
  reduced 
  to 
  a 
  minimum. 
  The 
  

   costs 
  of 
  the 
  two 
  systems, 
  as 
  estimated, 
  are 
  approximately 
  the 
  

   same. 
  

  

  The 
  estimated 
  cost 
  for 
  a 
  30-foot 
  channel 
  on 
  the 
  high 
  level 
  pro- 
  

   ject 
  is 
  |195,870,000. 
  

  

  For 
  the 
  low 
  level 
  project, 
  the 
  estimated 
  cost 
  of 
  a 
  30-foot 
  channel 
  

   is 
  $199,926,000.
