  storage 
  of 
  15,000,000,000 
  cubic 
  feet 
  can 
  be 
  made 
  for 
  somewhat 
  

   less 
  than 
  the 
  cost 
  of 
  7,300,000,000 
  cubic 
  feet 
  at 
  Mount 
  Morris; 
  

   or, 
  as 
  a 
  general 
  statement, 
  we 
  may 
  say 
  that 
  a 
  given 
  expenditure 
  

   at 
  Portage 
  produces 
  double 
  the 
  storage 
  that 
  it 
  will 
  produce 
  at 
  

   Mount 
  Morris. 
  The 
  Portage 
  reservoir 
  develops 
  the 
  full 
  capacity 
  

   of 
  the 
  catchment 
  area 
  for 
  such 
  a 
  dry 
  year 
  as 
  1895. 
  It 
  is 
  con- 
  

   sidered 
  that 
  this 
  full 
  development 
  is 
  necessary 
  in 
  order 
  to 
  obtain 
  

   the 
  most 
  satisfactory 
  results 
  in 
  river 
  regulation. 
  

  

  As 
  reasons 
  in 
  detail 
  for 
  preferring 
  the 
  Portage 
  site 
  to 
  that 
  at 
  

   Mount 
  Morris, 
  the 
  following 
  may 
  be 
  mentioned 
  : 
  

  

  1) 
  The 
  Portage 
  site 
  affords 
  more 
  water 
  for 
  a 
  given 
  expendi- 
  

   ture. 
  

  

  2) 
  The 
  Portage 
  site 
  is 
  considered 
  safer 
  than 
  the 
  Mount 
  Mor- 
  

   ris 
  site. 
  As 
  shown 
  in 
  the 
  Genesee 
  Storage 
  Keports 
  of 
  1893-94, 
  

   the 
  shales 
  at 
  Mount 
  Morris 
  are 
  open; 
  and 
  while 
  it 
  is, 
  without 
  

   doubt, 
  possible 
  to 
  make 
  a 
  safe 
  dam 
  there, 
  it 
  would 
  be 
  at 
  much 
  

   greater 
  cost 
  than 
  at 
  Portage. 
  

  

  3) 
  The 
  material 
  for 
  the 
  dam 
  is 
  nearly 
  all 
  on 
  the 
  ground 
  at 
  

   Portage, 
  while 
  at 
  Mount 
  Morris 
  it 
  needs 
  to 
  be 
  brought 
  from 
  a 
  

   distance. 
  

  

  4) 
  The 
  Portage 
  site 
  affords 
  greater 
  waterpower 
  development. 
  

   With 
  the 
  Genesee 
  storage 
  dam 
  located 
  at 
  Mount 
  Morris 
  the 
  

   total 
  head 
  on 
  which 
  the 
  storage 
  can 
  be 
  applied 
  is 
  282 
  feet, 
  while 
  

   with 
  a 
  dam 
  at 
  Portage 
  the 
  total 
  head 
  on 
  which 
  the 
  stored 
  water 
  

   may 
  be 
  applied 
  is 
  782 
  feet. 
  

  

  5) 
  On 
  account 
  of 
  the 
  great 
  depth 
  of 
  the 
  foundation 
  at 
  Mount 
  

   Morris, 
  it 
  would 
  be 
  necessary 
  to 
  expend 
  over 
  f 
  1,000,000 
  before 
  the 
  

   dam 
  could 
  be 
  brought 
  to 
  the 
  level 
  of 
  the 
  present 
  water 
  surface. 
  

  

  The 
  proposed 
  regulation 
  of 
  Genesee 
  river 
  at 
  Portage 
  has 
  been 
  

   computed 
  on 
  the 
  basis 
  of 
  a 
  minimum 
  discharge 
  of 
  300 
  cubic 
  feet 
  

   per 
  second, 
  in 
  the 
  case 
  of 
  a 
  reservoir 
  storing 
  7,500,000,000 
  cubic 
  

   feet, 
  and 
  on 
  a 
  basis 
  of 
  a 
  minimum 
  of 
  457 
  cubic 
  feet 
  per 
  second 
  

   in 
  the 
  case 
  of 
  a 
  reservoir 
  storing 
  15,000,000,000 
  cubic 
  feet. 
  As 
  

   to 
  the 
  reason 
  for 
  fixing 
  upon 
  these 
  minimums, 
  in 
  river 
  regula- 
  

   tion 
  the 
  outflow 
  from 
  the 
  storage 
  reservoir 
  should 
  be 
  so 
  arranged 
  

   as 
  to 
  make 
  the 
  benefit 
  to 
  all 
  parts 
  of 
  the 
  stream 
  equal. 
  Es- 
  

   pecially 
  is 
  this 
  proposition 
  true 
  when, 
  as 
  in 
  the 
  present 
  case, 
  

   there 
  is 
  waterpower 
  distributed 
  throughout 
  the 
  whole 
  extent
