  designed 
  on 
  the 
  basis 
  of 
  giving 
  to 
  the 
  stream 
  at 
  least 
  0.5 
  inch 
  

   on 
  the 
  catchment 
  area 
  per 
  month. 
  1 
  With 
  0.45 
  cubic 
  foot 
  per 
  

   second 
  per 
  square 
  mile 
  always 
  flowing 
  away 
  from 
  the 
  controlled 
  

   catchment 
  area, 
  the 
  natural 
  flow 
  of 
  the 
  unregulated 
  portion 
  will 
  

   usually 
  furnish 
  an 
  additional 
  amount 
  sufficient 
  to 
  keep 
  the 
  river, 
  

   during 
  the 
  storage 
  period, 
  up 
  to 
  nearly 
  the 
  assumed 
  4500 
  cubic 
  

   feet 
  per 
  second 
  at 
  Mechanicville 
  ; 
  or 
  in 
  case 
  of 
  extreme 
  low 
  water 
  

   in 
  winter 
  other 
  reservoirs 
  may 
  be 
  relied 
  upon 
  to 
  assist 
  in 
  the 
  

   manner 
  already 
  pointed 
  out. 
  

  

  On 
  the 
  basis 
  of 
  12 
  to 
  14 
  inches 
  available 
  storage, 
  there 
  may 
  be, 
  

   with 
  0.5 
  inch 
  per 
  month 
  always 
  going 
  to 
  the 
  stream, 
  a 
  possible 
  

   total 
  requirement 
  for 
  the 
  year 
  of 
  from 
  15 
  to 
  18 
  inches. 
  

  

  Table 
  No. 
  61 
  shows 
  that 
  the 
  total 
  flow 
  for 
  the 
  year 
  1895 
  was 
  

   only 
  17.46 
  inches, 
  or 
  in 
  that 
  year 
  there 
  might 
  have 
  been 
  a 
  shortage, 
  

   if 
  the 
  reservoir 
  system 
  had 
  been 
  in 
  operation, 
  of 
  perhaps 
  0.5 
  inch. 
  

   Any 
  such 
  shortage 
  would 
  necessarily 
  have 
  been 
  carried 
  over 
  

   from 
  the 
  year 
  1894, 
  when, 
  in 
  November, 
  there 
  was 
  a 
  runoff 
  of 
  

   1.58 
  inches. 
  Allowing 
  0.5 
  inch 
  to 
  the 
  stream 
  from 
  the 
  November 
  

   rainfall 
  alone 
  there 
  would 
  have 
  been 
  1.08 
  inches 
  remaining 
  in 
  

   the 
  reservoirs 
  to 
  be 
  carried 
  over 
  to 
  1895. 
  

  

  Summary 
  of 
  Hudson 
  river 
  reservoirs. 
  In 
  conclusion, 
  it 
  may 
  be 
  

   said 
  that 
  it 
  is 
  entirely 
  feasible 
  to 
  construct 
  a 
  system 
  of 
  reser- 
  

   voirs 
  in 
  the 
  upper 
  Hudson 
  valley, 
  and 
  such 
  system 
  may 
  be 
  

   designed 
  with 
  reference 
  to 
  the 
  full 
  capacity 
  storage 
  of 
  at 
  least 
  

   1300 
  square 
  miles 
  of 
  area, 
  or 
  47 
  per 
  cent 
  of 
  the 
  total 
  area 
  above 
  

   Glens 
  Falls. 
  Such 
  control 
  would 
  result 
  in 
  the 
  material 
  reduc- 
  

   tion 
  of 
  floods 
  at 
  Glens 
  Falls 
  and 
  other 
  points. 
  

  

  The 
  proposed 
  total 
  storage 
  of 
  45,593,000,000 
  cubic 
  feet 
  would 
  

   maintain 
  4500 
  cubic 
  feet 
  per 
  second 
  flow, 
  as 
  well 
  as 
  supply 
  the 
  

   other 
  necessary 
  demands, 
  in 
  the 
  driest 
  season 
  of 
  the 
  gaging 
  

   period. 
  The 
  discharge 
  measurements 
  show 
  that 
  whereas 
  the 
  

   minimum 
  unregulated 
  flow 
  at 
  Glens 
  Falls 
  is 
  as 
  low 
  as 
  700 
  cubic 
  

   feet 
  per 
  second 
  for 
  a 
  monthly 
  mean, 
  with 
  the 
  storage 
  carried 
  out, 
  

   the 
  probable 
  monthly 
  mean 
  flow 
  at 
  Glens 
  Falls 
  will 
  be 
  at 
  least 
  

   3000 
  to 
  3600 
  cubic 
  feet 
  per 
  second. 
  The 
  minimum 
  regulated 
  flow 
  

   of 
  4500 
  cubic 
  feet 
  per 
  second 
  at 
  Mechanicville 
  will 
  increase 
  the 
  

   low-water 
  depth 
  in 
  the 
  Hudson 
  river 
  at 
  Albany 
  about 
  1.5 
  feet. 
  

  

  lr 
  This 
  is 
  the 
  same 
  basis 
  as 
  discussed 
  on 
  a 
  preceding 
  page 
  for 
  Salmon 
  river 
  

   reservoir. 
  0.5 
  inch 
  per 
  month 
  is 
  0.45 
  cubic 
  foot 
  per 
  second 
  per 
  square 
  mile.
