  The 
  small 
  hamlet 
  of 
  Redfield 
  is 
  the 
  only 
  village 
  within 
  the 
  area 
  

   to 
  be 
  flooded. 
  The 
  lands 
  to 
  be 
  taken 
  include 
  a 
  considerable 
  pro- 
  

   portion 
  of 
  swamp 
  and 
  timber 
  area, 
  from 
  which 
  the 
  valuable 
  

   timber 
  has 
  been 
  mostly 
  cut. 
  The 
  balance 
  of 
  the 
  area 
  is 
  not 
  

   valuable, 
  and 
  this 
  reservoir, 
  as 
  a 
  whole, 
  is 
  considered 
  to 
  present 
  

   favorable 
  conditions 
  for 
  taking 
  such 
  an 
  area. 
  There 
  is 
  one 
  ceme- 
  

   tery 
  to 
  be 
  removed 
  at 
  Redfield. 
  

  

  In 
  the 
  Report 
  of 
  the 
  State 
  Engineer 
  and 
  Surveyor 
  for 
  1895 
  it 
  

   is 
  shown 
  in 
  the 
  report 
  of 
  the 
  upper 
  Hudson 
  storage 
  surveys 
  that 
  

   reservoirs 
  for 
  storing 
  water 
  in 
  the 
  Adirondack 
  region 
  may 
  be 
  

   developed 
  up 
  to 
  a 
  storage 
  of 
  13.5 
  inches 
  on 
  the 
  tributary 
  catch- 
  

   ment 
  area 
  for 
  a 
  runoff 
  like 
  that 
  of 
  Hudson 
  river. 
  Since 
  meteoro- 
  

   logical 
  conditions 
  on 
  the 
  Salmon 
  river 
  are 
  substantially 
  the 
  same 
  

   as 
  on 
  the 
  Hudson, 
  there 
  is 
  no 
  reason 
  why 
  the 
  argument 
  made 
  in 
  

   the 
  Hudson 
  storage 
  report 
  may 
  not 
  apply 
  here. 
  Taking, 
  then, 
  the 
  

   Hudson 
  report 
  as 
  a 
  part 
  of 
  this 
  discussion, 
  so 
  far 
  as 
  necessary 
  

   to 
  cover 
  the 
  argument 
  for 
  reservoirs 
  developing 
  a 
  storage 
  of 
  13.5 
  

   inches 
  on 
  a 
  catchment 
  area 
  subject 
  to 
  a 
  runoff 
  like 
  that 
  of 
  the 
  

   northern 
  plateau 
  of 
  New 
  York, 
  we 
  may 
  state 
  the 
  general 
  problem 
  

   in 
  this 
  way 
  : 
  Having 
  a 
  reservoir 
  of 
  a 
  given 
  area 
  and 
  volume, 
  

   with 
  a 
  tributary 
  catchment 
  area 
  of 
  190.5 
  square 
  miles, 
  it 
  is 
  re- 
  

   quired 
  to 
  find 
  how 
  much 
  water 
  can 
  be 
  reasonably 
  expected 
  to 
  be 
  

   collected 
  from 
  the 
  catchment, 
  stored 
  in 
  the 
  reservoir, 
  and 
  drawn 
  

   from 
  it 
  during 
  a 
  dry 
  year, 
  or 
  during 
  a 
  series 
  of 
  such 
  years. 
  

  

  The 
  water 
  collected 
  and 
  stored 
  in 
  the 
  Salmon 
  river 
  reservoir 
  

   during 
  the 
  entire 
  year 
  may 
  be 
  drawn 
  from 
  it 
  in 
  three 
  ways, 
  as 
  

   follows 
  : 
  

  

  1) 
  By 
  evaporation 
  from 
  the 
  surface 
  of 
  the 
  reservoir. 
  

  

  2) 
  By 
  supplying 
  a 
  certain 
  fixed 
  quantity 
  to 
  Salmon 
  river 
  below 
  

   the 
  dam 
  during 
  the 
  entire 
  year. 
  

  

  3) 
  By 
  feeding 
  the 
  canal 
  during 
  the 
  months 
  of 
  May, 
  June, 
  July, 
  

   August, 
  September, 
  October 
  and 
  November. 
  

  

  There 
  will 
  also 
  be 
  a 
  slight 
  outgo 
  by 
  percolation, 
  leakage, 
  etc. 
  

   which 
  may 
  be 
  neglected 
  here. 
  

  

  The 
  catchment 
  areas 
  of 
  the 
  Salmon 
  river 
  and 
  the 
  upper 
  Hudson 
  

   being 
  of 
  the 
  same 
  general 
  character 
  as 
  regards 
  proportion 
  of 
  for- 
  

   ests 
  and 
  annual 
  rainfall, 
  it 
  is 
  reasonable 
  to 
  estimate 
  that 
  the 
  run- 
  

   offs 
  from 
  the 
  two 
  streams 
  will 
  be 
  substantially 
  equal; 
  hence, 
  the
