﻿HYDROLOGY 
  OF 
  NEW 
  YORK

  in 
  the 
  years 
  just 
  enumerated 
  were 
  specially 
  severe, 
  but 
  floods 
  not 
  

   so 
  severe, 
  yet 
  doing 
  considerable 
  damage, 
  have 
  occurred 
  in 
  several 
  

   of 
  the 
  intervening 
  years. 
  

  

  2) 
  Water 
  would 
  be 
  supplied 
  for 
  the 
  enlarged 
  Erie 
  canal. 
  

   According 
  to 
  Mr 
  Bogart's 
  report 
  of 
  1890, 
  there 
  should 
  have 
  been 
  

   provided 
  a 
  storage 
  on 
  Genesee 
  river 
  of 
  1,500,000,000 
  cubic 
  feet 
  

   for 
  the 
  purpose 
  of 
  supplying 
  Erie 
  canal 
  as 
  it 
  existed 
  at 
  that 
  date. 
  

  

  3) 
  The 
  agricultural 
  production 
  of 
  the 
  broad 
  level 
  area 
  in- 
  

   cluded 
  in 
  the 
  Genesee 
  valley 
  between 
  Rochester, 
  Mount 
  Morris 
  and 
  

   Dansville, 
  estimated 
  at 
  from 
  60 
  to 
  80 
  square 
  miles, 
  might 
  be 
  

   greatly 
  increased 
  by 
  moderate 
  irrigation 
  if 
  the 
  flood 
  contingency 
  

   was 
  removed 
  and 
  the 
  proper 
  irrigation 
  channels 
  were 
  "constructed. 
  

  

  4) 
  Considerable 
  sanitary 
  benefit 
  would 
  result 
  from 
  the 
  increased 
  

   flow 
  during 
  the 
  low-water 
  period 
  through 
  the 
  proposed 
  regu- 
  

   lation. 
  The 
  entire 
  sewage 
  at 
  Rochester, 
  a 
  city 
  of 
  175,000 
  

   inhabitants, 
  now 
  passes 
  into 
  Genesee 
  river. 
  The 
  channel 
  of 
  this 
  

   stream, 
  beween 
  the 
  foot 
  of 
  the 
  lower 
  falls 
  at 
  Rochester 
  and 
  

   Lake 
  Ontario, 
  is 
  so 
  broad 
  and 
  deep 
  that 
  during 
  the 
  time 
  of 
  ex- 
  

   treme 
  low 
  water 
  in 
  the 
  summer 
  and 
  fall 
  the 
  current 
  is 
  scarcely 
  

   perceptible. 
  The 
  sewage 
  of 
  the 
  city 
  therefore 
  lodges 
  in 
  this 
  sec- 
  

   tion, 
  producing 
  a 
  serious 
  nuisance. 
  The 
  regulation 
  of 
  the 
  river, 
  

   by 
  preventing 
  floods, 
  would 
  also 
  improve 
  the 
  sanitary 
  condition 
  

   of 
  the 
  broad 
  upper 
  valley, 
  where 
  the 
  annual 
  overflow 
  has 
  been 
  

   shown 
  to 
  cause 
  more 
  or 
  less 
  sickness. 
  

  

  5) 
  The 
  waterpower 
  would 
  be 
  increased. 
  Wheels 
  are 
  now 
  set 
  

   on 
  the 
  Genesee 
  river 
  capable 
  of 
  producing, 
  at 
  the 
  manufacturers' 
  

   rating, 
  about 
  20,000 
  net 
  horsepower, 
  while 
  the 
  low-water 
  flow 
  of 
  

   the 
  stream 
  does 
  mot 
  exceed 
  about 
  5000 
  net 
  horsepower. 
  

  

  In 
  summation 
  of 
  the 
  preceding 
  points 
  it 
  may 
  be 
  urged, 
  in 
  gen- 
  

   eral, 
  that 
  in 
  constructing 
  the 
  proposed 
  Genesee 
  storage 
  dam, 
  in 
  

   addition 
  to 
  the 
  private 
  interests 
  to 
  be 
  conserved, 
  public 
  service 
  of 
  

   an 
  extended 
  character 
  would 
  be 
  performed. 
  

  

  Mount 
  Morris 
  site. 
  Referring 
  to 
  Mr 
  Bogart's 
  report 
  of 
  1890, 
  

   it 
  is 
  learned 
  that 
  the 
  investigations 
  of 
  that 
  year 
  were 
  general 
  in 
  

   their 
  character. 
  The 
  work 
  was 
  carried 
  on 
  more 
  particularly 
  with 
  

   reference 
  to 
  a 
  location 
  in 
  the 
  Genesee 
  river 
  gorge, 
  between 
  Mount 
  

   Morris 
  and 
  the 
  foot 
  of 
  the 
  Portage 
  falls. 
  No 
  detailed 
  surveys 
  

   were 
  made 
  further 
  than 
  necessary 
  to 
  make 
  a 
  general 
  estimate 
  of 
  

   the 
  cost 
  of 
  a 
  dam 
  58 
  feet 
  in 
  hight, 
  which 
  would 
  store 
  1,500,000,000
