   which 
  time 
  a

  Floods 
  in 
  Osicego 
  river. 
  The 
  highest 
  water 
  reported 
  in 
  Oswego 
  

   river 
  is 
  a 
  depth 
  of 
  4 
  feet 
  on 
  the 
  crest 
  of 
  the 
  dam 
  at 
  Fulton, 
  the 
  

   flow 
  being 
  19,500 
  cubic 
  feet 
  per 
  second, 
  the 
  ordinary 
  spring 
  flood 
  

   amounting 
  to 
  17,700 
  cubic 
  feet 
  per 
  second. 
  This 
  figure 
  is 
  verified 
  

   by 
  the 
  statement 
  of 
  the 
  late 
  Charles 
  Rhodes, 
  Esq. 
  of 
  the 
  Oswego 
  

   Canal 
  Company, 
  who 
  studied 
  Oswego 
  river 
  extensively 
  and 
  who, 
  

   according 
  to 
  the 
  Report 
  on 
  Water 
  Power 
  of 
  the 
  United 
  States 
  in 
  

   the 
  Tenth 
  Census, 
  considered 
  that 
  the 
  ordinary 
  flood 
  discharge 
  at 
  

   Oswego 
  was 
  from 
  16,000 
  to 
  17,000 
  cubic 
  feet 
  per 
  second, 
  and 
  that 
  

   an 
  excessive 
  flood 
  might 
  be 
  as 
  large 
  as 
  41,000 
  to 
  42,000 
  cubic 
  feet 
  

   per 
  second, 
  these 
  latter 
  figures 
  probably 
  being 
  the 
  discharge 
  of 
  the 
  

   Oswego 
  river 
  in 
  the 
  great 
  flood 
  of 
  March, 
  186&. 
  Thus 
  far 
  exact 
  

   figures 
  have 
  not 
  been 
  obtained 
  of 
  any 
  flood 
  exceeding 
  about 
  21,000 
  

   cubic 
  feet 
  per 
  second. 
  This 
  flow 
  when 
  computed 
  in 
  cubic 
  feet 
  per 
  

   second 
  per 
  square 
  mile 
  does 
  not 
  much 
  exceed 
  4 
  cubic 
  feet, 
  which 
  is 
  

   very 
  small. 
  

  

  The 
  catchment 
  area 
  of 
  Oswego 
  river 
  at 
  Oswego 
  is 
  5002 
  square 
  

   miles, 
  and 
  a 
  very 
  interesting 
  question 
  arises 
  as 
  to 
  why 
  a 
  stream 
  

   with 
  so 
  large 
  an 
  area 
  as 
  this, 
  issuing 
  from 
  a 
  region 
  with 
  a 
  mean 
  

   annual 
  rainfall 
  of 
  from 
  about 
  30 
  to 
  40 
  inches 
  and 
  with 
  heavy 
  snow- 
  

   fall, 
  frequently 
  melting 
  suddenly 
  at 
  the 
  end 
  of 
  winter, 
  should 
  

   not 
  show 
  greater 
  flood-flows 
  than 
  a 
  maximum 
  of 
  about 
  4 
  to 
  8 
  cubic 
  

   feet 
  per 
  second 
  per 
  square 
  mile. 
  The 
  answer 
  to 
  this 
  may 
  be 
  

   found 
  in 
  considering 
  the 
  large 
  temporary 
  storage 
  on 
  the 
  surfaces 
  

   of 
  the 
  lakes, 
  marshes 
  and 
  flat 
  valleys 
  of 
  Oswego 
  basin, 
  as 
  shown 
  

   by 
  the 
  tabulation 
  on

  Floods 
  in 
  Seneca 
  river. 
  According 
  to 
  statements 
  made 
  by 
  

   people 
  at 
  Baldwinsville, 
  mill 
  owners 
  and 
  others, 
  ordinary 
  high 
  

   water 
  in 
  Seneca 
  river 
  is 
  about 
  3 
  feet 
  on 
  the 
  crest 
  of 
  the 
  dam 
  

   there 
  and 
  occurs 
  nearly 
  every 
  spring.
