  Floods

  Owing 
  to 
  the 
  regulating 
  effect 
  of 
  

   Schroon 
  lake, 
  serious 
  floods 
  are 
  unknown 
  in 
  this 
  stream. 
  The 
  

   usual 
  extreme 
  flows 
  are 
  about 
  8000 
  cubic 
  feet

  In 
  1892 
  the 
  Mohawk 
  at 
  Kexford 
  Flats 
  flowed 
  at 
  the 
  rate 
  of 
  

   78.350 
  cubic 
  feet 
  per 
  second 
  (catchment,

  feet

  On 
  February 
  14, 
  1900, 
  the 
  

   flow 
  here 
  was 
  45,000 
  cubic

  per

  or 
  at 
  the 
  rate 
  of 
  14

  Ordinary 
  floods 
  at 
  this 
  

   place 
  are 
  from 
  30,000 
  to 
  35,000 
  cubic

  The 
  maximum 
  discharge

  the 
  river 
  at

  was 
  in 
  

   March, 
  1901, 
  and 
  is 
  estimated 
  to 
  have 
  been 
  23,150
