  This

  has 
  a 
  catchment 
  

   area 
  of 
  190.5 
  square 
  miles 
  above 
  Henderson's 
  mill, 
  of 
  which 
  10 
  to 
  

   20 
  square 
  miles 
  are 
  flats, 
  the 
  balance 
  of 
  the 
  area 
  having 
  rather 
  

   sharp 
  slopes. 
  The 
  soil

   upper 
  part 
  of 
  the 
  catchment 
  is 
  mostly 
  primeval 
  forest. 
  

  

  Data 
  from 
  flood 
  hights 
  were 
  also

  at 
  Adams

  Ordinary 
  flood 
  -flows 
  in 
  this 
  stream 
  average 
  perhaps 
  

   35

  Floods 
  in 
  north 
  branch 
  of 
  Sandy 
  creek. 
  A 
  flood-flow 
  was 
  meas- 
  

   ured 
  in 
  this 
  stream 
  at 
  Adams

  the 
  winter 
  of 
  1897 
  of 
  7410 
  cubic 
  

   feet

  The 
  catchment 
  area 
  is 
  the 
  same

  that 
  of 
  the 
  

   south 
  branch 
  at 
  this 
  place, 
  or 
  110 
  square

  Hence, 
  the 
  flow 
  

   was 
  at 
  the 
  rate 
  of 
  67 
  cubic 
  feet 
  per 
  second 
  per
