   For 
  several

  of 
  August 
  to 
  October, 
  1891, 
  

   the 
  flow 
  of

  was

  to 
  about 
  4.2

  As 
  a 
  general 
  proposition, 
  statements 
  of 
  minimum 
  flows 
  of 
  

   streams 
  ought 
  not 
  to 
  be 
  based 
  on 
  the 
  records 
  of 
  single 
  days, 
  

   specially 
  on 
  streams 
  where 
  there 
  are 
  mill 
  ponds 
  above 
  the 
  point 
  

   of 
  measurement, 
  because 
  such 
  accidental 
  circumstances 
  as 
  the 
  

   holding 
  back 
  of 
  the 
  water 
  may 
  vitiate 
  the 
  result; 
  from 
  this 
  point 
  

   of 
  view 
  an 
  average 
  extending 
  over 
  as 
  long 
  a 
  period 
  as 
  possible 
  

   should 
  be 
  taken. 
  

  

  The 
  measurements 
  of 
  Oatka 
  creek 
  from 
  August 
  to 
  October, 
  1891,. 
  

   illustrate 
  well 
  the 
  nearly 
  universal 
  tendency 
  of 
  streams 
  to 
  run 
  

   either 
  at 
  approximately 
  a 
  fixed 
  rate 
  or 
  to 
  decrease 
  only 
  very 
  

   slowly 
  after 
  the 
  tributary 
  ground 
  water 
  has 
  become 
  well 
  drawn 
  

   down. 
  For 
  several 
  days 
  at 
  a 
  time 
  the 
  records 
  show 
  only 
  slight 
  

   variation.

  The 
  result 
  of 
  a 
  measurement 
  of 
  

   Morris 
  run, 
  a 
  tributary 
  of 
  Oatka 
  creek, 
  the 
  source 
  of 
  a 
  part 
  of 
  the 
  

   water 
  supply 
  of 
  the 
  village 
  of 
  Warsaw, 
  Wyoming 
  county, 
  made 
  

   from 
  July 
  4 
  to 
  December 
  26, 
  1894, 
  is 
  shown 
  by 
  table 
  No. 
  82. 
  The 
  

   measured 
  catchment 
  area 
  is 
  156 
  acres, 
  but 
  it 
  may, 
  by 
  reason 
  of 
  the 
  

   peculiar 
  topography 
  be 
  somewhat 
  greater 
  than 
  this. 
  The 
  water 
  

   issues 
  along 
  the 
  thread 
  of 
  the 
  short 
  valley 
  in 
  the 
  form 
  of 
  springs) 
  

   The 
  measurement 
  was 
  made 
  by 
  a 
  thin-edged 
  notched 
  weir 
  at 
  a 
  

   point 
  just 
  below 
  the 
  lowest 
  spring. 
  As 
  may 
  be 
  observed, 
  the 
  flow 
  

   varied 
  greatly 
  at 
  different 
  times, 
  the 
  minimum 
  being 
  77,630 
  gal- 
  

   lons 
  per 
  day 
  or 
  7.2 
  cubic 
  feet 
  per 
  minute, 
  in 
  October. 
  On 
  July 
  8 
  

   the 
  discharge 
  was 
  238,580 
  gallons, 
  or 
  22.1 
  cubic 
  feet 
  per 
  minute 
  

   for 
  twenty-four 
  hours. 
  There 
  is 
  a 
  popular 
  impression 
  that 
  

   springs 
  do 
  not 
  vary 
  their 
  flow 
  at 
  different 
  seasons.
