  Minimum 
  flow 
  of 
  Black 
  river. 
  The 
  catchment 
  area 
  of 
  this 
  

   stream 
  at 
  Huntingtonville 
  dam, 
  where 
  the 
  measurements 
  are 
  

   made, 
  is 
  1889 
  square 
  miles. 
  Previous 
  to 
  1897, 
  aside 
  from 
  measure- 
  

   ments 
  made 
  by 
  engineers 
  in 
  the 
  employ 
  of 
  the 
  State 
  at 
  the 
  time 
  

   of 
  construction 
  of 
  the 
  Black 
  river 
  canal 
  and 
  a 
  few 
  made 
  by 
  Frank 
  

   A. 
  Hines 
  in 
  1875, 
  there 
  had 
  been 
  no 
  measurements 
  taken 
  of 
  the 
  

   flow. 
  In 
  February, 
  1897, 
  the 
  Board 
  of 
  Water 
  Commissioners 
  of 
  

   Watertown 
  began 
  a 
  record 
  of 
  the 
  daily 
  flow 
  of 
  the 
  river, 
  from 
  

   which 
  the 
  following 
  statements 
  of 
  minimum 
  flows 
  are 
  taken. 
  

  

  In 
  July, 
  1897, 
  the 
  mean 
  flow 
  for 
  the 
  entire 
  month 
  was 
  940' 
  cubic- 
  

   feet 
  per 
  second; 
  for 
  two 
  days 
  it 
  was 
  about 
  582 
  cubic 
  feet 
  per 
  

   second; 
  one 
  day, 
  630 
  cubic 
  feet 
  per 
  second, 
  and 
  one 
  Sunday 
  is 
  

   given 
  at 
  480 
  cubic 
  feet 
  per 
  second. 
  In 
  August, 
  1897, 
  the 
  mean 
  

   flow 
  for 
  August 
  6 
  was 
  782 
  cubic 
  feet 
  per 
  second; 
  for 
  August 
  7, 
  

   630 
  cubic 
  feet 
  per 
  second; 
  August 
  8 
  (Sunday), 
  362 
  cubic 
  feet 
  per 
  

   second; 
  August 
  9, 
  536 
  cubic 
  feet 
  per 
  second; 
  August 
  10, 
  630 
  

   cubic 
  feet 
  per 
  second; 
  August 
  25, 
  522 
  cubic 
  feet 
  per 
  second; 
  

   August 
  26, 
  566 
  cubic 
  feet 
  per 
  second; 
  August 
  27, 
  582 
  cubic 
  feet 
  

   per 
  second, 
  and 
  August 
  28, 
  322 
  cubic 
  feet 
  per 
  second. 
  

  

  In 
  1898 
  the 
  minimum 
  month 
  was 
  July, 
  in 
  which 
  the 
  mean 
  flow 
  

   was 
  1128 
  cubic 
  feet 
  per 
  second, 
  although 
  for 
  five 
  days 
  in 
  August 
  

   the 
  flow 
  was 
  about 
  900 
  cubic 
  feet 
  per 
  second. 
  

  

  The 
  mean 
  flow 
  for 
  the 
  month 
  of 
  August, 
  1899, 
  was 
  897 
  cubic 
  

   feet 
  per 
  second 
  and 
  for 
  September, 
  990 
  cubic 
  feet 
  per 
  second. 
  

   For 
  a 
  short 
  period 
  in 
  August 
  the 
  flow 
  fell 
  to 
  about 
  700 
  cubic 
  feet 
  

   per 
  second, 
  and 
  on 
  one 
  day 
  it 
  was 
  522 
  cubic 
  feet 
  per 
  second. 
  In 
  

   considering 
  these 
  statements 
  of 
  minimum 
  flow 
  in 
  Black 
  river, 
  the 
  

   fact 
  that 
  there 
  is 
  a 
  leakage 
  estimated 
  at 
  250 
  cubic 
  feet 
  per 
  second 
  

   should 
  be 
  taken 
  into 
  account; 
  520 
  cubic 
  feet 
  per 
  second, 
  which 
  

   with 
  one 
  exception 
  is 
  the 
  lowest, 
  is 
  at 
  the 
  rate 
  of 
  0.27 
  cubic 
  foot 
  

   per 
  second 
  per 
  square 
  mile. 
  The 
  daily 
  record 
  of 
  this 
  stream 
  

   shows 
  that 
  it 
  is 
  a 
  good 
  water 
  yielder, 
  as 
  indeed 
  might 
  be 
  expected. 
  

   There 
  are 
  a 
  large 
  number 
  of 
  reservoirs 
  at 
  the 
  headwaters 
  and 
  it 
  

   flows 
  from 
  an 
  area 
  largely 
  in 
  primeval 
  forest. 
  It 
  is 
  doubtful, 
  

   therefore, 
  if 
  Black 
  river 
  will, 
  while 
  present 
  forestry 
  conditions 
  

   are 
  maintained, 
  go 
  below 
  about 
  0.3 
  cubic 
  foot 
  per 
  second 
  per 
  

   square 
  mile 
  for 
  more 
  than 
  a 
  few 
  days 
  at 
  a 
  time, 
  although 
  it 
  is 
  

   claimed 
  to 
  have 
  been 
  less 
  than 
  this 
  for 
  some 
  time 
  in 
  1849.
