  The 
  catchment 
  area 
  of 
  Sauquoit 
  creek 
  above 
  its 
  mouth 
  is 
  67 
  

   square 
  miles. 
  

  

  Oriskany 
  creek. 
  This 
  stream 
  rises 
  in 
  the 
  northern 
  part 
  of 
  Mad- 
  

   ison 
  county, 
  flowing 
  northerly 
  across 
  Oneida 
  county 
  into 
  the 
  

   Mohawk 
  river 
  at 
  Oriskany. 
  The 
  catchment 
  area 
  above 
  its 
  mouth 
  

   is 
  146 
  square 
  miles. 
  There 
  is 
  considerable 
  water 
  power 
  developed 
  

   on 
  Oriskany 
  creek. 
  

  

  Comparison

  the

  over 
  ti&o 
  dams 
  on 
  Oriskany 
  creek. 
  This 
  

   <;reek 
  is 
  of 
  slight 
  interest 
  because, 
  in 
  connection 
  with 
  the 
  work 
  

   done 
  for 
  the 
  Board 
  of 
  Engineers 
  on 
  Deep 
  Waterways, 
  two 
  gaging 
  

   stations 
  were 
  established 
  at 
  widely 
  varying 
  types 
  of 
  dams 
  and 
  it 
  

   was 
  found 
  that 
  even 
  in 
  winter 
  fairly 
  comparable 
  "results 
  could 
  be 
  

   obtained 
  by 
  gagings 
  over 
  such 
  dams. 
  The 
  first 
  station 
  was 
  estab- 
  

   lished 
  at 
  the 
  State 
  dam 
  at 
  Oriskany, 
  where 
  water 
  is 
  diverted 
  for 
  

   the 
  use 
  of 
  the 
  Erie 
  canal. 
  The 
  catchment 
  area 
  at 
  this 
  point 
  is 
  141 
  

   square 
  miles. 
  During 
  the 
  navigation 
  months, 
  a 
  record 
  was 
  kept 
  

   of 
  the 
  gate 
  openings, 
  together 
  with 
  daily 
  observations 
  of 
  the 
  differ- 
  

   once 
  in 
  water 
  surface 
  above 
  and 
  below 
  gates. 
  Outside 
  of 
  the 
  

   navigation 
  months, 
  the 
  feeder 
  gates 
  were 
  entirely 
  closed 
  and 
  the 
  

   record 
  is 
  for 
  flow 
  over 
  the 
  dam 
  only. 
  The 
  second 
  station 
  was 
  

   established 
  at 
  Coleman, 
  a 
  couple 
  of 
  miles 
  above 
  the 
  first, 
  where 
  

   the 
  catchment 
  area 
  is 
  141 
  square 
  miles. 
  

  

  The 
  object 
  of 
  establishing 
  two 
  stations 
  on 
  Oriskany 
  creek 
  was 
  

   to 
  determine 
  whether 
  on 
  dams 
  of 
  somewhat 
  different 
  forms, 
  but 
  

   with 
  nearly 
  the 
  same 
  catchment 
  area, 
  the 
  flows 
  could 
  be 
  gaged 
  

   olose 
  enough 
  to 
  give 
  comparable 
  figures. 
  Space 
  will 
  not 
  be 
  taken 
  

   to 
  give 
  the 
  method 
  of 
  computation 
  used 
  in 
  detail, 
  but 
  those 
  inter- 
  

   ested 
  can 
  refer 
  to 
  the 
  report 
  to 
  the 
  Board 
  of 
  Engineers 
  on 
  Deep 
  

   Waterways 
  for 
  an 
  extended 
  account 
  of 
  the 
  method 
  used. 
  For 
  

   present 
  purposes 
  it 
  is 
  sufficient 
  to 
  refer 
  to 
  the 
  accompanying 
  tabu- 
  

   lation, 
  in 
  which 
  are 
  given 
  the 
  flows 
  at 
  the 
  two 
  stations 
  for 
  the 
  

   months 
  from 
  October, 
  1898, 
  to 
  February, 
  1899, 
  inclusive. 
  During 
  

   the 
  winter 
  months, 
  December 
  to 
  February, 
  the 
  ice 
  was 
  kept 
  clear 
  

   from 
  the 
  crest 
  of 
  both 
  dams. 
  The 
  results 
  show 
  good 
  agreement 
  

   and 
  indicate 
  that 
  even 
  when 
  one 
  of 
  the 
  cases 
  is 
  complicated 
  by 
  

   discharge 
  through 
  a 
  number 
  of 
  water 
  wheels, 
  as 
  at 
  the 
  second
