  The 
  coefficients 
  derived 
  from 
  Cornell 
  University 
  experiment 
  No. 
  

   14 
  have 
  been 
  used 
  in 
  computing 
  the 
  flow 
  over 
  this 
  dam. 
  The 
  flow 
  

   of 
  Oriskany 
  creek 
  represents 
  the 
  natural 
  runoff 
  of 
  the 
  tributary 
  

   catchment 
  modified 
  by 
  pond 
  storage, 
  with 
  additional 
  flow 
  during 
  

   the 
  summer 
  months 
  due 
  to 
  diversion 
  from 
  storage 
  reservoirs 
  on 
  the 
  

   Chenango 
  river 
  catchment, 
  through 
  the 
  summit 
  level 
  of 
  the 
  aban- 
  

   doned 
  Chenango 
  canal, 
  into 
  Oriskany 
  creek. 
  The 
  natural 
  catch- 
  

   ment 
  area 
  above 
  the 
  gaging 
  station 
  is 
  144 
  square 
  miles, 
  while 
  that 
  

   of 
  the 
  Chenango 
  river, 
  made 
  partially 
  tributary 
  through 
  Chenango 
  

   canal, 
  is 
  87 
  square 
  miles. 
  The 
  effective 
  catchment 
  area 
  during 
  

   the 
  navigation 
  season 
  is 
  therefore 
  231 
  square 
  miles, 
  while 
  the 
  

   effective 
  catchment 
  area 
  with 
  canals 
  closed 
  is 
  144 
  square 
  miles, 
  

   less 
  the 
  storage 
  of 
  the 
  several 
  reservoirs. 
  These 
  reservoirs 
  are 
  

   situated 
  in 
  Madison, 
  Eaton, 
  Nelson 
  and 
  Lebanon 
  townships 
  in 
  

   Madison 
  county, 
  and 
  include 
  Hatch 
  lake, 
  Eaton 
  brook, 
  Bradley 
  

   brook, 
  Leland 
  pond, 
  Madison 
  brook 
  and 
  Kingsley 
  brook 
  reservoirs. 
  

   Their 
  main 
  characteristics 
  and 
  storage 
  capacity 
  in 
  cubic 
  feet 
  are

  In 
  examining 
  tables 
  Nos. 
  76 
  and 
  77 
  it 
  will 
  be 
  seen 
  that 
  the 
  runoff 
  

   of 
  Oriskany 
  creek 
  is 
  considerably 
  larger 
  than 
  the 
  adjacent 
  Sau- 
  

   quoit 
  creek, 
  but 
  on 
  making 
  the 
  proper 
  deductions 
  for 
  these 
  reser- 
  

   voirs 
  the 
  two 
  will 
  be 
  found 
  to 
  be 
  substantially 
  the 
  same. 
  

  

  Geologically 
  this 
  stream 
  lies 
  in 
  the 
  horizon 
  of 
  the 
  Hamilton 
  

   shales, 
  crossing 
  the 
  Helderberg 
  and 
  Salina 
  groups.
