  accompanying 
  taible 
  allowance 
  for 
  diversion 
  to 
  the 
  Oswego 
  canal, 
  

   which 
  is 
  also 
  supplied 
  from 
  this 
  dam, 
  has 
  not 
  been 
  made, 
  but 
  

   such 
  diversion 
  can 
  not 
  be 
  very 
  large 
  because 
  of 
  the 
  small 
  amount 
  

   of 
  business 
  on 
  that 
  canal 
  during 
  the 
  last 
  few 
  years. 
  

  

  Gagings 
  of 
  Oswego 
  river 
  above 
  Minetto 
  have 
  also 
  been 
  made 
  

   from 
  September, 
  1900, 
  to 
  date, 
  at 
  which 
  time 
  a 
  current 
  meter 
  

   station 
  was 
  established 
  at 
  this 
  point. 
  

  

  Gagings 
  were 
  also 
  begun 
  in 
  1898 
  at 
  the 
  upper 
  dam 
  at 
  Fulton, 
  

   which 
  is 
  a 
  well 
  j 
  built 
  stone 
  dam 
  and 
  has 
  no 
  leakage. 
  The 
  dam 
  is 
  

   404.6 
  feet 
  in 
  length, 
  with 
  a 
  crest 
  practically 
  level. 
  The 
  following 
  

   cut 
  shows 
  the 
  form 
  of 
  this 
  dam

  Geologically 
  the 
  Oswego 
  river 
  lies 
  in 
  the 
  horizon 
  of 
  the 
  Medina

  and 
  Clinton 
  groups. 
  

  

  Discharge 
  measurements 
  of 
  Seneca 
  river. 
  This 
  station 
  is 
  

   located 
  at 
  the 
  stone 
  dam 
  on 
  Seneca 
  river 
  at 
  Baldwinsville. 
  The 
  

   outlets 
  of 
  Otisco, 
  Skaneateles 
  and 
  Owasco 
  lakes, 
  tributaries 
  of 
  

   Seneca 
  river, 
  are 
  crossed 
  by 
  the 
  Erie 
  canal 
  and 
  a 
  portion 
  of 
  their 
  

   flow 
  intercepted 
  for 
  the 
  supply 
  of 
  this 
  canal. 
  The 
  chief 
  supply 
  

   for 
  the 
  Erie 
  canal 
  to 
  Montezuma 
  marsh 
  is 
  from 
  Lake 
  Erie 
  and 
  

   Lake 
  Erie 
  water 
  is 
  discharged 
  into 
  Seneca 
  river 
  and 
  thus 
  returned 
  

   through 
  the 
  Oswego 
  river 
  to 
  Lake 
  Ontario. 
  It 
  is 
  uncertain, 
  there- 
  

   fore, 
  whether 
  the 
  abstraction 
  from 
  Otisco, 
  Skaneateles 
  and 
  

   Owasco 
  lakes 
  is 
  very 
  material, 
  as 
  the 
  amount 
  discharged 
  in 
  Seneca 
  

   river 
  varies 
  and 
  has 
  never 
  been 
  closely 
  measured. 
  

  

  The 
  upper 
  reaches 
  of 
  Seneca 
  river 
  are 
  canalized, 
  forming 
  the 
  

   Cayuga 
  and 
  iSeneca 
  canal, 
  while 
  the 
  portion 
  below 
  Baldwinsville,
