  Delaware 
  River 
  System 
  

  

  Delaware 
  river. 
  The 
  main 
  Delaware 
  river 
  drains 
  the 
  western 
  

   slopes 
  of 
  the 
  Catskill 
  mountains, 
  originating 
  on 
  the 
  slope 
  of 
  Mine 
  

   mountain 
  near 
  the 
  southwestern 
  line 
  of 
  Schoharie 
  county. 
  It 
  

   flows 
  southwesterly 
  across 
  Delaware 
  county 
  to 
  Deposit, 
  where 
  it 
  

   is 
  joined 
  by 
  Oquaga 
  creek, 
  a 
  large 
  tributary 
  draining 
  eastern 
  

   Broome 
  county. 
  The 
  upper 
  catchment' 
  area 
  is 
  long 
  and 
  narrow, 
  

   with 
  numerous 
  short 
  lateral 
  tributaries. 
  It 
  is 
  precipitous 
  and 
  to 
  

   a, 
  considerable 
  extent 
  covered 
  with 
  a 
  not 
  very 
  dense 
  second-growth 
  

   forest. 
  At 
  Deposit 
  the 
  stream 
  turns 
  abruptly 
  to 
  the 
  southeast, 
  

   forming 
  the 
  boundary 
  line 
  between 
  New 
  York 
  and 
  Pennsylvania 
  

   until 
  Port 
  Jervis 
  is 
  reached. 
  At 
  this 
  point 
  it 
  encounters 
  the 
  foot 
  

   of 
  the 
  Shawangunk 
  range 
  and 
  its 
  direction 
  of 
  flow 
  is 
  again 
  turned 
  

   to 
  the 
  southwest. 
  It 
  leaves 
  New 
  York 
  State 
  at 
  this 
  point. 
  Above 
  

   Hancock 
  the 
  main 
  stream 
  is 
  known 
  as 
  the 
  West 
  branch 
  of 
  the 
  

   Delaware 
  river 
  in 
  order 
  to 
  distinguish 
  it 
  from 
  the 
  East 
  or 
  Pepac- 
  

   ton 
  branch 
  of 
  the 
  river. 
  It 
  is 
  also 
  sometimes 
  called 
  " 
  Mohawk," 
  

   but 
  should 
  not 
  be 
  confused 
  with 
  Mohawk 
  river, 
  a 
  tributary 
  of 
  the 
  

   Hudson.

  East 
  branch 
  or 
  Pepacton 
  river. 
  The 
  principal 
  tributary 
  of 
  Dela- 
  

   ware 
  river 
  in 
  New 
  York 
  State 
  is 
  the 
  East 
  branch 
  of 
  the 
  Delaware 
  

   or 
  Pepacton 
  river, 
  which 
  rises 
  in 
  the 
  eastern 
  part 
  of 
  Delaware 
  

   and 
  Greene 
  counties, 
  flowing 
  southwest 
  in 
  a 
  course 
  generally 
  

   parallel 
  to 
  the 
  main 
  stream. 
  The 
  catchment 
  area 
  is 
  broader 
  and 
  

   more 
  branching 
  than 
  in 
  the 
  case 
  of 
  the 
  West 
  branch. 
  Several 
  of 
  

   the 
  tributaries 
  head 
  in 
  small 
  lakes 
  and 
  ponds. 
  

  

  Neversink 
  river. 
  This 
  river 
  rises 
  in 
  the 
  foothills 
  of 
  the 
  Gatskill 
  

   mountains 
  in 
  the 
  southwestern 
  part 
  of 
  Ulster 
  county. 
  The 
  east 
  

   and 
  west 
  branches 
  unite 
  to 
  form 
  the 
  main 
  stream 
  near 
  the 
  south 
  

   line 
  of 
  Ulster 
  county, 
  from 
  which 
  point 
  the 
  main 
  stream 
  flows
