  Black 
  creek. 
  This 
  stream 
  flows 
  into 
  the 
  Genesee 
  river 
  on 
  the 
  

   west 
  side 
  at 
  a 
  point 
  about 
  four 
  miles 
  southwest 
  of 
  the 
  Mount 
  Hope 
  

   reservoir. 
  Its 
  catchment 
  area 
  is 
  so 
  large 
  that 
  there 
  could 
  be 
  no 
  

   question 
  as 
  to 
  the 
  sufficiency 
  of 
  the 
  stream 
  to 
  furnish 
  the 
  desired 
  

   amount 
  of 
  water. 
  The 
  quality 
  of 
  the 
  water 
  is, 
  however, 
  very 
  ob- 
  

   jectionable, 
  since 
  it 
  contains 
  73.4 
  grains 
  of 
  solid 
  matter 
  per 
  gal- 
  

   lon. 
  The 
  stream 
  also 
  flows 
  through 
  extensive 
  swampy 
  districts 
  

   so 
  that 
  filtering 
  would 
  be 
  indispensable 
  in 
  order 
  to 
  fit 
  the 
  water 
  

   for 
  domestic 
  use. 
  The 
  cost 
  of 
  the 
  necessary 
  filtering 
  and 
  pumping 
  

   plant, 
  with 
  force-main 
  to 
  the 
  reservoir, 
  would 
  amount 
  to 
  at 
  least 
  

   180,000. 
  

  

  Oatka 
  creek. 
  The 
  confluence 
  of 
  this 
  stream 
  with 
  the 
  Genesee 
  

   river 
  is 
  about 
  one 
  mile 
  east 
  of 
  Scottsville 
  and 
  a 
  little 
  more 
  than 
  

   nine 
  miles 
  in 
  a 
  direct 
  line 
  southwest 
  of 
  the 
  Mount 
  Hope 
  reservoir. 
  

   At 
  Scottsville 
  the 
  entire 
  dry 
  weather 
  flow 
  is 
  diverted 
  into 
  the 
  old 
  

   Genesee 
  valley 
  canal, 
  through 
  which 
  it 
  flows 
  to 
  the 
  southern 
  por- 
  

   tion 
  of 
  Rochester, 
  where 
  it 
  is 
  carried 
  in 
  a 
  pipe 
  under 
  the 
  river 
  into 
  

   the 
  Erie 
  canal 
  feeder. 
  During 
  the 
  season 
  of 
  navigation 
  on 
  Erie 
  

   canal 
  the 
  State 
  has 
  the 
  first 
  claim 
  upon 
  the 
  water, 
  and 
  it 
  was 
  con- 
  

   sidered 
  doubtful 
  whether 
  permission 
  to 
  use 
  any 
  portion 
  thereof 
  

   could 
  be 
  obtained. 
  Assuming, 
  however, 
  that 
  such 
  consent 
  was 
  ob- 
  

   tained, 
  it 
  would 
  not 
  be 
  advisable 
  to 
  use 
  the 
  water 
  for 
  drinking 
  pur- 
  

   poses 
  without 
  filtration, 
  as 
  the 
  creek 
  receives 
  considerable 
  sewage 
  

   from 
  the 
  villages 
  of 
  Warsaw 
  and 
  Leroy, 
  besides 
  the 
  waste 
  water 
  of 
  

   the 
  salt 
  works 
  in 
  the 
  Wyoming 
  valley 
  and 
  the 
  surface 
  drainage 
  

   from 
  Scottsville 
  and 
  a 
  number 
  of 
  other 
  small 
  villages. 
  

  

  The 
  suggestion 
  was 
  also 
  made 
  to 
  obtain 
  the 
  needed 
  temporary 
  

   supply 
  from 
  the 
  old 
  Genesee 
  valley 
  canal 
  within 
  the 
  city 
  limits, 
  

   it 
  being 
  taken 
  for 
  granted 
  that 
  permission 
  to 
  do 
  so 
  could 
  be 
  se- 
  

   cured 
  from 
  the 
  canal 
  authorities. 
  If 
  this 
  had 
  been 
  carried 
  out, 
  

   the 
  same 
  objection 
  to 
  the 
  use 
  of 
  the 
  water 
  without 
  filtration 
  would 
  

   likewise 
  be 
  valid, 
  and 
  might 
  even 
  become 
  stronger 
  when 
  it 
  is 
  re- 
  

   membered 
  that 
  in 
  many 
  places 
  between 
  Scottsville 
  and 
  Rochester 
  

   the 
  old 
  canal 
  prism 
  contains 
  dense 
  growths 
  of 
  aquatic 
  vegeta- 
  

   tion, 
  the 
  emanations 
  from 
  which 
  have 
  been 
  the 
  cause 
  of 
  much 
  

   complaint 
  from 
  persons 
  residing 
  in 
  the 
  vicinity. 
  This 
  vegetation, 
  

   furthermore, 
  greatly 
  retards 
  the 
  flow 
  of 
  the 
  water 
  ; 
  hence, 
  if 
  an 
  

   adequate 
  supply 
  for 
  both 
  the 
  Erie 
  canal 
  and 
  the 
  city 
  were 
  to 
  be
