  furnished 
  by 
  the 
  old 
  canal, 
  the 
  channel 
  would 
  have 
  to 
  be 
  thoroughly 
  

   cleared 
  out 
  for 
  a 
  distance 
  of 
  several 
  miles 
  and 
  maintained 
  in 
  this 
  

   condition. 
  The 
  cost 
  of 
  such 
  an 
  undertaking, 
  in 
  addition 
  to 
  the 
  

   necessary 
  expense 
  of 
  filtering 
  the 
  water, 
  rendered 
  this 
  source 
  

   undesirable. 
  

  

  Caledonia 
  springs. 
  These 
  springs 
  are 
  nineteen 
  miles 
  southwest 
  

   of 
  Rochester 
  and 
  have 
  a 
  flow 
  of 
  from 
  2,000,000 
  to 
  4,000,000 
  gallons 
  

   per 
  day. 
  A 
  considerable 
  length 
  of 
  the 
  outlet 
  is 
  now 
  used 
  by 
  the 
  

   State 
  Fish 
  Commissioners 
  for 
  hatching 
  purposes', 
  so 
  that 
  if 
  the 
  

   water 
  had 
  been 
  taken 
  by 
  the 
  city, 
  the 
  intake 
  would 
  doubtless 
  

   have 
  had 
  to 
  be 
  located 
  below 
  the 
  hatching 
  station. 
  Such 
  a 
  loca- 
  

   tion 
  would 
  have 
  been 
  undesirable 
  unless 
  the 
  water 
  were 
  filtered. 
  

   In 
  regard 
  to 
  elevation, 
  Mr 
  Marsh 
  stated 
  that 
  this 
  water 
  could 
  be 
  

   conveyed 
  to 
  the 
  city 
  in 
  pipes, 
  but, 
  on 
  account 
  of 
  the 
  distance, 
  not 
  

   at 
  a 
  hight 
  sufficient 
  for 
  distribution 
  by 
  gravity. 
  A 
  pumping 
  sta- 
  

   tion 
  would 
  therefore 
  have 
  been 
  required 
  in 
  this 
  case 
  also 
  and 
  the 
  

   expense 
  of 
  constructing 
  the 
  works 
  was 
  estimated 
  at 
  more 
  than 
  

   f 
  200,000, 
  exclusive 
  of 
  the 
  filters. 
  The 
  permanent 
  hardness 
  of 
  the 
  

   Caledonia 
  springs 
  is 
  stated 
  at 
  about 
  70 
  parts 
  per 
  100,000. 
  Their 
  

   source 
  is 
  in 
  the 
  horizon 
  of 
  the 
  gypsum. 
  

  

  Mendon 
  ponds. 
  These 
  four 
  ponds 
  are 
  situated 
  in 
  the 
  north- 
  

   western 
  part 
  of 
  Mendon, 
  and 
  are 
  the 
  sources 
  of 
  the 
  main 
  branch 
  

   of 
  Irondequoit 
  creek. 
  The 
  one 
  which 
  was 
  considered 
  best 
  adapted 
  

   as 
  a 
  source 
  for 
  a 
  temporary 
  supply 
  for 
  Rochester 
  is 
  called 
  Deep 
  

   pond, 
  and 
  is 
  about 
  three 
  and 
  one 
  half 
  miles 
  east 
  of 
  the 
  Rush 
  reser- 
  

   voir 
  and 
  seven 
  miles 
  south 
  of 
  the 
  Mount 
  Hope 
  reservoir, 
  both 
  dis- 
  

   tances 
  being 
  measured 
  in 
  direct 
  lines. 
  Its 
  surface 
  is 
  from 
  100 
  feet 
  

   to 
  110 
  feet 
  below 
  the 
  level 
  of 
  the 
  former 
  reservoir, 
  as 
  determined 
  by 
  

   a 
  barometric 
  observation. 
  The 
  outflow 
  is 
  about 
  500,000 
  gallons 
  

   per 
  day. 
  Under 
  these 
  circumstances 
  they 
  could 
  not 
  be 
  regarded 
  

   as 
  available 
  for 
  the 
  needs 
  of 
  the 
  city 
  of 
  Rochester. 
  

  

  Pond 
  near 
  Bushnell 
  Basin. 
  This 
  pond 
  is 
  located 
  in 
  the 
  south- 
  

   western 
  part 
  of 
  Perinton, 
  and 
  is 
  somewhat 
  more 
  than 
  eight 
  miles 
  

   southeast 
  of 
  the 
  Mount 
  Hope 
  reservoir 
  in 
  a 
  direct 
  line, 
  while 
  its 
  

   surface 
  is 
  about 
  208 
  feet 
  below 
  the 
  level 
  of 
  said 
  reservoir. 
  Consid- 
  

   ered 
  by 
  itself, 
  the 
  pond 
  could 
  not 
  be 
  regarded 
  as 
  capable 
  of 
  fur- 
  

   nishing 
  a 
  daily 
  supply 
  of 
  2,000,000 
  gallons 
  for 
  a 
  long 
  period, 
  since 
  

   it 
  has 
  a 
  very 
  small 
  catchment 
  area, 
  no 
  visible 
  outlet, 
  and 
  does
