﻿HYDROLOGY 
  OF 
  NEW 
  YORK

  stream 
  is 
  included 
  in 
  this 
  measurement. 
  The 
  flow 
  for 
  the 
  month 
  

   of 
  August, 
  1899, 
  was 
  at 
  the 
  mean 
  rate 
  of 
  524 
  cubic 
  feet 
  per 
  second. 
  

   In 
  September, 
  1900, 
  the 
  mean 
  flow 
  for 
  the 
  entire 
  month 
  was 
  609 
  

   cubic 
  feet 
  per 
  second. 
  

  

  The 
  mean 
  flow 
  at 
  Little 
  Falls 
  for 
  the 
  month 
  of 
  August, 
  1899, 
  

   was 
  223 
  cubic 
  feet 
  per 
  second, 
  but 
  this 
  does 
  not 
  include 
  diversion 
  

   to 
  the 
  Erie 
  canal, 
  which 
  may 
  amount 
  to 
  about 
  150 
  cubic 
  feet 
  per 
  

   second, 
  or 
  to 
  a 
  total 
  flow 
  of 
  about 
  375 
  cubic 
  feet 
  per 
  second 
  

   (catchment, 
  1306 
  square 
  miles), 
  which 
  is 
  at 
  the 
  rate 
  of 
  about 
  0.28 
  

   cubic 
  foot 
  per 
  second 
  per 
  square 
  mile. 
  In 
  comparison 
  with 
  the 
  

   flow 
  for 
  the 
  month 
  of 
  August, 
  1899, 
  at 
  Rexford 
  Flats, 
  these 
  figures 
  

   show 
  that 
  the 
  upper 
  Mohawk 
  river 
  is 
  relatively 
  a 
  better 
  water 
  

   yielder 
  than 
  the 
  lower 
  — 
  the 
  low 
  flows 
  from 
  Schoharie 
  creek 
  and 
  

   contiguous 
  catchment 
  areas, 
  probably 
  making 
  the 
  difference. 
  The 
  

   lowest 
  water 
  observed 
  since 
  gagings 
  have 
  been 
  kept 
  at 
  Little 
  Falls 
  

   was 
  in 
  August, 
  1899, 
  when 
  the 
  mean 
  flow 
  for 
  nine 
  days 
  was 
  but 
  

   120 
  cubic 
  feet 
  per 
  second, 
  or 
  0.07 
  cubic 
  foot 
  per 
  second 
  per 
  square 
  

   mile. 
  This, 
  however, 
  does 
  not 
  represent 
  the 
  total 
  flow 
  of 
  the 
  

   stream, 
  as 
  nearly 
  the 
  entire 
  river 
  was 
  being 
  taken 
  for 
  the 
  supply 
  

   of 
  Erie 
  canal. 
  

  

  In 
  September, 
  1901, 
  the 
  minimum 
  flow 
  of 
  Mohawk 
  river 
  at 
  

   Utica 
  for 
  two 
  days 
  was 
  70 
  cubic 
  feet 
  per 
  second 
  (catchment, 
  500" 
  

   square 
  miles), 
  or 
  at 
  the 
  rate 
  of 
  0.14 
  cubic 
  foot 
  per 
  second 
  per 
  

   square 
  mile. 
  These 
  figures 
  are 
  somewhat 
  indefinite. 
  

  

  The 
  minimum 
  flow 
  of 
  Mohawk 
  river 
  at 
  Ridge 
  Mills 
  for 
  Septem- 
  

   ber, 
  1899, 
  was 
  at 
  the 
  mean 
  rate 
  of 
  81 
  cubic 
  feet 
  per 
  second 
  for 
  

   twenty 
  -two 
  days 
  ; 
  for 
  three 
  days, 
  the 
  mean 
  flow 
  was 
  56 
  cubic 
  feet 
  

   per 
  second, 
  and 
  for 
  two 
  days, 
  53 
  cubic 
  feet 
  per 
  second 
  ( 
  catchment, 
  

   153 
  square 
  miles), 
  or 
  at 
  the 
  rate 
  of 
  0.34 
  cubic 
  foot 
  per 
  second 
  

   per

  mile. 
  

  

  Minimum 
  floiv 
  of 
  Cayadutta 
  creek. 
  In 
  August, 
  1899, 
  the 
  mean 
  

   flow 
  of 
  this 
  stream 
  at 
  Johnstown 
  for 
  the 
  entire 
  month 
  was 
  18 
  

   cubic 
  feet 
  per 
  second 
  ; 
  in 
  September, 
  20 
  cubic 
  feet 
  per 
  second, 
  and 
  

   in 
  October, 
  21 
  cubic 
  feet 
  per 
  second. 
  For 
  several 
  days 
  during 
  

   these 
  months 
  it 
  was 
  from 
  14 
  to 
  16 
  cubic 
  feet 
  per 
  second. 
  In 
  July 
  r 
  

   1900, 
  the 
  mean 
  flow 
  was 
  17 
  cubic 
  feet 
  per 
  second, 
  and 
  for 
  several 
  

   days 
  it 
  was 
  from 
  12 
  to 
  14 
  cubic 
  feet 
  per 
  second, 
  which, 
  for 
  a 
  catch- 
  

   ment 
  area 
  of 
  40 
  square 
  miles, 
  is 
  at 
  the 
  rate 
  of 
  about 
  0.3 
  to 
  0.35 
  

   cubic 
  foot
