no eow Of water when river is low.

mo row or wafer NNth river - lpNs
Tuckahoe pond (miscaIed TuckahOe
creek il an arm or branch OF back
river water extending from the canal
feeder near nIne-mile lock about two
mies, where it Is joined by the small
creek streams flowing from the bed
Of the old canal and the stream OF
TuckahOc creek proper. This pond con-
tainS approximately ll.2l6.il0 gallons OF
water, and has discharged into il from these
creeks 1888. 400 gallons in twenty-four
hours, so that il no change should take
place IN this pond OF back water from the
flow OF river water through the feeder
which produces the pond. the rate OF flow
from these bold-running creek streams
would about renew it each day, and it is
therefore in no sense stagnant pond.
The feeder from the river near B0sher''s
dam brings into the canal 2I1, ,430.400 gal-
Ions Of water in twenty.fOur hours in
rapid and continuous current for nearly
seven miles, at the rate OK about one mile
an hour. Blythe addition OF all the streams
flowing into the canal along its course this
quantity is increased al the new pump
house 10 2SS. $50, 200 gallons in twenty-four
houIs. or the river water has had less than
one part in twenty-five added to it from all
the small streams combined. The largest
creek (Tuckahoe) does not add one part In
seventy to the river water where it comes
through the feeder.
The chemical examinations show that
the water at the fore-bay at the new pump
house, where it enters the pumps, IL even
better than the river water IN the feeder
from BOsher's dam before the creek waters
mix with il, and that there is no practical
difference between this water in the fore
bay at new pump-w0rks and the river water
flowing into the canal at three.mile-lock
feeder. These anslyses show Just what
should have been expected in that great
volume, rapidity OF current, and aeration
throughout the distances travelled have re-
moved. il any ever existed, the cohtaml-
mating influences Of the creeks.
Each year there are times OF low water in
the river when no flow comes into the canal
feeder at three-mile lock, the feeder at nine
mile locks then furnishing the whole sup
ply TO ouI works and the mills in the city.
AT such times the same water FROM the fore
bay. after passing through the wheel~at the
pump-house, would be drawn in again
through suction-pipe placed in the feeder.
| therefore see no reason why the suction
pipe. as now located, should be changed or
extended into this feeder.
II there are any points along the line Oh
our works where the water is in any way
liable to be polluted by the acts Of parties
living there. we have full authority under
our charter to prevent it. As there has
been some complaint OF the drainage into
the canal from the Richmond Granite Com.
pany's Philadelphia) quarry, recommend
that this company be required to carry
their drainage across and under the canal
through pipe or culyert.
Respectfully submitted.
W. T.. CCTSHAw, City Engineer.

On motion OF Mr.. DckersOn the reports
were received and filed.

Mr.. Dickerson moved TO reconsider the
motion IN reference to change OF receiy'
ing the water supply.
The City Engineer and the City Attorne!
