Fissl, in constructing d:sches, ths
fall, whether greet OF sosll, sAosld
be as sesrly - possible the ssas
throughout the leagth Of the ditch
Any diminution Of the fall will
cause sediment TO settle and fill the
ditch at that point. The greater
the fall of the ditch, especially at
the headgate, the greater will be the
amount OF sediment drawn from the,
stream. 1t Is customary to construct
dam in stream at ditch's head
gate at right angle to the current 10
secure ditch's full capacity at low
water A shear dam apexed TO
dltch's headgate, if ditch's tall is
small, will throw more Of the finer
silt into ditch. While if fall 10 great
IT will cause too much coarse sand TO
enter.
Distractions, such as rock dams
or boards, driven in the bottom of a
ditch TO raise the water level 10
spread over meadow are wrong IN
principal, as they always cause sedi-
Inent to settle above distractions
The rock, sods or boards should be
placed at sides Of ditch to narrow
but not obstruct center or bottom OF
channel. In irrigating knolls or
high places, the laterals should not
end at the highest point, bat should
he extended through and beyond
the knoll, thus allowing sand and
the heavier PARTICLES Of sediment TO
be carried past the higher point.
Small vents should be cut to con-
duct water over high places II the
ditch ends at highest point, the cur
rent ceases there and sediment is de-
posted where not needed. making
tHe knoll higher and more difficult
of irrigation.
Where there is an abundance Of
sediment in a stream IL can be made
TO play an important part IN leveling
rough places on meadows if proper

bitches or lsterals TO spread the
water when land rs rough and un-
