One of the most persistent problems
that many irrigators face is that of
trash in their irrigation water. This
problem is almost universal where
water is distributed in open canal and
ditch systems. Trash and debris in the
water not only obstruct irrigation
ditches and structures, but clog sprinkler
nozzles, siphon tubes, gated pipe
openings, and other discharge outlets
and flow measuring devices.

A considerable amount of debris,
particularly during high spring flows,
originates in the streams from which
irrigation water is diverted. Most of
the troublesome material, however, is
generated within the open irrigation
distribution system itself. This
includes moss, snails, garbage, windblown
debris, vegetative material and
soil particles from the irrigation channels
and trash contained in irrigation
runoff or tailwater which is returned
to the canal system.
