The volume of water in the upper
catchment basins OF the Salt, ella,
Verde and San Pedro rivers is slight
ly greater. The depths contained with
in the lower Salt, the lower ella, the
Hassayampa- Aqua Fria and Bill Will
liams Fork river beds are slightly less
than that OF the preceding week.
" lille the Flow Of water within the
last-named rivers is confined to small
and narrow channels, varying in depth
from O.5 foot to 3.5 IT. there is just
barely water enough to divert the
flows from the intakes into the main
canals. The general supply Of water
for irrigating purposes is of sufficient
volume to last for MANI weeks to
come. The Colorado river at Yuma is
receding SLOWLY. and vet remains at an
abnormally high stage.
