A community flash flood reporting n~twork of river
and rainfell stations and a flood warning program developed and
operated in connection with the 24_hour Weather Bureau facilities
could minimize 10s3 of life and movable property in the event of
a major flOOd. Such an arrangement would require that local river
and rainfall reports be communicated promptly by responsible local
officials to the Weather Bureau forecast Offioe for evaluation and
analysis. If availsble, this data and analysis would be used by
the Weather Bureau to mOre accurately forewarn community repre-
eentativea of potential storm and flood conditions. This type of
network is preeently in effect in portions of ths Arkansas River
basin and, to an extremely limited degroe, in othor tributary areas.
