STREAMFLOW DURING JULY 1971
Streamflow decreased seasonally in most of the Provinces and States. Principal
exceptions were above-normal precipitation and runoff in several parts of the
Southeast and increased streamflows in Arizona. Principal regional streamflow
characteristics resembled those of June; Flows in the above-normal range in a
multi-State area centered in Idaho and flows in the below-normal range in the
Northeast and in a large area centered in Texas. End-of-month rains in the
Northeast improved the water-supply situation in parts ofthat region.
Very low flows persisted in parts of Oklahoma, New Mexico, and Texas,
although July rains did reduce the extent of the critical areas. Water-supply
conditions improved also in southern Florida, although streamflows continued
to be in the below-normal range.
