Basinwide Conditions Assessment
The SWSI value of -3.3 indicates that for June the
basin water supplies were below normal. Flow at the gaging
station Vampa River at Steamboat was 929 cfs, as
compared to the long~term average of 1,822 cfs.
June was a continuation of the weather pattern seen
this spring: hot and dry. Pre.cipitation across the basin in
June was only about 33% of average, while temperatures
were above normal for the afternoon. highS. C,onditions are
extremely. dry throughout the' basin wi~h soil moisture
contents well below normal.. Stream flows have ranged from
30% to 45% of normal for the entire month.

Outlook
The forecast for July calls for normal precipitation
and temperatures. The monsoon flow from the Gulf of
Mexico has started to enter the state, but so far has only
brought scattered thunderstorms to the area.

Administrative/Management Concerns
. Stream flows are extremely low for this time of year.
Many streams are under administration with little water
available except for the most senior water rights. 'On the
larger rivers many ditches are unable to divert because of
the low flows. Conditions may ease as ranchers begin to
harvest their hay crops, allowing some creeks to go off of
administration.

Public Use Impacts
River flows are nearing record lows for this time
year. Releases from irrigation reservoirs have been greater
than normal. Several fires have occurred in the area, mostly
started by lightening strikes.
