Production Data - 
No reliable brood surveys have been made but it is the impression of 
field personnel that a normal hatch occurred and that average brood size will 
be large enough to insure normal production. 
Conclusions - 
It is estimated that Wyoming will produce about the same number of 
sucks as in 1955 but the fall flight of geese will be reduced. 
SOUTH DAKOTA 
Weather and Water Conditions - 
- Drought conditions of 1955 were somewhat relieved this spring by snow 
and run-off.and rainfall. The West-River area and the north-central and 
north-eastern counties of the East-~River area showed substantial improvement 
in water conditions. The remainder of the State, at least, maintained spring 
water conditions of 1955 and evidenced no further deterioration as of the mid- 
May survey. 
The annual mid-May survey showed an average, State-wide density 
of 2.88 water areas (all types) per square mile, This represents a 22 percent 
increase over the 1955 mid-May density of 2.35 water areas per square mile, 
and 33 percent below the 1950 - 1955, six-year average of 4.30 water areas 
per square mile.
