OREGON 
Weather and Water Conditions - ''Weather and water conditions have 
been ideal with a record amount of water available in the main breeding areas", 
Precipitation was heavy and temperatures much: below normal during April, 
May. and June. 
| maton en Bepelation Indices - No totals for the State given... Breeding pairs 
per square mile of sample transects in eastern Oregon showed 53'pairs per 
_ Square’mile in, 1953 and 49 in 1952,.an 8 percent increase, The 1953 figure 
also was l6 percent above the 4-year average, Transects West of the — ' 
Cascades showed a 35 ‘percent decrease compared to 1952, "Wor the entire. 
State,’ the > breeding population remained about the same as in 1952," 
Conclusions ~ It is estimated that Oregon will prodiee about the same sennee 
of birds as last year. 
UTAH 
'. Weather and Water Conditions ~ Mild open winter with early Spring. 
Unseasonable cold weather and snow storms in the early spring were adverse: 
to nesting geese and ducks. The late nesting season was good with little high 
runoff water to flood nesting areas,'"' 
Breeding Population Indices - Surveys were extended this year to give greater 
coverage, Over 72 Square miles sampled comparatively, the ducks per square 
mile in 1953 increased 10.4 percent over 1952, In the State as a whole, the 
surveys resulted in an estimate of 36,444, Per seis of breeding BUEN and },112 
Paes of breeding peesé, -_— 
Conclusions - in view of the small increase in breeding populations and the 
favorable water conditions, it is estimated that the fall flight of ducks from 
Utah will be slightly larger than in 1952, 
CALIFORNIA 
Weather and Water Conditions ~ Water conditions were again nearly ideal . 
with winter precipitation filling all lakes and impoundments, Weather was 
unseasonably mild during late winter which caused birds to move northward 
earlier than usual,- but temperatures were below normal during April, May, 
' and June, This cold weather caused nesting to be about two weeks later than 
normal,
