Brood counts on the key goore arean of northern Utah have been made 
and the following summariges theee data. No satisfactory means has been 
devised to get eimilar information from the Blackfoot Reservoir. However, 
duat prior to the banding steaeon in late dune a ceneus of geese revesled 
approximately 3,000 geese on the area. These were largely adult feene.

Copelusions 
These data show a progressive decline in geese produced at Bear River 
Refuge since 1946. The areas eurrounding the Refuge, Ceden Bay to the south 
and the Fublie Shooting Grounds to the north, have shown increases in 1949 
over 1942. FPurther to the south on Farmington Bay there 1s 4160 an increase 
in googe production. In epite of these increases the cooce production in 
nerthern Utah was reduced approximately 7 percent from that of 1948. 
Conditions at Blackfoot Reservoir must be aupraised by the fete of the 
neste under observation ac & method of obtaining complete brood counts has 
not been fully worked out. A 53 percent hatch was observed. Thies would 
approximate a near normal hatch for this area, but a hatch considermbly 
below the normal for Utah areas. A diecnuseion of the Low hatch at Blackfoot 
Reservolr was given in Special Scientific Eeport 60, U.8.D.1. and Canada 
Department of Mines and Resources.
