Goose Production 
June 1 of last year was the first season that a survey of goose production 
had been undertaken. At that time the young at Washoe Lake were mostly Class II's 
and some Class I's, while at Lahontan and Pyramid Lakes the groups were Class III. 
This year the goose production survey was begun in April when 52 goose nests 
containing 279 eggs were located at Washoe Lake. Early checks at the other areas 
revealed scattered pairs. By June the Class I's and II's were found at Washoe Lake; 
and only 21 young at Lahontan Reservoir; and two Class II's at Pyramid Lake. It 
now appears that the 1, 923 geese at Pyramid Lake, the 208 at Lahontan Reservoir 
and the 85 at Walker Lake this year were molting non-breeders, with some 
production occurring at Lahontan Reservoir.
