e. Remarks: This important area showed a five percent 
decrease in breeding Canada geese anda 
22 percent decrease in the fall population . 
Breeding ducks declined 19 percent while the 
fall population decreased 25 percent. Coots 
showed a 29 percent decrease both in the 
breeding and fall populations. Dry conditions 
contributed considerably to the general de- 
crease, especially at Grasshopper Valley, 
Horse Lake, Honey Lake, and Surprise Valley. 
Cold weather and snow storms during April 
also contributed heavily to the low production 
of Canada geese.
