an early season and north of Great Slave Lake we encountered ice condi:ions 
which probably remained the entire summer as the large deep lakes still had 
large pans of ice on July 2%, only a short distance north of Great Slave Lake. 
Along the Arctic coast the ce: ice was practically solid except at the River 
mouths from Aklavik to Perry River during the latter part of July. In the 
deep lakes near Bathurst Inlet, it is doubtful if the ice went out at-all. 
The major rivers were open almost on schedule so it is doubtful if the late 
season adversely affected nesting on the large river deltas. 
No major floods occurred on the major river deltas and water elsewhere 
was normal except for the ice. 
Summary 
During the period June 11 to July 31 the writers traveled avproximately 
11,000 miles on waterfowl survey work in the Canadian Arctic regions, an area 
extending from Old Crow Yukon to Perry River, N. W. T. and south as far as 
Lake Athabaska. The size of the sample on which actual counts were made was 
700 square miles. 
In the areas surveyed, the waterfowl population varied considerably 
between species and areas. Increases were recorded for pintails, mallards, 
shovelers, canvasbacks, green-winged teals, buffleheads and old-squaws. A 
no-change status was indicated for baldpates, scaups, golden-eyes, redheads, 
ruddy ducks, mergansers, gadwalls, black brant, white-fronted geese and swans, 
while a decrease was recorded for scoters, king eiders, Canada geese and 
snow geese.
