Includes bibliographical references (page 11). "There are thousands of lakes in Canada, many of them still nameless, of which little or nothing is known relative to their water resources potential. To date, progress has been slow in establishing the hydrometeorological characteristics of these lakes due mainly to their sheer numbers and to the relative inaccessibility of much of Canada’s lake country. Recently, however, newly developed infra-red sensing techniques combined with aerial surveys have made possible the fast and convenient measurement of surface water temperatures of such water bodies from the air. The resulting water temperature data have, in turn, led directly to improved estimates of evaporation losses from the same lakes--Introduction. Water temperature Ontario, Northern.
