Description:	Miscellaneous Paper Abstract: During the period January 1941 through December 1946 evaporation measurements were made at lake and land evaporation stations established at the U.S. Army Engineer Waterways Experiment Station, Vicksburg, Miss. These stations were of the U.S. Weather Bureau Class A type modified during the test period to meet the needs of specific short-term objectives without jeopardizing the long-term program results. The results of the study are summarized in tables and plates presented in this report. The data obtained during the study indicate that evaporation from the land station was 80 percent of that from the floating lake station. This difference is attributed to the fact that the average wind speed at the land station was less than 50 percent of that at the lake station. Normally, the evaporation from a lake station is appreciably less than that from a comparable land station. Careful measurement of the lake surface elevation changes, and dam seepage during periods of negligible lake inflow and light rainfall, indicated that evaporation from the lake water surface averaged 75 per cent of that measured at the floating pan during specifically selected time period. The extreme variations were 56.7 and 92.3 percent.
