Water Planning for Israel is conducting field tests to determine the feasibility of applying long‐chain alcohols on the Sea of Galilee for evaporation reduction. Good film covers have been obtained on 280‐acre Lake Zohar with winds up to 15 mph, and a spray system is being installed on Lake Kishon to test a larger lake with stronger prevailing winds. Using meteorological data and estimated evaporation rates for the Sea of Galilee, the reduced evaporation when covered with an alcohol film has been calculated from the added film resistance. The iterative solution of an energy balance equating the reduced evaporation energy to increased energy storage, back radiation, and conduction to the atmosphere gave a 40% reduction of the annual evaporation rate of 300 million cubic meters when applying a film for a 10‐month period. The film produces a maximum temperature increase of 5°C at the surface.
