“…The thermistors were contained in a shelter consisting of a radiation shield and tetraskelion-design airpassage systems to allow natural wind (as opposed to forced draft) to ventilate the thermistors. The design of these psychrometers is more fully explained by Bellaire and Anderson (1951). Those authors found that accurate water-vapor pressures could be obtained if the windspeed was at least 0.44 m/s.…”

“…The amplifier was of a negative-feedback-galvanometer type with a power consumption of 4 watts. A complete description of the amplifier and the thermocouple psychrometer may be obtained by referring to Anderson, Anderson, and Marciano (1950), Bellaire and Anderson (1951), and Denton (1951). The amplified thermocouple voltages were recorded on a 1 ma Esterline-Angus recorder with a spring-wound-clock chart drive.…”

This report is the third and final one of the series on water-loss investigations conducted jointly by several Federal agencies during the years 1950-53. Previous reports are water-loss investigations: Lake Hefner studies, technical report (Geological Survey Professional Paper 269 and also Navy Electronics Laboratory Report 327, San Diego 52, Calif.) and water-loss investigations: Lake Hefner studies, base data report

General Hydrology Branch, and under the technical guidance of W. B. Langbein. Most of the fieldwork and data processing was performed by personnel of the Surface Water Branch, J. V. B. Wells, Chief, under the supervision of Trigg Twitchell, District Engineer. The study was conducted in cooperation with the Board of Water Engineers, State of Texas, H. A. Beckwith, Chairman, succeeded by R. M. Dixon. The cooperation of the Texas Electric Service Co., Fort Worth, Tex., who assisted with the installation of equipment and whose personnel made many of the routine daily observations, is greatly appreciated. The help of the U. S. Weather Bureau in installing a pan evaporation station at the reservoir is gratefully acknowledged. These data have been furnished to the Weather Bureau for analysis and the results are to be published in a separate report. in CONTENTS I x3tract____________________________________ E troduction_ _______________________________ Ascription of the reservoir and dam___________ }] :matology _ _ _______________________________ c 3trumentation_ ____________________________ Water budget___________________________ Inflow._____________________________ Outflow. ___________________________ Change in reservoir content.__________ Withdrawals for municipal use_ _______ Rainfall on the lake surface ___________ Energy budget __________________________ Radiation measurements.____________ Temperature profiles of the lake..______ Mass transfer.__________________________ Performance and maintenance of equipment.
