At the Macbride Lakeside Laboratory, Milford, Iowa, the writer began a series of observations last summer (1915) for his own information to ascertain what the fluctuations were in the level of the lake, and to determine the relative value of the causes that operated to produce those fluctuations. It soon became evident that the records sought were desired also by teachers in other departments because of the bearing of such data on life zones and conditions in the lake. Since then the government has called for all data available on evaporation in Iowa. The data are therefore here presented that they may be of immediate use and on file for future reference.
