A review of Lake Tahoe water levels from 1878 to date is presented with text discussion towards attempting to find some cyclic effect or means of answering the question: 'How often will Lake Tahoe levels fall below the outlet in the next 50 years?' The use of snow survey data and precipitation data are combined in a 'Percentage System' to compute a forecasting formula. Remarkable results were achieved and forecast accuracy is indicated in the text discussion. In discussion by Major E.H. Bowie, the snow-water ratio of newly fallen snow in the Sierra is explained. Mr. A.V. Tallman discussed the effect of precipitation during the run-off season on the Humboldt River as an aid to forecasting. Dr. J.E. Church described a new Snow Survey network of courses and a system for the Colorado River to aid in planning the operation of Boulder Reservoir created by Hoover Dam.
