Snow survey courses and precipitation stations were established in the Great Basin of western Newfoundland as early as 1928. the need for this network of hydrologic stations was to create records to be used in forecasting the probable water supply for a hydroelectric power development used to operate a paper mill at Corner Brook, Newfoundland. Results of the forecast scheme, from 1926 to 1935 were consistently LESS than actual flows. A corrective procedure is presented by using graphical and statistical methods to correct the minus errors with actual forecast volumes and thereby correct the errors to a more dependable figure. Data are exhibited in tables and the graphical solution with statistical methods are shown and discussed.Discussion by Fred Paget points out the need for such procedures to find the causes for consistent minus or plus forecasts being caused from some unmeasured hydrologic factors. Paget also refers to similar procedures discussed in WSC paper No. 44-38, and Elges WSC paper No. 64-39.
