"Trends and serial correlations have been examined for series of annual flows and annual precipitations for 17 streamflow and 9 precipitation stations in British Columbia. This was undertaken to determine if there were statistically distinct trends in mean annual values which could bias regional analysis. No province-wide statistically distinct trends were found, although mean flows and precipitations were lower in the 1920's, 1930's, and 1940's than in the 1950's and 1960's. The maximum deviations of 5, 10, 15 year mean flows from 40 and 50 year mean flows were studied also to provide an indication of the extent to which short term means can differ from long term means"--Abstract, page v.
