The report provides methods for estimating flood characteristics in Wisconsin, using equations based on flood peak records and basin characteristics. Key factors like drainage area, slope, and land features were found to be important in predicting flood frequencies. The equations can estimate floods for different recurrence intervals, like a 25-year flood for smaller areas and a 100-year flood for larger ones. Graphs are included for regulated streams where the formulas may not apply. The findings help in planning and design by providing valuable flood information for various locations in Wisconsin.
