This report contains rainfall and runoff data collected during the 1975 water year for Sycamore Creek, Sycamore Creek tributary , Dry Branch, and Little Fossil Creek study areas in Fort Worth, Texas. The information will be useful in determining the extent to which progressive urbanization will affect the yield and mode of occurrence of storm runoff. Detailed rainfall-runoff computations, including hydrographs and mass curves, are presented for nine storm periods during the water year. (Woodard-USGS)
