Abstract: Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq mi. Basin parameters of main channel length, L; and distance along the main channel L//c//a, to a point opposite the centroid of the basin were determined. Values of F. F. Snyder's coefficients C//t and C//p were calculated from standard formulas. For basin #1, Snyder's C//t values ranged from 0. 710 to 1. 228 with a mean value of 0. 894. Values of C//p ranged from 0. 559 to 1. 128 with a mean of 0. 843. For basin #5, Snyder's C//t values ranged from 0. 276 to 2. 173 with a mean of 9 values equal to 1. 18. Values of C//p ranged from 0. 174 to 1. 900 with a mean value of 0. 815. Published values for C//t range from 1. 8 to 2. 2 with no mean value specified. Published values for C//p range from 0. 4 to 0. 8. For both basins, values of C//t tend to be lower and values of C//p tend to be higher than published values.
