Route through sub-watershed Q 31, Develop hydrograph for sub-watershed Q 32. Develop hydrograph for sub-watershed R 33, Combine three hydrographs 34. Route through sub-watershed S 35. Develop hydrograph for sub-watershed S 36, Combine two hydrographs Sub-watersheds D, H, J, and S could be modeled using the kinematic wave method because they tend to flow laterally into the stream, However, the net effect of the peak flows of these four sub-watersheds computed by this method on the peak flows from the entire watershed at Holoyoke is not expected to be significant. Therefore, this refinement is not considered necessary, Draft Letter Report Independent Review of Hydrologic Analysis for Frenchman Creek Contract No. DACW41-00-D-0026-000l Flood Plain Management Services Special Study Holyoke, Colorado June 18.2001 Page 8
