<br />The procedure for computing the routed hydrograph is illustrated by <br />continuing the example for Log Lake Dam (fictitious). The dam failure <br />hydrograph was previously calculated and shown in figure 5. The study area <br />below the dam is shown in figures 8 and 9. <br /> <br /> <br />REACH 2 <br /> <br />5 <br />STR <br /> <br />Miles Below Dam <br /> <br />3 <br /> <br />D D <br />Houses <br /> <br />4 <br /> <br /> <br /> <br />:; 20 FT <br /> <br />Scale <br />I Mile <br /> <br />Figure 8.
