Ll � <br />0 <br />decreases such that significant deposition occurs or until the flow enters a defined <br />channel. The slope length for PECOCO was determined to be 720 feet. <br />Average Slope The average slope is the typical or representative slope (in percent) for <br />overland flow for the watershed. This was determined to be 22.0 percent. <br />C and P Factors The C factor, the cover and management factor, is the ratio of soil loss <br />from an area with specified cover and management to that from an identical area in tilled <br />continuous fallow. <br />The P factor, the support practice factor, is the ratio of soil loss with a support <br />practice like contouring, strip cropping, or terracing to that with straight -row farming <br />up and down the slope. <br />The C factor was determined with the aid of the USDA -ARS revised USLE software program for <br />each cover type with the overall drainage area. The P factor is based on current or <br />future practice. Table 7 -6G-7 shows the results for the C and P factors for the various <br />areas. Table 7-6G -8 is a weighted average. <br />STORAGE CAPACITY <br />The storage capacity of PECOCO was also analyzed using the SEDCAD computer program. <br />A summary of the designed storage capacity is shown below. <br />Elev. <br />Stage <br />Area <br />Capacity <br />Total <br />(ft.) <br />(ft.) <br />(ac.) <br />(ac.-ft.) <br />(ac. -ft.) <br />6750 <br />0.0 <br />.144 <br />0.0 <br />0.0 <br />6755 <br />5.0 <br />.558 <br />1.75 <br />1,75 <br />6760 <br />10.0 <br />.747 <br />3.27 <br />5.02 <br />6765 <br />15.0 <br />1.071 <br />4.54 <br />9.56 <br />6770 <br />20.0 <br />1.462 <br />6.33 <br />15.89 <br />6774.9 <br />24.9 <br />1,980 <br />x.42 <br />24.31 <br />6775 <br />25.0 <br />1.988 <br />0.10 <br />24.51 <br />6777 <br />Z7.0 <br />2.308 <br />4.30 <br />8.rs1 <br />6780 <br />30.0 <br />2.789 <br />7,65 <br />16.46 <br />6781 <br />31.0 <br />2.950 <br />?7 <br />X3.33 <br />7 -6g-1 5 <br />Description <br />Bottom of Pond <br />Principal Spillway <br />Emergency Spillway <br />fop or Embankment <br />NOR 006575 <br />i <br />
