® Sedimentation Pond 004 <br />The design information and calculations for this pond were submitted in the Seneca II <br />Permit Renewal Application August 27, 1986 and subsequently approved by CMLRD. On <br />September B, 1986, Sedimentation Pond 004 was resurveyed as part of Seneea's 1966 annual <br />sediment survey. The survey information was utilized to develop a computer-generated <br />contour map. This data was used to calculate the remaining sediment storage beneath the <br />principal spillway. <br />The following table shows a comparison of the 1965 and the September E, 1986 volume <br />calculations. <br />1985 September 8, 1986 <br />Capacity Total Capacity Capacity Total Capacity <br />Elevation (AC-Ft) (AC-Ft) Ac-Ft) (Ac-Fi) <br /> 6936.0 <br /> 6937.0 <br /> 6938.0 <br /> 6939.0 <br /> 6940.0 <br /> 6941.0 <br /> 6942.0 <br /> 6943.0 <br /> 6944.0 <br />6945.2 <br />6946.0 <br />0.054 0.05 0.050 0.05 <br />0.199 0.25 0.141 0.?9 <br />0.442 0.69 0.331 0.52 <br />0.729 1.42 0.623 1.15 <br />1.039 2.46 0.883 2.03 <br />1.331 3.79 1.114 3.14 <br />1.615 5.41 1.372 4.51 <br />1.914 7.32 1.658 6. <br />2.634 9.96 2.494 ~ 8.67 <br />2.067 12.02 2.067 10.73 <br />G-5 <br />
