Mr. Hamarat <br />March 1, 2013 <br />Page 2 <br />precipitation (PMP) event. The available flood storage capacity in the system at the time of <br />the survey significantly exceeds the storage requirement. However, this excess capacity will <br />decrease throughout the coming year as additional inflows to the system occur and a portion <br />of the storage space is filled with deposited tailing. In comparison to previous years, there is <br />significantly more storage capacity in the TSF this year than previous years. This is <br />primarily due to significantly less than average precipitation in 2012 and two consecutive <br />years of good tailing dam building. <br />A relatively accurate determination of the flood storage capacity in the impoundment can be <br />made at the time of the surveys in May and October. An operations model has been <br />developed to estimate the flood storage availability in the system between surveys and is <br />updated by Henderson personnel on a monthly basis. One of the reports generated by this <br />model is the attached TSF Report. This report shows the flood storage conditions in the <br />system on a monthly basis throughout the period from October 2011 to October 2012. The <br />last column of this table verifies that at least 3,582 acre -feet of storage capacity was <br />available throughout the period. The attached graph shows the actual water level in the <br />TSF as compared to the "Hi -Hi" level in the pond, which is defined as the level <br />corresponding to 3,582 acre -feet of available capacity. <br />If you have any questions regarding the enclosed information, or if you require additional <br />information, please call . <br />Sincerely, <br />W.
