<br />I ~OJ"~86 <br /> <br />from this space. <br /> <br />Dead Capacity. - The reservoi r capacity from whi ch stored water cannot be <br />evacuated by gravity. <br /> <br />Reservoir (cant) <br /> <br />Maximum Water Surface. - The highest acceptable water surface elevation with all <br />factors affecting the safety of the structure considered. It is the highest <br />water surface elevation resulting from a computer routing of the inflow design <br />flood through the reservoir under established operating criteria. This surface <br />elevation is also the top of the surcharge capacity. <br /> <br />Maximum Controllable Water Surface. - The highest reservoir water surface <br />elevation at which gravity flows from the reservoir can be completely shut off. <br /> <br />Normal Water Surface. - The elevation at the top of the active conservation <br />capacity. The maximum elevation to which the reservoir may rise under normal <br />operating conditions exclusive of flood control storage. (The term is no longer <br />used by the Service but is offered because of its prior usage). <br /> <br />Top of Exclusive Flood Control Capacity. - The reservoir water surface elevation <br />at the top of the reservoir capacity allocated to exclusive use for regulation <br />of flood inflows to reduce damage downstream. <br /> <br />Top of Joint Use Capacity. - The reservoir water surface elevation at the top of <br />the reservoir capacity allocated to joint use, i.e., flood control and <br />conservation purposes. <br /> <br />Top of Active Conservation Capacity - The reservoir water surface elevation at <br />the top of the capacity allocated to the storage of water for conservation <br />purposes only. <br /> <br />Top of Inactive Capacity. - The reservoir water surface elevation below which the <br />reservoir will not be evacuated under normal conditions. <br /> <br />6 <br />
