Furthermore, Imperial <br /> <br />Valley return flows, which go to Mexico, have been ignored. <br /> <br />There are seven reservoirs represented in the model network. These are <br /> <br />described in Table 111-6. Generally, these reservoirs represent directly the <br /> <br />active capacity of a real reservoir of the same name. There are two exceptions: <br /> <br />In the model, the conservation pool (as opposed to the flood control pool) of <br /> <br />Lake Mead has been consolidated with the capacity of Lake Havasu and Lake <br /> <br />Mojave. These reservoirs are operated as one. The total capacity of the seven <br /> <br />reservoirs, including the Mead flood pool, is 62,489,000 acre-feet. The <br /> <br />~ <br /> <br />reservoirs were assumed to be full at the start of each simulation. <br /> <br /> Table III-6: Reservoirs <br /> Assumed <br />Name Node Capacity Dead Storage Starting Contents ~ <br />Fontenelle 1 345 195 345 <br />Flaming Gorge 2 3789 40 3789 <br />Curecanti 3 1058 HI 1058 <br />Navaho 4 1709 13 1709 <br />Powell 5 27000 1998 27000 <br />Mead Conservation 6 23088 0 23088 <br />Mead Flood Pool (1) 7 5500 0 5350 <br />Total 62,489 <br /> <br />1 USCOE, USBR, 1982. <br /> <br />The flood pool of Lake Mead has been separated from the conservation pool <br /> <br />to allow realistic modelling of the rules used by the Interior Department to <br /> <br />operate Lake Mead for flood protection.
