<br />Plate 1 0 is a sketch prepared by the Bureau
<br />of Reclamation which shows the location of and
<br />facilities in T opock Marsh.
<br />The River Management Program now has a
<br />new phase, as a result of Section 306 of P.L.
<br />90-537 which states:
<br />
<br />The Secretary shall undertake program' for
<br />water salvage and groundwater recovery along
<br />and adjacent 10 the mainstream of Ihe Colorado
<br />River. Such programs shall be consi,tent with
<br />maintenance of a reasonable degree of undisturbed
<br />habitat for fish and wildlife in the area, a' deter-
<br />mined by the Secretary.
<br />
<br />Power
<br />Hoover Plant Operations. Storage at Lake
<br />Mead has been relatively low in recent years
<br />due to the effon to fill the Colorado River Stor-
<br />age Project reservoirs. Releases at the Hoover
<br />Powerplant have been made only in the amounts
<br />required to meet downstream water require-
<br />
<br />ments. At the Power Integration meeting of
<br />Hoover power allottees held on June 29, 1967,
<br />to program operation of the plant for 1967-68,
<br />total release for 1967-68 power operation year
<br />(June I-May 31) was estimated at 8,278,000
<br />acre-feet, and Hoover energy deliveries to the
<br />allottees at 2,993 million kilowatt-hours, which,
<br />together with the estimated replacement energy
<br />for Hoover firm deficiency caused by initial fill-
<br />ing of Upper Basin reservoirs, would result in
<br />a total delivery of approximately 3,661 million
<br />kilowatt-hours or about 90 percent of defined
<br />contract firm energy for the year ending May
<br />31, 1968. The actual Hoover release during the
<br />year was 7,828,000 acre-feet and the total energy
<br />delivered to the Hoover power allottees was
<br />3,617 million kilowatt-hours. Of this total,
<br />Hoover generation was 2,802 million kilo\Vatt-
<br />hours, Hoover to Parker-Davis Interchange
<br />amounted to 7 million kilowatt-hours and re-
<br />placement energy amounted to 822 million kilo-
<br />watt-hours.
<br />Releases from Hoover Dam and delivery of
<br />energy to Hoover power allottees for the past
<br />6 years are shown on Table 7.
<br />At the Power Integration meeting on June
<br />26, 1968, the Bureau of Reclamation estimated
