<br />Water Year 1996 <br /> <br />Both Lakes Mohave and Havasu are scheduled to be drawn <br />down in the fall and winter months to provide storage space <br />for local storm runoff and will be filled in the spring to meet <br />higher summer water needs. This drawdown will also <br />correspond with maintenance at both Davis and Parker <br />Powerplants which is scheduled for October 1995, through <br />March 1996. The normal fiUing pattern of these two <br />reservoirs coincides well with the fishery spawning period. <br />Since lake elevations will be similar to previous years, <br />relatively normal conditions are expected for boating and <br />other recreational uses. <br /> <br />Accomplishments or the Native Fish Work Group <br /> <br />The Bureau of Reclamation is the lead agency in the Native <br />Fish Work Group (NFWG), a multi-agency team working to <br />replace the existing, aging adult razorback sucker population <br />in Lake Mohave. These fISh average over 4Q years of age <br />and recruitment of young appears to annually fail due to <br />predation by exotic fIShes and other exotic aquatic animals. <br />Projections in 1988 indicated the adult population would die <br />off prior to the turn of the century. <br /> <br />During late winter and early spring of 1995, over 20,000 wild <br />razorback sucker larvae were captured from spawning <br />grounds and reared in lake-side backwater ponds. In the fall <br />roughly 2000 of these fISh were released into Lake Mohave. <br />This brings the total number of young razorback suckers <br />reared in lake-side ponds and released to the lake to over <br />5tXXJ. <br /> <br />The NFWG plans to continue the use of lake-side ponds that <br />fIU with water during late winter and early spring as the <br />reservoir fIUs, and dry up in the faU as the reservoir water <br />levels decline. There is sufficient water during the growing <br />season for these fIsh, and the fall drawdown facilitates fIsh <br />removal. Additionally, the dryout of these areas in late fall <br />removes any non-native fIShes which have gained access. <br /> <br />ACTUAL STORAGE 1995 <br /> <br />MILUON CUBIC MnDtI <br />1.00 <br /> <br />ntOU.....D ACM."HT <br />.... <br /> <br /> ./ ..... <br /> / <br />V <br /> <br />.-- 1100 <br /> <br />1101 <br /> <br />"- <br /> <br />'''' <br /> <br />1100 <br /> <br />1782 <br /> <br />1000 <br /> <br />1820 <br /> <br />1100 <br /> <br />,... <br /> <br />1100 12M <br />~ .I' 4-c, )0/' ~ .r ~.. ,l ~+ ~.. , , <br /> <br />18 <br /> <br />MOST PROBABLE RELEASES 1996 <br /> <br />MlLUOM ~c lllTU18 <br />"" <br /> <br />THOUlANEJ ACIIUI!~T <br /> <br /> I <br /> ,. <br /> " <br /> / "- 17 <br /> J r- r---.. <br /> ., <br /> V "- <br />,/ <br /> .. <br /> .. <br /> <br />,... <br />14" <br />,... <br />,... <br />.00 <br /> <br />... <br />16 <br />.. <br />. <br />. <br />. <br />. <br />. <br /> <br />.oo <br /> <br />... <br /> <br />200 '112 <br />~ 1i'04 .# .; , .r <1" ..;. ~+ ~ ~~ ~ <br /> <br />MOST PROBABLE REGULATED INFLOW 1996 <br /> <br />MIWON CUM: IIETlM <br />,lOG <br />'lOG <br />,... <br /> <br />THOUI.UID ACRIl-PUT <br />,... <br />'16 <br /> <br />".. <br />17. <br />.,. <br /> <br />... <br /> <br /> , <br /> / \ <br /> / ........ <br /> / <br />/ \ <br /> <br />"00 <br /> <br />'''' <br /> <br />lOG <br />... <br />... <br /> <br />... <br />... <br /> <br />zoo 112 <br />R 1'04 #, "'~I'i' ~ ~....;p, <br /> <br />MOST PROBABLE STORAGE 1996 <br /> <br />'"U1OM an!nc IInum <br />110. <br /> <br />TMOUIAND ACIU!!.....n <br />1211 <br /> <br /> I <br /> I <br /> I <br /> ...... r..... <br /> / ........
