<br />need for regulation of run-ofr to meet the consur.lptive nS<3ds of the area.
<br />
<br />.
<br />
<br />4. In the period of record there have been 28 floods which have
<br />exceeded flood stage s.t Independonce. Kans.. anywhere from .3 foot to
<br />16.1 feet. The area overflor.ed below the proposed reservoirs in 1927
<br />W9.a 12,000 8.cretJ. The maximum area overrloT'ed was 86,000 a.cres. The
<br />average annual flood losses in the past 11 years are '340,000, of which
<br />89 per cent is crop loss. The 8.veraca annual crop value Is ~1,380.000,
<br />or about .20 per aore of la.nd in the flood plain.
<br />
<br />5. The flood plain la.nd below the proposed reservoirs is appraised
<br />at y6,OOO,OOO, urban property at ;3.600,000, and tranaportation and oom-
<br />munioation facilities at -3,100,000, or a grand total of approximately
<br />,...12,800,000.
<br />
<br />.
<br />
<br />6. The proposed flood oontrol project provides for 4 reservoirs
<br />with a total capaoity of 163,000 acre-feet, of which 690,000 ure e.ssigned
<br />to flood control purposes. Total cost is est~ted as 130,120,000. These
<br />reservoirs are ,'the Toronto Reservoir in the upper reaohes of the main
<br />stem, the Neodesha Reservoir just above the lmuth of Fall River, the
<br />Fall River Reservoir on the Fall River, and the Elk Reservoir on Elk
<br />River just about at its mouth. The 4 reservoirs are all located upstream
<br />:from the important oities of Independence and Coffeyville, Kans. These
<br />reservoirs would not provide complete control of the 1904 flood. The
<br />volume of run-off for this flood "taS about h.'"ice that of the seoond.
<br />greatest flood of reoord, and the cost of providing proteotion acainst
<br />a flood of this magnitude is prohibitive. The proposed reservoirs, how-
<br />ever, would have Il\B.terially deoreased the pea.k of the 19)4 flood and
<br />would have provided complete control of all other known floods.
<br />

<br />
<br />7. It is estimated that 15 per cent of the benefits .rould accrue in
<br />the Verdigris valley above 'the Oologah Reservoir and 5 per oent belo't'7.
<br />The remain1n~ 20 por oent of the benefits '!';Quld acorue to the ..rkansas
<br />River and soma credit is taken for a sliGht reduction in ~issiBsippi
<br />River peak flows. It is considered that the preventable direot flood
<br />losses above the Oolo~ah Reservoir W'Quld be ;J~7 ,000, and the indireot
<br />benefits and enhancement in land values ~4Bl,OOO. The oonservation
<br />storage valued at ;35 per aore-foot is valued at approximately ;138,000,
<br />making a total average annual value above the Oologah Reservoir of
<br />;1,046,000. VerdiGris River benefits below the Oolo~ah ~eservolr are
<br />estimated at .;70,000, or a total of ;1,116,000. ,u-kansas and J.riss15-
<br />sippi Rivar benefits are e5ti~ted as ~284,ooo. making a grand total of
<br />01,410,000. The estimated annual oarrying cha.rges are about ;1,270,000.
<br />

<br />
<br />8. The 1936 Flood Control ~ct autnori%ed 3 levee projects and 1
<br />ohannel-olearint projJot in the Verdigris River in Kansas. These proj-
<br />eots v~re for tho protection of the area west of Fredonia, ~st of
<br />Benediot, west of Elk City. Gnd ohanne1 olearing from tr~ mouth of
<br />Madison. Kans. Present indioationa are 'that the requirements of looal
<br />oooperation from these projeots TIill not be met. Local interests are
<br />now definitely opposed to 8.dd1tioM1 projects of these types.
