PART 208_FLOOD CONTROL REGULATIONS--Table of Contents
 
Sec.  208.26  Altus Dam and Reservoir, North Fork Red River, Okla.

    The Bureau of Reclamation, or its designated agent, shall operate 
the Altus Dam and Reservoir in the interest of flood control as follows:
    (a) Flood control storage in the reservoir between elevation 1559 
(top of conservation pool) and elevation 1562 (top of flood control 
pool) amounts to 21,448 acre-feet (based on 1953 sedimentation survey). 
Whenever the reservoir level is within this elevation range, the flood 
control discharge facilities shall be operated under the direction of 
the District Engineer, Corps of Engineers, Department of the Army, in 
charge of the locality, so as to reduce as much as practicable the flood 
damage below the dam, and to limit the reservoir level to elevation 1562 
when possible.
    (b) When the reservoir level is below elevation 1559 and the 
predicted volume of runoff from the area above the dam exceeds the 
volume of water necessary to raise the reservoir level above elevation 
1559, the reservoir will be operated to obtain maximum overall benefits 
which may consist of preflood releases: Provided, That all preflood 
releases will have prior concurrence of the Bureau of Reclamation or its 
designated agent. The preflood releases shall not result in a reservoir 
level below elevation 1559 at the end of the flood.
    (c) When the reservoir level exceeds elevation 1559, releases will 
be made equal to inflow or 2,000 c.f.s., whichever is smaller, except 
that when the reservoir elevation forecast indicates that this operation 
will result in a reservoir level exceeding elevation 1562, releases will 
be increased in order to provide maximum overall benefits and prevent 
the reservoir level from exceeding elevation 1562, insofar as possible. 
The flood control pool will be emptied by continuing the peak discharge 
rate

until the reservoir level recedes to elevation 1559, at which time 
releases will be made equal to inflow.
    (d) If the reservoir level exceeds elevation 1562 (top of flood 
control pool) releases shall be made at the maximum rate possible 
through the spillway gates, conduit, and the uncontrolled spillway and 
continued until the reservoir level recedes to elevation 1559, at which 
time releases will be made equal to inflow.
    (e) Whenever the reservoir level is above elevation 1559 and 
communication with the Bureau of Reclamation Regional Office and the 
Corps of Engineers District Office is unobtainable, releases shall be 
made equal to inflow until all gates are fully open. The maximum release 
thus obtained shall be maintained until the pool recedes to elevation 
1559 at which time releases shall be made to equal inflow.
    (f) The representative of the Bureau of Reclamation, or its 
designated agent, in immediate charge of the operation of Altus Dam will 
furnish daily to the District Engineer, Corps of Engineers, Department 
of the Army, in charge of the locality, a report on forms provided by 
the District for this purpose, showing the reservoir pool elevation; the 
number of spillway gates in operation with their respective opening and 
releases; the uncontrolled spillway release; conduit, canal outlet 
wasteway, and irrigation releases; storage; reservoir inflow; available 
evaporation data; and precipitation in inches. A reading at 8 a.m., 
noon, 4 p.m., and midnight, shall be shown for each day. Whenever the 
reservoir level rises to elevation 1559 and releases for flood control 
regulation are necessary or appear imminent, the representative of the 
Bureau of Reclamation or its designated agent, shall report at once to 
the District Engineer by telephone or telegraph and, unless otherwise 
instructed, shall report at 8 a.m., noon, and 3 p.m. thereafter, in that 
manner, until the reservoir level recedes to elevation 1559. These 
latter reports shall reach the District Engineer by 9 a.m., 1 p.m., and 
4 p.m. each day.
    (g) The regulations of this section, insofar as they govern use of 
the flood control storage capacity above elevation 1559 are subject to 
temporary modification by the District Engineer in time of flood, if 
found desirable on the basis of conditions at the time. Such desired 
modifications shall be coordinated with and approved by the Bureau of 
Reclamation.
    (h) Flood control operation shall not restrict releases necessary 
for irrigation, municipal, and industrial uses.
    (i) Releases made in accordance with the regulations of this section 
are subject to the conditions that releases shall not be made at rates 
or in a manner that would be inconsistent with emergency requirements 
for protecting the dam and reservoir from major damage.
    (j) Any time that the Bureau of Reclamation determines that 
operation in accordance with the regulations of this section will 
jeopardize the safety of Altus Dam, they will so advise the District 
Engineer and will assume operational responsibility and take action 
necessary to assure the safety of the dam.
    (k) The discharge characteristics of the controlled and the 
uncontrolled spillways (capable of discharging approximately 42,800 
c.f.s. and 2,000 c.f.s., respectively, with the reservoir level at 
elevation 1562) shall be maintained in accordance with the construction 
plans (Bureau of Reclamation Drawing No. 258-D-69).
    (l) All elevations stated in this section are at Altus Dam and are 
referred to the datum in use at that location.
