PART 208--FLOOD CONTROL REGULATIONS--Table of Contents
 
Sec. 208.34  Norman Dam and Lake Thunderbird, Little River, Okla.

    The Bureau of Reclamation, or its designated agent, shall operate 
Norman Dam and Lake Thunderbird in the interest of flood control as 
follows:
    (a) Flood control storage in Lake Thunderbird between elevation 1039 
(top of the conservation pool) and elevation 1049.4 (top of flood 
control pool) initially amounts to 76,600 acre-feet. Whenever the 
reservoir level is within this elevation range the flood control 
discharge facilities at Norman Dam 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 reservoir. In order to accomplish this purpose, flood 
control releases shall be limited to amounts which, when combined with 
local inflows below the dam, will not produce flows in excess of 
bankfull on the Little River downstream of the reservoir. Controlling 
bankfull stages and corresponding flows, as presently estimated, are as 
follows: A 7.5-foot stage (1,800 c.f.s.) on the U.S.G.S. gage on Little 
River near Tecumseh, Okla., river mile 77.2 and a 17-foot stage (6,500 
c.f.s.) on the U.S.G.S. gage on Little River near Sasakwa, Okla., river 
mile 24.1.
    (b) When the reservoir level in Lake Thunderbird exceeds elevation 
1049.4 (top of flood control pool), releases shall be made at the 
maximum rate possible through the river outlet works and the 
uncontrolled spillway and continued until the pool recedes to elevation 
1049.4 when releases shall be made to equal inflow or the maximum 
release permissible under paragraph (a) of this section, whichever is 
greater.
    (c) The representative of the Bureau of Reclamation or its 
designated agent in immediate charge of operation of the Norman Dam 
shall 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 Engineer showing the pool elevation; the number 
of river outlet works gates in operation with their respective openings 
and releases; uncontrolled spillway release; municipal pumping rate; 
storage; tail water elevation; reservoir inflow; available evaporation 
data; and precipitation in inches. Normally, 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 1039 and releases for flood 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 once daily thereafter in that manner until the 
reservoir level recedes to elevation 1039. These latter reports shall 
reach the District Engineer by 9 a.m. each day.
    (d) The regulations of this section, insofar as they govern use of 
flood control storage capacity above elevation 1039.0, are subject to 
temporary modification in time of flood by the District Engineer if 
found desirable on the basis of conditions at the time. Such desired 
modifications shall be communicated to the representative of the Bureau 
of Reclamation and its designated agent in immediate charge of 
operations of the Norman Dam by any available means of communication, 
and shall be confirmed in writing under date of the same day to the 
Regional Director in charge of the locality, and his designated agent, 
with a copy to the representative in charge of the Norman Dam.
    (e) Flood control operation shall not restrict pumping necessary for 
municipal and industrial uses and releases necessary for downstream 
users.
    (f) Releases made in accordance with the regulations of this section 
are subject to the condition 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 or inconsistent with 
the safe routing of the inflow design flood (spillway design flood).
    (g) The discharge characteristics of the river outlet works (capable 
of discharging approximately 5,400 c.f.s. with the reservoir level at 
elevation 1039.0) shall be maintained in accordance with the 
construction plans (Bureau of Reclamation Specifications No. DC-5793 as 
revised by the ``as built drawings'').
