Sec.  208.27  Fort Cobb Dam and Reservoir, Pond (Cobb) Creek, Oklahoma.

    The Bureau of Reclamation shall operate the Fort Cobb Dam and 
Reservoir in the interest of flood control as follows:
    (a) Whenever the reservoir level is between elevation 1342.0, top of 
the conservation pool, and elevation 1354.8, top of flood control pool, 
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 reservoir. All flood control 
releases shall be made in amounts which, when combined with local inflow 
below the dam,

will not produce flows in excess of bankfull on Pond (Cobb) Creek 
downstream of the reservoir and on the Washita River downstream of their 
confluence. In order to accomplish this purpose, flows shall not exceed 
a 13.0-foot stage (1,300 cfs) on the USGS gage on Pond (Cobb) Creek near 
Fort Cobb, Oklahoma, river mile 5.0; a 19.0-foot stage (6,000 cfs) on 
the USGS gage on the Washita River near Anadarko, Oklahoma, river mile 
305.0; or a 19.0-foot stage on the USGS gage near Bradley, Oklahoma, 
river mile 210.6.
    (b) When the reservoir level exceeds elevation 1354.8, top of flood 
control pool, releases shall be made at the maximum rate possible and 
continued until the pool elevation recedes to elevation 1354.8 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 in immediate 
charge of operation of the Fort Cobb 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 elevation of the reservoir level; number of river outlet 
works gates in operation with their respective openings and releases; 
uncontrolled spillway and municipal outlet works release; storage; 
tailwater elevation; reservoir inflow; available evaporation data; and 
precipitation in inches. Normally, one reading at 8:00 a.m., shall be 
shown for each day. Readings of all items except evaporation shall be 
shown for at least three observations a day when the reservoir level is 
above elevation 1342.0. Whenever the reservoir level rises to elevation 
1342.0 and releases for flood regulation are necessary or appear 
imminent, the Bureau representative 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 1342.0. These latter reports shall reach the 
District Engineer by 9:00 a.m., each day.
    (d) The regulations of this section insofar as they govern use of 
the flood control storage capacity above elevation 1342.0 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 in immediate charge of operations of the Fort Cobb 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, with a copy to the representative in charge of the Fort Cobb 
Dam.
    (e) Flood control operation shall not restrict releases necessary 
for municipal-industrial and irrigation uses:
    (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 
safe routing of the inflow design flood.
    (g) All elevations stated in this section are at Fort Cobb Dam and 
are referred to the datum in use at that location.
