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.
