INTRODUCTION

The Arkansas River Compact Administration is extremely interested

in the administration of the Arkansas River between Pueblo Reservoir

and John Harti.n Reser;YQ:Lr: d1..\ring floodl>, pa.rt:Lclllarly those floods

originating above Pueblo Reservoir. The need to detain flood water;s in

Pueblo Rel>ervoir may affect the rights to llse water, including that which

,1'-

can be stored according to CQmPact rulel> in John Martin Reservoir. The.

'-'

administration of flQod wat~rs OCCllrS in a Yer~ limited time frame, and

a greater knowledge of the behavior of the Arkansas River during floodl>

would greatly improve the reliability of the many administrative decil>ionl>

which must be quickly made.

PROPOSED FLOOD ROUTING STUDY

This proposal describes the procedures that would be followed by the

U.S. Geological Survey in studying past flooding and predicting the impact

of future flooding of the Arkansas River fro~ above Puebi~ Rel>ervoir

(Arkansal> River at Portland gage) to John Martin Reservoir -(Arkansas River

at John Martin Reservoir gage). The study would begin in the 1977 fiscal

year and conclude on September 30, 1978. Historical peak discharge

records would be used to calibrate an existing reservoir release routing

model and to. develop hyvothe.tical J;loodingcond;l;tions to provide procedural

guidelines for administration of the Arkansas River during flood events.

The study would concentrate on flooqs originating above Pueblo Reservoir

and include tributary flood inflow below Pueblo, A comprehensive final
