INTRODUCTION

1. Authorization. Preparation of the following report on sedi-
mentation in John ~lartin Reservoir on the Arkansas River in Colorado
was authorized by the District Engineer, Albuquerque District, Corps
of Engineers, Albuquerque, New ~lexico, in accordance with HI 1110-2-
4000, dated 15 November 1961,

2, Genera~. This is the fourth report presenting the results of
sediment investigations in John ~lart:in Reservoir and for the Arkansas
River subbasin above Great Bend, Kansas. It was prepared following
the resurvey of the sedimentation ranges in John Martin Reservoir and
the degradation ranges on the Arkansas River below the dam during Sep-
tember and October 1966. This is the eighth resurvey of the reservoir
ranges and the sixth resurvey of the river ranges since the original
surveys. The last five resurveys have been made on an average of about
once every 4-1/2 years, The first, second, and third reports on sedi-
mentation in John Martin Reserv01r, dated September 1953, June 1960,
and June 1965, respectively, are complete inasmuch as they contain all
pertinent factual data and results of studies conducted prior to those
dates. This fourth report includes the data and results of the investi-
gations obtained since the 1962 resurvey (third report) and a repetition
of previous data and results only where necessary. The trends and con-
clusions are based on all investigations to date. About 300 copies
of the second and third reports were distributed and a limited number
of these are still available for distribution upon request.

3. The sediment investigations program of the Albuquerque District
for the Arkansas River in Colorado consists of collection of suspended
sediment samples at two inflow stations and one outflow station for
John Martin Reserv.oi r, resurveys of sediment rllnges in the reservoir
area, resurveys of ranges below the reservoir for channel changes due
to reservoir operati.on, resurveys of special ranges on the Purgatoire
River to deteI~ine aggradation or degradation at the Atchison, Topeka
and Santa Fe Railway bridge at the Purgatoire River, near the head of
John Martin Reservoir, and associated studies which become necessary
in connection with the sediment program.

4. Purpose. The purpose of this report is to present the data,
analyses, and results of the sediment investigations program since
March 1962 on the Arkansas River located within the Albuquerque District.
Results presented in the report will be used in reservoir operation and
management. They will also be used during studies for flood control,
channel improvement, water salvage, major drainage, and related studies
