Seven grad~ stabilization ar~ ~edim~~t control structures were constr~c,ed.

The U. S. Geological Survey has i~stalled two stream gagine and ged1m~~t
load station~, and five water stage recorders Within reservoirs. (S~e

V. Instrumentation

The stream rloo' records being published at present in the U. S. Gp~:vg1cal
SurWl"; Surface ,;ater Supply Papers, Part 63, Mi85our1 Ri""::- dasin 'ce10w
Sioux Ci~y, Iowa are as /0110'.s:

In$t~~ents and measuring devices were ins~alled to measure precipitation,
stream flow, sediment and flood crests ~~thin the watershed. (See Figure
1 for location). The following is a listing of th~=e installations.
A. Ra.ingages.
4 recording gages
10 standard gages

Kiowa Creek at X~lj Recervoir near Eastonville, Colorado
Kiowa Creek at Elbert, Colorado
Kiowa Creek at Kiowa, Colorado

B. 2 stream gaging and sediment load stations.

c. 5 water stage recorders within reservoirs.
D, 5 stream crest gages with mon~~ented ends. These monuments are
brass caps installed in concre~e.

In Hay and June 1956, t~nty-six chanr.e1 cross sections were su~~yed and
monumented for the purpose nf determining peak nood flows, cha.r.ges in
cha.'1Ilel rcgime and cha:-.nel geometry along the East Fork, West Fork and
main stem nf the Kiowa Creek. At present twenty-four of these sections
are mnnumented to provide for future measurements of changes in channel
regime, The roonUll".ents are brass caps installed in concrete posts.

The installatiOll and operation of instnm:tmts were accomplished by con-
tracts ~th other agencies, The U. S. Weather Bureau collects pr"cipi_
tation data, and the U, S. Genlogical Survey collects stream flow and
suspended sediment measurements, The Soil Cnnservation Service and local
farmers in the area alsn assist in the collection of these data.

Water surface prnfiles wcre c~uted from the channel cross sections of
the Kiowa Creek, Stage discharge and stage cross section area curves
rnr each seotion are availab]e, (See Figures 10 through l8). Plots of
the ch~\llel crnss sections ~e shown in Figures 19 through 29. Cross
section locations are shown on the plan map in Figure 1.

Present plans arc to operate the instrumentation until the completion of
the study period at the end of fiscal yeat" 1966,

The rain ~ages have been assigr:.ed identification 8ymbo1s by the Weather
Bureau. Some gages have bee~ relocated .~thin the study period ~d have
be~n gtv~n npw idpntLfication as noted in T~blc J, The original set of
4 recording gages a.~d 10 standard gages was installed in December 1954.
In Jll..."l\:&rYl956 the Weathel' Bureau began the publication M tr.e precipi-
tation recnrd~.

Five stream crest gage crose sections are installed with monumented ends,
These sections .'ere intended to record tr.c ;:>,1l.xi:..W1I depth or 1'lOod3 when
they occur. See Figure 1 for location and Figures 30.]4 for plots of the
cro~s secUons.
