<br />44. BARRIER DA~ REPLACEMENT STORAr.E.- The existing BArrier nam
<br />wi 11 be removed from the river to permit construction of rueb 1 0 Dam and
<br />Reservoir. Replacement storage of 21 ,000 acre-feet wi 11 be incl uded
<br />in the new project to offset the loss of flood control storage presently
<br />provided hy Barrier Dam. TIlis is in addition to flood control require-
<br />ments to control the design flood. The storage at Barrier Dam is due
<br />to surcharge since there are no control gates on the existing structure.
<br />The surcharge flood control storage is induced upstream from the eX-
<br />isting dam by forcing f1oodflOl's through a 41. 5-foot notch. The Bureau
<br />of Reclamation plans to replace this storage by surcharge storage above
<br />the spillway crest of Pueblo Reservoir.

<br />ECONOMIC DATA
<br />
<br />45, AREA OF INFLUENCE, - The economic area influenced by construc-
<br />tion of the multiple-purpose Pueblo Reservoir includes that part of the
<br />Arkansas River drainage upstream from John Martin Dam. The area in-
<br />cludes the following counties in Colorado: Bent, Chaffee, CrOl,ley,
<br />Custer, El Paso~ Fremont, IJl1erfano, LakeJ. Las Animas. Lincoln, Otero,
<br />Pueblo, and Teller. These counties are 5h')I;n on plate 7. The popula-
<br />tion and areas of the cowlties arc listed in tahle 4, These counties,
<br />comprising a tct:ll area of 21,:\3:\ squ"re THIes, would be strongly in-
<br />fluenced by development of water resources due to eeonomic ties and
<br />geography, Also in the basin, but excluded from the area economic study
<br />because of negligible areas and sparse population, are parts of Baca,
<br />Costilla, Kiowa, Park, Elbert, and Saguache Counties in Colorado, and
<br />Colfax and Union Counties in New Mexico. Various segments of the econ-
<br />omy have heen evaluated with regard to prescnt influence upon the area
<br />and future potential development,

<br />the history of Colorado and the study area hegan thousands of years ago
<br />with a race of people of which little is knoHn, the modern era could be
