<br />DESCR!PTION OF STUDY AREA
<br />
<br />The study area is located in Central Colorado in the vicinity of Buena
<br />Vista, Chaffee County. Approximately 6 miles of Cottonwood Creek main
<br />channel and 3.3 miles of overflow secondary channels make up the study
<br />area, see location map. The contributing drainage area includes the
<br />South, middle and North Forks of Cottonwood Creek, approximately 100
<br />square miles. The drainage originates at the Continental Divide and is
<br />tributory to the Arkansas River near Buena Vista.
<br />
<br />SCOPE
<br />
<br />Cottonwood Creek flows in an Easterly direction through the town of
<br />Buena Vista. During flood stage a considerable portion of the town is
<br />susceptible to flood damage. The intent of this study is to develop
<br />maps and water surface profiles showing flood lines and elevation that
<br />might be expected from the 500 year, 100 year, 50 year, and 10 year
<br />frequency events. Maps are on a scale of 1 inch equals 200 feet with
<br />2.0 feet contour intervals.
<br />
<br />HYDROLOGY
<br />
<br />The hydrology phase of this study includes the development of peak
<br />discharge values for various desired flood frequencies at selected
<br />locations.
