<br />The Boxelder Creek Watershed covers an area of ZSl square miles or
<br />160,640 acres in parts of Larimer and Weld Counties, Colorado and
<br />Albany and Laramie Counties, WyOlling. The watershed is about 32 miles
<br />in length and averages about 8 miles in width. It consists of Boxelder
<br />Creek heading in the northwestern part of the watershed being joined on
<br />the east by several southerly flowing tributaries; Sand Creek, Rawhide
<br />Creek, Coal Creek and Indian Creek, f01'llling a ccmnon alluvial flood plain
<br />which continues south to its confluence with the Cache la Poudre River
<br />~bout.3 miles southeast of Fort Collins, Colorado. The Cache la Poudre
<br />1S tnbutary to the South Platte River in north central Colorado. About
<br />19 percent is i:rrig!lted cropland, 48 percent is grassland, II pel"(:ent is
<br />brushland,. 8 ~rce~t is forest land, 8 percent is non.i:rrigated cropland,
<br />1 percent 1S w1ldllfe areas and 5 percent is miscellaneous. About 92
<br />percent of the watershed is private land and about 3 percent is State
<br />land. Land values per acre are $800 for irrigated cropland $100 for
<br />non-irrigated cropland, $50 for rangeland and $1,500 for ag;icultural

<br />The project objectives are to reduce damages to agricultural land and
<br />crops, irrigation facilities, farmsteads, highways, embankments and
<br />bridges from 10-year frequency sto~ or larger and to the town of
<br />Wellington from the 100-year frequency stoms. Consideration is to be
<br />giVen to measures that will preserve, enhance or protect watershed values
<br />and natural beauty and prevent environmental pollution,
