<br />starting at an elevation of 6,000 feet near the
<br />headwaters to 4,700 feet at the mouth. The
<br />separate ephemeral (whieh often TIm dry in
<br />the summer) streams, Wild Horse and Dry
<br />Creek, originate in the foothills of the frontal
<br />range northwest of Pueblo,
<br />
<br />Dry Creek is a north-bank tributary which
<br />flows south just within Pueblo's eastern
<br />boundary, This watershed spans a distanee of
<br />5.5 miles from the headwaters to the mouth.
<br />Its drainage area eovers only 5.4 square
<br />miles, Dry Creek is an ephemeral stream,
<br />which originates at the southern extremity of
<br />Baculite Mesa in the high plains northeast of
<br />Pueblo. It flows in a southerly direction to
<br />discharge into the Arkansas River just east
<br />of the eity limits,
<br />
<br />Goodnight Arroyo is an ephemeral south-
<br />bank tributary of the Arkansas River that
<br />originates on the high plains southwest of
<br />Pueblo, The arroyo is 4.9 miles long, and its
<br />longest branch originates just over one mile
<br />south of State Highway 78 and then
<br />meanders in a northerly direetion, Just
<br />outside Pueblo's western boundary the arroyo
<br />passes under Bessemer Ditch and State
<br />Highway 96 (Thatcher Avenue) and turns
<br />west toward the Arkansas River. The
<br />drainage area eovers 5,9 square miles, and
<br />elevations range from 5,330 feet at the
<br />headwaters to 4,708 feet at the Arkansas
<br />River eonfluenee,
<br />
<br />The Hueifano River covers a drainage area
<br />of 1,876 square miles, stretching 90 miles in
<br />length, The headwaters begin at an elevation
<br />of about 10,500 feet, where the stream is
<br />perennial, Then the river flows north and
<br />east through the foothills and onto the plains,

<br />Here irrigation diversions dry out the stream
<br />in the summer by the time it reaches the
<br />Arkansas River near Boone,
<br />
<br />Salt Creek is a right bank tributary with the
<br />eonfluenee loeated in the southeast eorner of
<br />the City of Pueblo. The stream's headwaters
<br />originate in the foothills about eight miles
<br />south and ten miles west of the eity, The
<br />Salt Creek watershed contains 37,2 square
<br />miles, which is minor in regard to size but it
<br />is important in that it flows through the
<br />residential and major industrial areas of
<br />southeast Pueblo, The stream stretches about
<br />18 miles long, the upper 5 miles of which
<br />are considered to be intermittent, At its
<br />eonfluence with the St. Charles River Flood
<br />Ditch it reeeives a maximum flow of
<br />approximately 635 cubic feet per seeond
<br />(cfs- see box below) diverted from the St.
<br />Charles River. This water provides a base
<br />flow in Salt Creek during the spring and
<br />summer months, A few miles downstream
<br />from its junction with the Flood Ditch, Salt
<br />Creek flows into a series of reservoirs (water
<br />from the ditch and creek is stored here and
<br />used by CF & I in their industrial processes),
<br />through CF & I, and fmally into the
<br />Arkansas, Almost all of the Salt Creek
<br />channel is located on land owned by CF &1.
