<br />THE FLOOD AT PUEBLO.

<br />.Tune 3, and bccause the area immullted.was so'wiele it waR impossible
<br />to make discharge measurements during the peak flow. A itel' the
<br />flood the United States Geological Survey determined the maximum
<br />discharge as 103,000 second-feet. (See p. 20.)
<br />An idea of the unprecedented discharge of the river during the
<br />flood is given by the following table showing the available records of
<br />mllximum discharge:

<br />TOTAL DISCHARGE.
<br />
<br />,. . The recording; gage at Pueblo was destroyed by the flood, and no
<br />; continuous record of river height cxists. From the testimony of local
<br />jobservel's and fi-om high~water marks it has been possible to .con-
<br />struct a fairly complete aha accurate hydrograph of the Arkl1nsllS at
<br />. Pueblo from June 2 to li."(fig. 1). The most complete record of the
<br />river during the time of the principal rise' was that obtained hyMr.
<br />B. Milton Stearns, assistant chief train dispatcher of the Denver &
<br />Rio Grande Railroad. As the water rose in the Union Depot the
<br />. distance to the water surface from a flxed point was measured with l1.
<br />level rod nnd the time noted. This was done at frequent intervals
<br />f~om 9 p. m. on the 3d to 7 a. m. on the 4th, the period during which
<br />the river was above the floor of the Union Depot. The reference
<br />. points used were .latercomiected to the City . datum by level, and "tpe-.
<br />maximum stage was found to'be at 4,684.75 f€!it above the sea. TIie'
<br />maximum stage at' the.triVer ~5l! .i-t {fie' lVi"ain Street bridge ~s
<br />determined after the' ffood, !tom a well-defined watermark on tJje
<br />outside of the new'CityhlzIl.150 feet distant. This mark was fouIld
<br />to be 24:.66 feet above the zero 'of the gage, or 4:,681.70 feet abore the
<br />sea, 3.05 feet lower thim thehtaximum observed at the Unipn Depot.
