<br />to mnke dlscllal'ge mensurements durIng the peak now. A iter the
<br />flood the United Stl\tes Geological Survey determined the maximum
<br />discharge as 103,000 second-feet. (See p. 20.)
<br />An idea of the unpreeedente(l discharge of the river during the
<br />flood is given by the following table showing the available records of

<br />;observers and #,om high~w~ter marks it has been possible to ..con-
<br />struct a fairly complete ana accurate hydrograph of the Arkansas at
<br />'Pueblo from 'June 2 to a:'(.fig. 1): The most complete record 'of the
<br />river during the time of the principal rise' was that obtained by}tIr.
<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 />. di$nee to the water surface from a fixed point was measured with II.
<br />.l~vel rod and the time noted. This was done at frequent intervnIs
<br />from 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 iised were ,later 'connected to the City datum .bi lev,el, and ~t~e--
<br />m~xiJnum stage was found to'be at 4,684.75 ffft above the sea. THe.
