<br />28 THE ARKANSAS RIVER FLOOD ,O!....!'yNE 3-5, 1921.
<br />
<br />The difference is due chiefly to tlie ract that the :Union Depot is 750
<br />feet upstream from the river gage and 1,700 feet away from the river.
<br />A line of levels between high-water marks on the Victoria Avenue
<br />bridge, in line with the Union Depot, and the Main Street bridge
<br />showed a difference of 2.1 feet. The remaining difference is proba-
<br />bly due to the fact that the water surface at the Union Depot was
<br />higher than at the river, 1,700 feet distant, as shown by level Iines ron
<br />after the flood.

<br />The data covering the rise ~om the Dry Creek flood in the early
<br />morning of June 3 were taken from the continuous chart on the re-
<br />cording gage shortly before it was destroyed. Data. for the remainder
<br />of the time were obtained by the State engineer's office from several
<br />reliable sources. - .
