28 THE ARKANSAS RIVER FLOOD OF JUNE 3-5, 1921.. The difference is due chiefly to tKe"fact that the Union Depot is 750 feet upstream from the river gage and 1,700 feet away from the rivero A line of levels between high-water marks on the Victoria Avenue bridge, in line with the Union Depot, and the Main Street bridge showed a difference of 2.1 feet. The remaining difference is proba- bly due to the fact that the wate.r surface at the Union Depot was higher than at the river, 1,700 feet distant., as shown by level lines run after the flood. 28 26 - - - I - I , - \ I I 1 \ f\ I - \ f\ \ - : '- /'. \ \ - , "- j...J '-- 7 \ J ........ - - - June 2 June 3 JUDie 4 .
