<p>The lamented yes, but sometimes arises when people argument around known facts.</p> <p>[quote user="Murphy Siding"] I dunno. I don't see where they would have thought the Little Rock River was a threat that might cause a derailment to happen further down the line- which it didn't. All the low lying farmland in that area tends to flood every spring to some extent; nothing new there.[/quote]</p> <p>I think we agree that there was a high water. From the facts I say it was an unusal high water. Was it high enough to be of concern for BNSF? Apperently not. Should it have been? My personal opinion is yes.</p> <p>What did I find:<br />- Rock River gage 10 mi upriver exceeded Major Flood Stage 16 hrs before accident</p> <p>- Rock River gage at Rock Valley downriver 1.5 ft below record level 3.5 hrs before accident</p> <p>- Rock River gage at Rock Valley downriver: Discharge of June 22, 2018 only exceeded twice in the last 70 years (see my post at top of page)</p> <p>- Rock River gage 10 mi upriver had a discharge of 13,000 cubic feet per second.</p> <p>- Of the 35,000 cfs at Rock Valley only 13,000 cfs came from the Rock River itself, according to the map the balance came most likely from Little Rock River.</p> <p>It is for sure not a yearly high water.</p> <p>If BNSF realized this or not we don't know. At least the information was publicly available.<br />Regards, Volker<br /><br /></p>
