stoplog
 n.— «When the levee was completed 10 years ago the only gap was the one created for the railway tracks. The tracks made floodgates impossible, so the solution chosen is what is called a “stoplog” system. This system consists of stacking aluminum I-beams in a horizontal position between two support slots constructed at the edges of the opening.…The beams, along with the cables to attach them to the backhoe, are kept safely locked at the levee. Seals are not attached to the stoplogs; however, plastic sheeting or sandbags could be used to reduce leakage through the stoplog closure structure.» —“Levee’s Stoplog System Is Tested To Ensure Public Safety If Flood Occurs” by Linda Kor AzJournal.com (Holbrook, Arizona) June 13, 2007.
