The spillway is 7000 feet long (2134 meters for non-Imperials).There are 350 "bays" that can be opened with each bay 20 feet wide (6.1 meters).The maximum flow capacity is 250,000 cubic feet per second of water flow (you can convert this to m3/s as a homework question).The floodway (the part of land that becomes a temporary river) is 5.7 miles long.
