Today's photo features Lock and Dam 11 on the Mississippi River between Dubuque, Iowa and rural Grant County, Wisconsin. This particular photo was taken from Eagle Point Park in Dubuque which is located on the bluffs far above the waterway and offers great vistas of the neighboring state, the nearby landscape and the operation of the lock and dam. And, since some details regarding the dam interest me, I decided to share a few tidbits. According to information posted on the web by the US Army Corps of Engineers, the average lift is 9.4 feet with the maximum of 11 feet; filling or emptying the lock chamber takes about 7 minutes; and water coming from Lock and Dam 10, in Guttenberg, Iowa, takes 9 hours to reach Lock and Dam 11.
