Location/Description
|
Construction of a series of locks and dams on the Upper Mississippi River created the 9-foot navigation channel.
Over the decades, the lock and dam system has, in general, reduced habitat diversity and resulted in a loss of aquatic vegetation on the impounded portion of the Upper Mississippi River system.
River resource management agencies and the public have expressed a growing interest in summer drawdowns of the navigation pools to promote growth of aquatic vegetation. A drawdown of Pool 8 was implemented during the summers of 2001 and 2002. Monitoring results indicate that the drawdowns were very successful in establishing aquatic vegetation. After 3 years of planning, the St. Paul District, in cooperation with the Water Level Management Task Force of the River Resources Forum, implemented a drawdown of Pool 5 in 2005.

|
Status
|
The Pool 5 drawdown was a maximum of 1.5 feet at the dam. It had a very positive vegetative response and encountered no major problems. Some concerns were reported regarding navigation and recreational access. Some mussel mortality was observed. An extensive monitoring effort used funds from the Navigation and Ecosystem Sustainability Program (NESP). A second year drawdown in Pool 5 began on June 12, 2006, but it was terminated on July 9 as a result of main channel conditions and low river flows. Final reports on vegetation response and a pool-wide mussel population estimate were received in early 2007. Monitoring showed a dramatic increase in emergent aquatic vegetation on more than 1,000 acres, a primary objective of the drawdown. Positive impacts on waterfowl such as ducks and swans were observed. Water clarity improved in many areas of Pool 5. Native vegetation created during the drawdowns in Pools 8 and 5 still persists in 2009.
A “minor” drawdown of Pool 6 was planned for 2009, but it had to be postponed because of low river flows. It will be attempted again in 2010 using O&M funding and authority if river flows allow. Depending on NESP funding levels, a water level management program will be initiated in 2010 under NESP for Pool 3.
|
The St. Paul District water level management program was named one of the 2007 Seven Wonders of Engineering by the Minnesota Society of Professional Engineers and won the Chief of Engineers Environmental Honor Award and USACE Design Team of the Year Award in 2008.

|
Authority
|
The Rivers and Harbors Act of 1930, which authorized the 9-foot navigation channel on the Upper Mississippi River, provides the authority for this work under O&M.
NESP was authorized in the Water Resources Development Act of 2007; it included provisions for water level management.
