Mississippi Headwaters Reservoirs Dam Safety Issues
Location/Description
|
The Headwaters Reservoirs' six control structures were constructed in the 1800s to aid navigation on the Mississippi River. They were no longer needed to support navigation with creation of the 9-foot channel in the 1930s, and no significant maintenance has been conducted at some sites for more than 50 years. As recreation grew in importance to the region's economy, the reservoirs' mission shifted to flood risk management and recreation.
Two of the dams are classified as having significant hazards, with potential for severe economic and environmental damage in the event of significant hydrologic events. These sites currently do not meet engineering criteria for significant hazard dams. Control is accomplished with antiquated wooden stoplogs, an operation that is considered unsafe by the Corps of Engineers' St. Paul District safety officer. The stoplogs are deteriorated and are unable to be removed in many cases. These problems have been recognized for several years but have not been addressed because of insufficient Operation and Maintenance funds. The costs for individual sites do not satisfy thresholds to qualify for alternative funding sources.
|
Status
|
A contract to remedy deficiencies at Winnibigoshish Dam has been completed except for approximately $25,000 in work in fiscal year 2009 to complete electrical work. Engineering and design work for Pokegama Dam near Grand Rapids, Minn., has progressed to support awarding a contract when funding is made available. Funding is not available to begin construction at Pokegama or engineering and design work on Leech Lake Dam in fiscal years 2008 and 2009 and is not anticipated in 2010.
|
Fiscal
|
The costs of upgrades range from $1 to $2.5 million at each site. In fiscal year 2009, $2.9 million is needed to fund the Pokegama Dam contract and conduct engineering and design for Leech Lake Dam. Funds for these activities are not included in the President's budget for fiscal year 2009.
