Devils Lake Levee, North Dakota
Location/Description
|
Devils Lake is a closed basin in semi-arid northeastern North Dakota. Depending on climatological patterns, the lake is subject to extreme variations in stage. High lake levels cause urban, agricultural, and transportation flood damages. The lake reached its highest recorded level (1449.20 feet) in May 2006 and has caused more than $300 million in flood related damages.
The levee system is about 8 miles long with a top elevation of 1460 feet above mean sea level. Although referred to as levees, the system was actually designed and constructed as a dam to hold back water for many decades. The Corps is currently working with the Federal Emergency Management Agency, the U.S. Geological Survey, and local officials to determine the level of protection that is provided by the levee elevation of 1460. Traditionally, the top 6 feet of the levee elevation serves as freeboard, or a safety factor to prevent waves or ice from splashing over it. Before the levees were built, snowmelt and rain runoff drained to the lake. Now, the interior drainage is routed to five pumping stations that pump the water over the levee.
|
Status
|
Work was essentially completed in December 2005 on the additional 3-foot raise that brings the levees to a top elevation of 1460. The project is monitored and maintained by the city with annual inspections by the Corps.
If the lake continues to rise, additional actions may need to be taken to protect the city of Devils Lake. The Emergency Supplemental Appropriation of 2007 included $5 million to plan and design the next levee raise. In the coming months the Corps of Engineers will work with the local community to identify possible solutions while minimizing impacts, and develop a strategy for implementation.
|
Additional
|
The initial levees were constructed in the 1980s to an elevation of 1445. By resolution dated June 17, 1996, the city formally requested emergency assistance from the Corps to raise the city's protection dikes an additional 5 feet to an elevation of 1450. On June 12, 1997, the city requested assistance in raising the levees to an elevation of 1457 to provide protection for a lake level of 1451. The project was approved under Public Law 84-99, Advance Measures Authority. A project cooperation agreement was signed on August 12, 1996, and amended on June 1, 1998, and August 3, 2004.
