Dam Bridge & Gate Painting – Lower St. Anthony Falls Through Lock and Dam 10

The St. Paul District operates and maintains 13 locks and dams from Upper St. Anthony Falls in downtown Minneapolis, Minnesota, to Lock and Dam 10 in Guttenberg, Iowa. Each lock and dam is a critical step in the "stairway of water" that makes navigation possible between Minneapolis and St. Louis, Missouri. These facilities are aging structures, with locks and dams 2 through 10 originally constructed in the 1930s. These sites include a dam bridge and varying numbers of dam gates. The moveable dam gates are one of the most critical system components because they control pool elevation for navigation, flood control and environmental purposes.

Levee System Evaluations for the National Flood Insurance Program

FEMA administers the NFIP program, which focuses on the 1-percent annual chance exceedance flood, also referred to as the 100-year or base flood. The FEMA 100-year flood is a flood insurance standard, not a public safety standard. A levee system evaluation determination by the Corps is a technical finding that, for the floodplain in question, there is a reasonable assurance the levee system will exclude the 1-percent annual chance exceedance flood (or base flood) from the leveed area based on the condition of the system at the time the determination is made. As part of its levee system evaluation process, the Corps will examine and report on elements of residual flood risk and public safety.

Mississippi River Locks and Dams 2–10 Guidewall Crib Repairs

Guidewalls are integral to each of the Mississippi River Locks and Dams 2 through 10. Guidewalls are long extensions of the lock walls, in either the upstream or downstream direction, that are parallel to the lock wall. These walls serve primarily to guide the long tows into the lock and to provide mooring facilities for tows too long to be accommodated in a single lockage. The guidewalls are constructed of multiple 35 to 40 feet length concrete monoliths with rock filled timber cribs beneath and behind them.

Mississippi River Locks and Dams 2–10 Non-Structural Embankment Repair

Non-structural embankment repair projects at Locks and Dams 2 through 10 will address restoring embankments to meet current design standards. Most dam embankments are currently protected from the erosive forces of water by a layer of riprap placed along the embankment’s length. When the riprap eventually erodes, the embankment itself will erode if more protection is not added. The U.S. Army Corps of Engineers has designed and placed berms and small islands to assist in reducing wave action and wind fetch within pools created by the locks and dams. Reducing these forces increases the longevity of the embankment protections.

Tribal Partnership Program (TPP): Lac Courte Oreilles Muskellunge Spawning Habitat Restoration

Located in Sawyer County, Wisconsin, Lac Courte Oreilles (LCO) is a series of lakes that was once a highly productive wild rice water with copious amounts of fish. Within LCO, Musky Bay produced the most wild rice and served as the primary spawning habitat for muskellunge, which are native to LCO. The lake has been known for producing trophy-size fish, including a world record. Presently, due to eutrophication, the wild rice has almost completely disappeared and fish are disappearing within the boundaries of the LCO Reservation. Eutrophication, which occurs when a body of water becomes overly enriched with nutrients, has caused a dense growth of undesirable plant life and fish kills.
