Lock 19 Acoustic Study

Pentagon News — Fri, 30 Aug 2024 21:13:00 GMT

Invasive fish species, such as Bighead and Silver Carp, jeopardize aquatic ecosystems and affect the recreational uses of our nations’ waterways. The Invasive Carp Regional Coordinating Committee (ICRCC) is the Federal and State workgroup with the mission to prevent invasive fish from reaching the Great Lakes. Though not directly connected to the Great Lakes, the ICRCC identified Lock and Dam 19 on Mississippi River as an ideal test site for the Underwater Acoustic Deterrent System (uADS) because of its similarity to Brandon Road Lock and Dam. Both dams have a water surface elevation change greater than 35 feet, active commercial navigation, and a style of dam that forces all fish to pass through the lock to get upstream.

Illinois Waterway Dredged Material Management Plan (DMMP)

Pentagon News — Fri, 30 Aug 2024 20:01:00 GMT

The Illinois Waterway Dredged Material Management Plan (DMMP), part of the Dredged Material Management Program, is a study to evaluate and identify dredged material placement sites to accommodate the Corps’ dredging needs. The study area includes the Illinois Waterway (Rock Island District’s Portion), which extends 211 river-miles from Lockport, IL, downstream to LaGrange, IL. The Rock Island District’s portion covers 6 lock and dam sites and annually dredges many locations.

The project features would be located entirely on federally owned land that forms part of the Upper Mississippi River National Wildlife and Fish Refuge. The area consists of backwater lakes, sloughs, flowing channels, and impounded water residing over historically flooded islands and remnant islands. The lower section of Pool 13 is located in a valley that is 1.5 to 4.5 miles wide and contains few land masses.

Upper Mississippi River and Illinois River Flow Frequency Study

Pentagon News — Fri, 30 Aug 2024 16:07:00 GMT

The current Upper Mississippi River and Illinois River flow frequency study, completed in 2004, was created using a period of record ending in 1998. Since then frequent and record setting major floods have occurred. The flood of 2019 was not only historic with regards to flood heights, but also in its duration. The Mississippi River was above flood stage at Cape Girardeau for 145 days. In addition, many communities between Dubuque, Iowa and St. Louis, Missouri have experienced the majority of their top 10 flood crests in the past 20 years. Significant flooding on the UMR occurred in 2001, 2008, 2011, 2013, 2014, 2018, and 2019. The Illinois River has experienced the same unprecedented flooding. At Peoria, IL (on the IWW), 5 of the 10 highest flood crests have occurred since 1998; including the record crest in 2013.

Regional Flood Risk Management

Pentagon News — Fri, 30 Aug 2024 16:00:00 GMT

In recent years, the Upper Mississippi River watershed has experienced more frequent flooding with higher stages, particularly in the last ten years with major floods occurring in 2008, 2010, 2011, 2013 and 2014.

Pentagon News — Fri, 30 Aug 2024 14:54:00 GMT

Currently, there is no systemic flood risk management plan for the Upper Mississippi River. This uncoordinated flood response ultimately transfers risk to several areas, often without their knowledge. This watershed assessment will collaboratively develop an FRM strategy for UMR basin with an interagency team (Federal & 5 states).
