Lee County Conservation Board - CAP Sec 204

Pentagon News — Fri, 30 Aug 2024 21:02:00 GMT

Lee County Conservation Board owns and manages over 2500 acres of land forming a submerged island complex within Pool 19 of the Upper Mississippi River. Construction of a project that reduces wind fetch and turbidity in this area could result in habitat benefits to nearly 300 acres. Much of the benefit would result from improved aquatic vegetation and protection from wind driven waves. The team expects an improvement in habitat quality when construction is complete.

Dam Safety Program

Pentagon News — Fri, 30 Aug 2024 16:49:00 GMT

The purposes of a dam safety program are to protect life, property and the environment by ensuring that all dams are designed, constructed, operated and maintained safely and effectively.

Coralville Lake, Iowa

Pentagon News — Fri, 30 Aug 2024 16:40:00 GMT

Coralville Lake is a multiple purpose project providing primary benefits in flood control and low-flow augmentation with secondary benefits in recreation, fish and wildlife management, forest management, and water quality improvement.

UMRR Program – Lower Pool 13 – Phase II HREP

Pentagon News — Fri, 30 Aug 2024 16:26:00 GMT

The Lower Pool 13 Habitat Restoration and Enhancement Project – Phase II, part of the Upper Mississippi River Restoration program, is located approximately three miles upstream of the city of Clinton, Iowa. 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.

UMRR Program – Green Island HREP – Pool 13

Pentagon News — Fri, 30 Aug 2024 16:19:00 GMT

The existing forest is degrading at an alarming rate with numerous stressed and dying trees. The ox-bow lakes have lost much of their depth due to sedimentation and provide little fish refuge in the summer and winter. The pump system is old, inefficient and expensive to operate. The old drainage ditches are sediment filled to the point that a drawdown cannot be completed to regenerate high quality moist soil or emergent and aquatic vegetation. Elevated water tables on the Mississippi River proper are also adversely affecting floodplain forest composition and regeneration.

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.

UMRR Program – Beaver Island HREP - Pool 14

Pentagon News — Fri, 30 Aug 2024 16:05:00 GMT

Beaver Island is located along the right descending bank of the UMRS in the southern portion of Clinton County, Iowa. Lock and Dam 13 is located 5 miles upstream of the island system. The Project lands, part of the UMR National Wildlife and Fish Refuge, are federally-owned. The goals are to restore and protect aquatic, wetland, and floodplain forest habitats.

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.

UMRR Program - Pool 18 Forestry HREP

Pentagon News — Fri, 30 Aug 2024 15:58:00 GMT

The Pool 18 Forestry Habitat Rehabilitation and Enhancement Project, part of the Upper Mississippi River Restoration program, is located in portions of Louisa and Des Moines Counties in Iowa.

City of Dubuque Forced Sewer Main, Dubuque County, IA– CAP Section 14

Pentagon News — Fri, 30 Aug 2024 15:39:00 GMT

The city of Dubuque, Iowa, has two sanitary sewer mains, one thirty-inch and one forty-inch diameter, sanitary force mains and the Terminal Street lift station located adjacent to the Mississippi River in Dubuque County, Iowa. Loss of riprap protection along the length of the force main is threatening the safety and integrity of the forced main. Opportunities exist to reduce erosion and safety concerns through structural and non-structural measures.

Upper Mississippi River - Illinois Waterway System Navigation and Ecosystem Sustainability Program (NESP)

Pentagon News — Fri, 30 Aug 2024 15:22:00 GMT

NESP is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System (UMRS). NESP will improve system capacity and reduce commercial traffic delays through construction of 7 new 1,200-foot locks, mooring cells and switchboat implementation.

Upper Mississippi River Watershed Project

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).

Shoreline Management on Mississippi River

Pentagon News — Fri, 30 Aug 2024 13:45:00 GMT

In 1989, the Shoreline Management Plan (SMP) was developed and implemented as guidance for the management, protection and preservation of the Mississippi River's environment, while allowing a balanced use of the shoreline.
