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.

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.

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.
