     "text": "This study builds on deterrent testing in the laboratory, ponds, and field, as well as designs and models for an UADS as part of the USACE-developed Tentatively Selected Plan for Brandon Road Lock and Dam. Because one UADS design is not appropriate for all site applications, the design for this project (bottom mounted acoustic transducers, recessed to withstand navigation hazards) includes a bottom-mounted speaker array designed to operate in the turbulent environment created by lock discharge directed into the lock approach channel. The study design considered the collective extensive multiagency experience evaluating bigheaded carp passage at LD19, high head dams in the upper Illinois waterways, and other dams."

     "text": "Previous studies and experience have demonstrated that some locks and dams operate as bottlenecks or pinch points for invasive carp populations and range expansion because of unique hydraulic conditions and operations at these dams. As compared to dams without these unique conditions, pinch-point dams restrict upstream fish passage to the lock chamber and result in limited (but not zero) upstream fish passage at most river flows. This upstream passage limitation at these dams make them ideal for deployment and testing of an experimental underwater acoustic deterrence system (UADS). Lock and Dam 19 (LD19) on the Mississippi River near Keokuk, IA is a populations pinch-point dam for bigheaded carp in the UMR. We designed and installed an UADS at this location from 2020-2021 in partnership with the U.S. Army Corps of Engineers (USACE) Engineer Research and Development Center-Environmental Laboratory (ERDC-EL). In partnership with the USACE, USFWS, and state natural resource agencies, we initiated an evaluation of the UADS in spring of 2021 to determine its effects on upriver-swimming invasive carp and native fishes. This evaluation will continue through fall of 2024."
