    • Data Release for Lock 19 Underwater Acoustic Deterrent System (UADS) Study: Interim Project Update

    Metadata Updated: January 21, 2026

    The Underwater Acoustic Deterrent System is an experimental deterrent that utilizes underwater sounds to deter invasive carps. An experimental deployment and evaluation of a UADS is currently being conducted at Lock 19 on the Mississippi River, near Keokuk, Iowa. This dataset includes information derived from two telemetry arrays (i.e., 307 kHz HTI and 69 kHz VEMCO) deployed at and around Lock 19 to evaluate fish movement and response to the UADS in 2021 and 2022. Silver Carp, Bighead Carp, Grass Carp, and a variety of native fish species were tagged and monitored with the telemetry arrays.
