Lake Carroll Sedimentation Pond 3 Dam, located in Georgetown, Illinois, was completed in 1989 and serves as a private debris control structure along the Tributary East Fork Plum River. This earth dam stands at a height of 23 feet and spans 510 feet in length, with a storage capacity of 80 acre-feet. While the dam's primary purpose is debris control, it also serves as a vital infrastructure for flood prevention and water resource management in the Carroll County area.

Managed by the Illinois Department of Natural Resources, this low hazard dam has a moderate risk assessment rating and is subject to regular state inspection, enforcement, and permitting. With uncontrolled spillways and outlet gates, the dam's design and construction were overseen by FEHR-GRAHAM & ASSOC. Despite its low hazard potential, the structure plays a crucial role in maintaining water quality and flow in the Plum River watershed, benefiting both local ecosystems and communities.

As a key component of the local water resource infrastructure, Lake Carroll Sedimentation Pond 3 Dam not only provides debris control but also contributes to flood prevention efforts and water quality maintenance. With its moderate risk assessment rating, this earth dam serves as a reminder of the importance of proper dam management and maintenance for the continued protection of natural resources and public safety in the Carroll County area.
