SHELBYVILLE, Ill. — Dredging work continues on Lake Shelbyville as crews with the U.S. Army Corps of Engineers press forward with a sediment removal project aimed at improving navigation and waterway conditions on the reservoir. Officials are advising recreational boaters and other lake users to exercise heightened caution around active work zones as operations remain underway.
Installation of Floating Dredge Pipeline
The Corps confirmed that a floating dredge pipeline has been installed across sections of the lake to support the ongoing project. The installation was originally intended to be submerged, but current water levels—typical of winter pool conditions—are too low to permit safe passage of vessels over an underwater line. As a result, the pipeline will remain on the surface for the present phase.
Water Level Limitations and Surface Pipeline Placement
The floating line runs from the dredging apparatus to designated sediment placement areas. It is supported by foam-filled floats and secured in place with anchors, authorities say, to minimize movement and maintain stability during operations. To enhance visibility and protect the public, the entire length of the pipeline will be clearly marked with warning buoys and lighting.
Warning Buoys, Lighting, and Visibility Features
White buoys bearing the label “Danger Dredge Pipeline” will be placed at roughly 30-foot intervals along the pipeline. Each of these markers is equipped with amber, solar-powered flashing lights visible for up to two miles in clear nighttime conditions. Additional red buoys with red lights will delineate the ends of approved channel crossing areas.
In addition to the buoy markers, the dredge itself will be outfitted with prominent warning signage and lighting. Officials say the vessel’s limited maneuverability makes such precautions essential for safe navigation. All-around white lights will be displayed at night to ensure the dredge’s position is visible to approaching watercraft.
Pipeline crossings are not being installed at this time due to insufficient depth. Still, Corps representatives stated that as lake levels rise toward the summer pool, they will reassess whether crossings can be safely implemented. Any such changes will be communicated to the public.
Recreational users are urged to respect posted warnings, maintain a safe distance from dredging equipment, and follow all navigation guidelines. For ongoing project updates, the Corps suggests consulting the Lake Shelbyville U.S. Army Corps of Engineers social media channels or contacting Corps offices directly.
