As a dredge operator, you remove sand, gravel, and other forms of sediment from lakes, rivers, streams, canals, and other waterways. You typically excavate these areas so that boats and barges can use them. While you usually maintain navigable waterways, your responsibilities can also include dredging to mitigate flood risks, reclaim shoreline or wetlands, or assist in engineering projects. In this career, you operate dredge systems that consist of hydraulic pumps, anchors, suction devices, and measuring instruments to guide each project. Your duties include monitoring progress and deciding where to place the dredging equipment for optimal efficiency.
