Service: Sediment Investigation & Removal
What is Sediment Build Up and Why Do I Need A Sediment Investigation?
All lakes and ponds have a natural life span and fill up with sediment over time. Sediment accumulation can be accelerated by shoreline erosion, runoff, or the seasonal buildup of organic material like submerged aquatic plants and leaves from trees. This can be fixed with a lake management plan. Eventually, lakes and ponds in Illinois and Wisconsin need to be dredged in order to maintain their intended use, whether its recreation or stormwater storage.
What Does A Sediment Investigation in Illinois/Wisconsin Involve?
A sediment investigation tells us how much sediment buildup there is in your lake or pond. It includes a bathymetric survey, which is an underwater topographical survey of the bottom of water body. It involves measuring the depth of water and the amount of sediment present before we reach the original, hard bottom. We collect data points throughout the waterbody using either sonar or sediment probing poles, or both, depending on conditions, and GPS track data collection points for future reference. We use ESRI ArcMap software to create bathymetric, sediment thickness, and total depth maps and to calculate sediment volumes in order to make recommendations on how much sediment, if any, needs to be removed.
What Occurs During Dredging?
When a sediment investigation reveals that your lake or pond has an unhealthy accumulation of sediment, we typically recommend dredging. Dredging can be done either hydraulically or manually. Access is a big factor in determining the most appropriate dredging method for your site, and luckily, our equipment is capable of fitting in even the most congested areas of Illinois and Wisconsin
Hydraulic dredging uses suction and is especially effective when removing loose muck. Hydraulic dredges work like a vacuum, sucking up a mixture of sediment and water and transferring it through a hose into, most often, a dewatering bag. The sediment stays in the bag and clean water returns to the waterbody. Hydraulic dredging is limited by the onshore space to keep the dewatering bag(s). Hydraulic dredging is especially cost-effective when there is a use for the dredge material on site. Our Truxor mini-hydraulic dredge is great for dredging ponds and small lakes or doing maintenance dredging on larger bodies of water.
Mechanical dredges work by mechanically digging sediment from the bottom using an excavator with a bucket. We use a long-reach excavator when working from the shore. Material is scooped from the bottom and into trucks which is either repurposed on-site or transported to the nearest disposal site. We also have a specialized amphibious excavator which allows us to work farther away from land or in difficult conditions in Illinois and Wisconsin where a traditional excavator would sink. In this case, the material is scooped into a barge or sled and then transferred into trucks and hauled away.
