River Sand has a long history of working with engineers to develop a plan for dredging projects. One of the first steps in analyzing the need to dredge your lake may be to determine depth, location, and volume of sediment with a bathymetric or sediment survey. However, in most cases dredging is an effective solution to the problems listed above and many others. Sometimes dredging costs can outweigh the benefits of performing the work, deeming it unfeasible to dredge from a cost-benfit perspective. For example, very dirty water with a red color may contain high turbidity (suspended solids) but may not mean that there is enough sediment. River Sand can help confirm that dredging may be the correct solution for the problem. Discharge parameters are over the permitted limit.

The water is very turbid, turning brown or red in color.

The water depth is too shallow for boats and swimming.

Aquatic weed growth has become overwhelming.

Sediment is preventing flow throughout your pond.

Sediment is visible and above the water surface of your lake, pond, or lagoon.

One of the first questions anyone with a lake, pond, or lagoon should ask is, “Do I need to dredge?” In most cases, the problem is evident and creating a real issue for example:
