Course Description

327-An Introduction to Pond and Lake Dredging

This course is designed to be an introduction into the planning, assessment, design and execution of dredge projects in inland waterways of Ponds and Lakes (coastal waterbodies that are tidally influenced will need to be approached differently). These bodies of water are an incredible resource in our country, they are sources of our drinking water, they provide flood storage and recreational opportunities, and are an integral part of our landscape.

There are numerous influences that affect the quality of our Ponds and Lakes, from development within the watershed, changes in environment and water levels (floods and droughts), and aging infrastructure (both on the inputs and the outlet/control structures). All of these influences may result in diminished water quality, invasive aquatic species, and sedimentation and infill of the waterbody. Dredging is an effective approach to counteract these negative effects on the waterbodies and that's what we will discuss in this course. It is important to note that dredging may help reduce the negative impacts of the past, but it should also be paired with compatible projects to reduce those impacts from the future, including stormwater management treatment strategies, invasive species monitoring, and other strategies, which will not be covered in this course.
