What is Detention Pond Dredging in Michigan?

Introduction
Detention pond dredging involves the removal of accumulated sediment, debris, and organic matter from the bottom of the pond by mechanical means. Over time, stormwater runoff introduces soil, nutrients, and pollutants that settle at the pond’s bottom, gradually reducing depth and capacity. Dredging restores the pond’s original depth, enhancing its ability to manage stormwater, control runoff, and prevent unwanted overflow and algae growth.

Our Detention Pond Dredging Process:

Assessment and Planning
We start with a thorough assessment, measuring sediment depth, inspecting inflow and outflow structures, and evaluating water quality. This allows us to develop a plan that meets the specific needs of your detention pond.
Permitting Assistance
Dredging projects may require permits, especially for detention ponds near natural water bodies. Schlicht Ponds has extensive experience navigating Michigan’s EGLE permitting process and will guide you through it, ensuring full compliance with state regulations.
Dredging and Sediment Removal
Using specialized dredging equipment, our team removes sediment, debris, and excess nutrients from the pond’s bottom. This process restores capacity and improves stormwater management. For detention ponds with limited access, we may use our Dino 6 Dredge to get to those hard to reach areas.

Detention Pond Structure and Outlets

Detention basins are typically located where new residential, commercial, and industrial developments replace open land and forest with impervious surfaces like parking lots, roads, and rooftops. As stormwater runs off these surfaces, it enters streams and rivers at a much faster rate, leading to stream bank erosion and potential downstream flooding. Detention basins are crucial in controlling this runoff, preventing flooding, and improving water quality.

Proper structure and outlet design are essential for detention pond functionality:

Outlets: Designed to control water release, outlets help manage flow rates to reduce flooding and prevent erosion downstream. These can become clogged by sediment buildup and other debris if not properly maintained.
Inflow and Outflow Pipes: These pipes regulate water levels, ensuring efficient stormwater flow and preventing overflow.
Spillways and Control Structures: These components direct excess water safely away from the pond, helping to prevent uncontrolled flooding.
Erosion Control Measures: Reinforcing the pond structure helps prevent sediment displacement and maintains stability, keeping the basin effective over time.

What Type of Maintenance Is Needed for Detention Ponds?

Detention pond maintenance needs vary based on factors like stormwater runoff volume, sediment accumulation rates, and nearby land use. If a detention basin isn’t maintained regularly, this can lead to costly repairs in the future. Generally, detention ponds may need dredging every 5–10 years. Regular inspections help determine when dredging is required to maintain optimal function.

Michigan.gov Recommended Detention Basin Tasks and Schedule:

1. Sediment Inspection and Removal
Sediment accumulation should be inspected annually, with removal typically required every 5-10 years.

2. Debris and Trash Removal
Inspect and clear dead vegetation and debris in early spring, fall, and after major storms. Cleaning ensures unobstructed water flow and helps maintain the pond’s capacity.

3. Erosion Control
Erosion on banks and pond bottoms should be inspected after major storms, with reestablishment of vegetation as needed to stabilize soil and prevent sediment displacement.

4. Vegetation Management
Reestablish vegetation on eroded slopes, remove dead plants, and manage invasive species like purple loosestrife annually or as needed.

5. Structural Inspections
Annual inspections of structural elements (like pipes, rip-rap, and spillways) ensure that the pond functions correctly. Regular checks for obstructions and structural damage help maintain the pond’s stormwater capacity.

6. Record Keeping
Keep detailed records of all inspections, maintenance activities, and costs. These records help track the condition of the pond over time and support future planning.

Signs Your Detention Pond Needs Dredging:

Reduced Pond Depth: A noticeable decrease in depth is often due to sediment buildup.
Frequent Overflow and Improper Drainage: Detention ponds losing capacity may overflow more frequently, especially after storms.
Poor Water Quality and Increased Algae Growth: Murky or foul-smelling water suggests a buildup of organic matter and pollutants. Excess nutrients in the sediment can lead to algae blooms, impacting water quality and the pond’s appearance.

Detention Ponds for HOAs and Businesses

Detention ponds are critical stormwater management solutions for HOAs and subdivisions, helping to manage runoff and prevent localized flooding. These ponds protect residential properties, roads, and landscaping from water damage after heavy rainfall. Homeowners’ Associations and business owners are responsible for maintaining these detention basins to ensure they function effectively. Without proper maintenance, detention basins lose their ability to control flooding on private property and prevent pollutants—such as sediments, fertilizers, and pesticides—from entering nearby creeks and streams.

Schlicht Ponds collaborates with HOAs and community organizations to design, dredge, and maintain detention ponds that meet stormwater regulations while enhancing the visual appeal of the community. Our services ensure that detention ponds are safe, functional, and seamlessly integrated into the neighborhood.
