Common Problems Affecting Pond Function: Invasive Species

What are invasive plants? While inspecting your stormwater detention pond, you may come across invasive plants crowding the area. Invasive plants are non-native plants that are introduced into the environment and often harm the local ecosystem.   What’s the issue? When invasive species find their way into stormwater detention ponds, they can inhibit stormwater pond function. Invasive plants like giant reed/phragmites, cattails and reed canary grass can fill in a detention pond by trapping sediment. As detention basins are filled…

Common Problems Affecting Pond Function: Shoreline Erosion

What is shoreline erosion? During inspections of your local stormwater detention pond, you may notice signs of shoreline erosion. Common signs of a deteriorating shoreline can include: Loose soil around the shoreline Soil collapsing into the water causing murkiness Steep shoreline bank Why is Shoreline Erosion a Problem? When soil erosion occurs, the loose soil particles build a layer of sediment in the pond and make the water murky. Over time the extra layer of sediment in the pond can…

Common Problems Affecting Stormwater Pond Function: Blocked Inlet and Outlet Structures

What are Inlet and Outlet Structures? The inlet and outlet structures of your stormwater detention pond are the most crucial component in maintaining the water level of your pond to prevent flooding in your neighborhood. The inlet structure is where the pipe that collects stormwater run-off from impermeable surfaces such as roads, roofs, and sidewalks empties into the detention pond. The water gradually releases to local waterways through outlet structures. Sometimes inlet and outlet structures fill with trash, sediment, or…

5 Ways Homeowners Impact Detention Basins

During storms, water is usually absorbed into natural surfaces like soil and vegetation. However, if the stormwater lands on a hard surface such as sidewalks, roadways and rooftops, the stormwater cannot be absorbed and will run-off, likely to a nearby stormwater detention basin. Detention basins, or detention ponds, collect and store stormwater to prevent flooding and erosion of local waterways. These detention basins can be found near residential and commercial areas. They can create a beautiful environment for homeowners to…

Ways Homeowners Impact Detention Basins – Newsletter

Stormwater detention ponds are important for reducing flooding in your community. However, if detention ponds are not maintained, they can become unsightly and lose function. Homeowners Associations (HOA) are responsible for the maintenance of their stormwater ponds, but it is important to note that residents also impact the condition of detention basins. From lawn care to pet ownership, everyday choices can affect detention pond function, water quality, and aesthetic value.
