Understanding Natural vs. Problematic Foam in Streams, Channels, and Lakes If you spend enough time around streams, roadside ditches, or lakes, you will eventually notice patches of foam collecting along the edges or drifting in slow-moving water. For many people, the immediate assumption is that th…

A Look at the English Brook Delta in Lake George, New York Sediment is a natural part of any water system, but when it accumulates faster than a system can handle, it begins to change the waterbody in ways that are both visible and subtle. Excess sediment alters water clarity, transports nutrients, …

Culverts are often out of sight and, as a result, out of mind, until they fail. When they do fail, the consequences can range from nuisance flooding to full roadway washouts. One of the most overlooked factors in culvert performance is vegetation management. Too little control can obstruct flow and …

For decades, the ideal suburban yard has been defined by a single image, a uniform carpet of bright green grass, edged with ornamental shrubs and kept pristine through fertilizers, pesticides, and frequent watering. It is neat, predictable, and widely accepted as a symbol of care and success. But fr…

Municipal governments are often viewed as stewards of water quality, yet many of their routine, necessary operations can unintentionally contribute pollutants to the stormwater system. Unlike wastewater, which is treated before discharge, stormwater typically flows untreated into nearby streams, riv…

Stormwater outfalls are the final point where a drainage system releases water into a receiving body such as a stream, river, wetland, or lake. Because they sit at the end of the system, they are often overlooked until a visible failure occurs. When an outfall collapses or erodes, the consequences c…

Open channel outfalls occupy a unique space in stormwater infrastructure. They are simple in appearance, often nothing more than a vegetated swale or gently graded channel, yet when properly designed they function as treatment systems, flow control measures, and in northern climates even snow manage…

Dry weather outfall screening is one of the most effective and defensible tools available to municipal stormwater programs for identifying illicit discharges. Under MS4 permit requirements associated with the Clean Water Act and the NPDES stormwater program, municipalities are required to implement …

Lake George in upstate New York is often called the “Queen of American Lakes” because of its exceptional clarity and scenic setting in the Adirondack Mountains. For generations, residents and visitors have prized its transparent waters, vibrant fisheries, and tourism economy. Yet in rece…

When crews encounter contaminated sediments during routine work, or when a concerned homeowner reports a suspicious odor or unusual discharge, the situation calls for immediate but steady action. Stormwater systems often collect materials from a wide range of sources, and although many sediments are…

Constructed wetlands are engineered systems that mimic the natural processes of a real wetland in order to treat stormwater, wastewater, or other polluted runoff. They are intentionally designed and built rather than formed through natural hydrology, but they function in much the same way. Water flo…

Wetlands are often described as the kidneys of the watershed because they filter, slow, and transform the water that passes through them in ways that protect downstream ecosystems. This comparison is more than a poetic metaphor. It captures the essential truth that wetlands perform quiet but powerfu…
