Grassed Waterways and Buffer Strips

Grassed waterways are designed to convey runoff water from fields to a stable outlet in a non-erosive manner.

Grassed waterways are typically constructed with a slope of 1-2% to ensure that water flows smoothly and does not cause erosion.

A mixture of grasses and legumes is typically used in grassed waterways to provide year-round cover and help stabilize the soil.

Grassed waterways are typically constructed with a width of 30-40 feet to accommodate the volume of runoff water and prevent erosion.

Buffer strips serve multiple purposes, including reducing soil erosion, improving water quality, and providing wildlife habitat.

Buffer strips are typically constructed with a width of 20-30 feet to provide adequate protection from erosion and water pollution.

Buffer strips can include a variety of vegetation, including native grasses, wildflowers, shrubs, and trees, to provide multiple layers of protection.

Grassed waterways and buffer strips contribute to soil conservation by reducing soil erosion, improving water infiltration, and increasing soil organic matter.

Grassed waterways and buffer strips provide multiple benefits for water quality by reducing sediment and nutrient runoff, filtering pollutants from runoff water, and helping to stabilize stream banks.

Grassed waterways and buffer strips provide multiple benefits for wildlife by providing habitat, food, cover, and wildlife corridors.

Installing and maintaining grassed waterways and buffer strips can be challenging due to cost, land requirements, and maintenance requirements.

Proper site selection, proper design and construction, and regular maintenance are all important best management practices for installing and maintaining grassed waterways and buffer strips.

There are several government programs that provide financial assistance for installing grassed waterways and buffer strips, including the Conservation Reserve Program (CRP), Environmental Quality Incentives Program (EQIP), and Agricultural Management Assistance Program (AMA).

Farmers and landowners can work with local conservation districts to install and maintain grassed waterways and buffer strips by contacting their local conservation district, attending conservation district meetings, and participating in conservation district programs.

Installing grassed waterways and buffer strips can provide long-term benefits, including reduced soil erosion, improved water quality, and increased wildlife habitat.
