Areas of concentrated water flow within fields can result in the formation of ephemeral or classic gullies - ruts cut by water channels that can become deeper and wider over time if not treated. Gully erosion is a primary source of sediment delivery to our streams and waterways, resulting in increased turbidity. Turbidity is a measure of the cloudiness or haziness of water resulting from an increase in suspended solids. Greater turbidity is a threat to water quality and wildlife habitat.
Grassed waterways eliminate gully erosion in susceptible areas by channeling concentrated flow into strips of perennial grasses that slow water flow and trap suspended sediment and nutrients.
