In 2024, two conservation ditch projects were implemented on local Singer Farms’ property with funding from DRA.
The main objectives of these projects were to enhance water quality and create better wildlife habitat while forming a self-developing stream channel that will naturally evolve over time. These overwide ditch projects are designed to slow down water flow, minimize erosion, and boost nutrient retention, ultimately reducing sediment and pollutants entering nearby waterways. Each of these projects has the goal of slowing runoff from surrounding farm fields, yet they take different, tailored approaches to best suit their locations.
These projects are part of a larger initiative to reduce agricultural runoff and improve local water quality. Our research assistants will monitor the site continuously to track long-term effects on water quality, starting in 2025.
OVERWIDE DITCH:
Originally, this 1/2-mile-long ditch had a bottom width of approximately 3′ and a depth of 3′. Excavation work focused on reshaping the north bank while leaving the south bank and bottom intact. The new 5:1 slope is designed to facilitate future vegetation maintenance, which is essential for filtering excess nutrients such as nitrogen and phosphorus before they reach larger bodies of water. As erosion gradually shapes the channel, it will resemble a natural stream, providing a habitat for aquatic life. In spring 2025, native grasses like Switchgrass, Big Bluestem, and Indian Grass were planted, along with wildflowers, to promote biodiversity and support pollinators.
SELF-FORMING DITCH:
The self-forming ditch design acts similarly to a natural stream, allowing it to chart its own path within a more controlled footprint. This effect is achieved by widening the original ditch bottom and constructing sloped sides. This approach encourages the formation of meanders, pools, and berms that mimic the natural features of small waterways. Additionally, the planting of native species along the ditch banks will help filter pollutants and sustain wildlife over time. As these systems mature, they will become increasingly more effective and self-sustaining.
