The sediment would be scooped up from the bottom, and then pumped over to the deposition sites, where a large sprayer, similar to a fire hose, would “rain” the sediment down upon the areas targeted. The agency has identified a few potential sites to place the deranged sediment, including Holt’s Landing, James Farm and the Delaware Seashore State Park. Mohan says the 30-50,000 cubic yards of sediment will help Delaware’s marshes be more resistant to sea level rise and continue to provide habitat and prevent flooding. “So this particular technology, thin layer placement, is merely accelerating the natural process of sediment deposition that happens in back bay systems due to the incoming and outgoing tides,” said Ram Mohan with Anchor QEA, a firm that works on projects like White Creek. “If a channel is perpetually filling in and becomes a navigation problem it will be at the top of our list repeatedly and may be subject to dredging again and again,” Hayden said.ĭNREC has also decided to use the material scooped from the riverbed to help raise up nearby marshes. Jesse Hayden from DNREC says because of a lack of state and federal funding, they can’t guarantee any waterway gets dredged on a regular basis. Now, the waterway is again clogged with underwater hazards and sandbars - making the creek difficult to use, even with the waterway markings in place.ĭNREC identified White Creek as one of its first dredging projects to start after getting feedback from boaters who use the state’s waterways. White Creek hasn’t undergone dredging since the early 2000’s. White Creek was listed as the highest priority for dredging in a recent survey of Delaware’s waterways.Īnd the process of making White Creek safer to navigate is underway.
