Because water is always moving and naturally carrying materials that settle and need to be dredged, maintenance dredging is a constant, cyclical process of upkeep. Maintenance dredging is predominantly used as a means of maintaining required depths for boats and ships to safely traverse navigation channels. A smaller, offline lake could not be constructed using lake sediments, would require large quantities of suitable material to be trucked in through neighborhoods, and, although feasible, poses potentially significant risk for long term safety and maintenance.What is the purpose of maintenance dredging?.Lake Accotink would need to be dredged again every five years in order to keep up with the sediment accumulation, requiring a year of work and 15,000 truck trips for each recurring dredge.Costs to complete the dredging work have gone up dramatically since the pandemic began.Free disposal of dredged spoils options are not available today as they were for previous dredge events. ![]() Hauling of the increased sediment amount would require 50,000 truck trips through neighborhood and area roads.Southern Drive: would require heavy truck access through residential neighborhoods. ![]() Wakefield Park Maintenance Facility: would require clearing seven acres of forested wetlands and upland forest to process spoils. ![]()
