 Between initial dredging in August 2016 and project completion in August 2018, workers dredged over 50,000 tons (33,000 cubic yards) of sediment and soil, stabilized riverbanks to prevent future contamination and erosion, and disposed of contaminated materials at an approved landfill.A temporary water control structure that was built in 2015 to replace the dam was removed, and the river is now an open channel.The area around the former auxiliary spillway has been restored as a wetland area.
