Commuters driving along Loop 820 over Lake Worth have been noticing large barges in the site of the setting sun. These flat-bottomed boats house the equipment used to pump millions of cubic yards of silt quietly through pipes to a compost site about 1.7 miles away. The sand-and-water mixture is being sent through a 20-inch pipe to the privately-owned Silver Creek Materials west of Loop 820. Silver Creek is using the silt to make compost. The dredging is designed to improve the lake’s safety, water quantity and recreational allure. The first phase is expected to be completed this year.
