Silt is suctioned out of the lake and pumped up to dumpsters that are hauled away. Dredging is conducted with a barge mounted industrial pump that sucks the silt off of the lake bottom and then sends it through a discharge hose to a nearby dumpster. The water drains out of the dumpster and the silt remains which is then hauled away to the dump. This method of dredging is in compliance with all City of Austin guidelines and is more cost effective than other methods of dredging that require the silt to be handled more than once.
