Hydraulic Dredging is definitely one of the best options.
Making your way through canals or lakes is something many boat owners are familiar with. Material builds up at the bottom of the canal and lakes which caused lower canal levels and ruins the water quality and usability.
Hydraulic dredging of canals will weed out unneeded slug and overgrowth. A properly hydraulically dredged, clean canal gives ideal conditions for important aquatic plants to thrive.
