Environmental Benefits of Dredging. Dredging allows businesses to work with waterways to create better and healthier aquatic ecosystems. One of the largest benefits of dredging waterways is helping to reduce eutrophication, which is an excessive amount of nutrients in a water body typically caused by water runoff from the surrounding land.
The new ability to work the bottoms of rivers led to the quick expansion of suction dredging throughout the State of California and western rivers. In the 1950's suction dredging was completely unregulated. Regulation began in 1961 when the California legislature passed SB1549 which was focused on the effects of suction dredging on salmon.
In 1932 the Bulolo Gold Dredging Co. made a successful Bendilari jig (a diaphragm jig) installation aboard a dredge in New Guinea where jigs handled the total output of the dredge. Placer Development Ltd. engineers designed a new jig patented it in 1936, and made an arrangement with Pan-American Engineering Corp. for manufacturing rights.
