In 2000, dredging and other sand mining become so intensive along the Yangtze River that Chinese authorities banned the activity along the lower and middle reaches of the river. This drove many sand mining operators to Poyang Lake, a large body of water that flows into the Yangtze about 600 kilometers (400 miles) upstream of Shanghai.
While no international conventions regulate the extraction, use and trade of landbased sand (sand quarry, riverine and lake aggregate), the United Nation Convention on the Law of the Sea, 1982 (UNCLOS) provides for the delimitation of maritime zones and regulates rights and obligations in respect of usage, development and preservation for these zones, including resource mining.

Different mining methods (mechanical or manual) are adopted for the extraction of sand from these sources under dry (above water table) and/or wet (below water table) conditions. This chapter describes briefly the different sources, methods and hydrogeological bearings of sand and gravel extraction processes in river ecosystems.
Syncrude began mining oil sands from Mildred Lake in 1978. Syncrude''s mining operation was very similar to Suncor''s, initially using draglines and bucketwheels to shovel the ore onto conveyors that transported the oil sands to the processing plant.
