Several studies have documented the bed degradation caused by the two general forms of instream mining: (1) pit excavation and (2) bar skimming.

June 2019 Gravel and Rock Mining and Sand Cliffs

That application included 50,000 cubic yards instream mining per year, and an asphalt batching plant. The proposal violated the National Marine Fisheries Service's National Gravel Extraction Policy, which describes the effects of riverine gravel removal and its impacts on salmonids. Its scientific conclusions have stood the test of time.

Sand mining and its impact IAS Score

The sand is dug up, the valuable minerals are separated in water by using their different density, and the remaining ordinary sand is re-deposited.
