    The new mining corporations developed extraction techniques that were frighteningly efficient, techniques that destroyed the rivers and caused California's first environmental disasters. Massive derricks lifted rock and sandobliterating the formerly pristine rivers. The worst of the large scale mining techniques came in 1853 hydraulic mining.

    The advent of hydraulic mining was among the major improvements to placer mining methods. It was one that had profound effects on Californias environment, leaving lasting scars on the earth, debris in the canyons and rivers, and a complex network of canals and ditches that shifted water to mining areas remote from their sources.

Today, hydraulic gold mining is only rarely practiced on an industrial scale, but gold mines on Alaska sometimes use it. It survives mostly in artisanal form in remote, undeveloped and largely unregulated areas of the world.
