Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality.

Small-scale, family-owned gold mining has been active on the Fortymile since the "gold rush" days of the late 1880's. However, in 1980, the Fortymile River and many of its tributaries received Wild and Scenic River status. Because of this status, mining along the river must compete with recreational usage such as rafting, canoeing, and fishing.
The environmental impact of mining can occur at local, regional, and global scales through direct and indirect processes, leading to erosion, sinkholes, biodiversity loss, and the contamination of soil, groundwater, and surface water by chemicals from mining processes.
Small-scale gold mining isn't really that small in reality. Workers employ a variety of methods and mining techniques. They pan for gold, dredge rivers, manually dig up ground with shovels, work with hydraulic systems, use mechanized crushers, and often utilize large earth moving equipment.
