Reservoirs may cover important natural areas, agricultural land, or archeological sites. Groundwater depletion, a term often defined as long-term water-level declines caused by sustained groundwater pumping, is a key issue associated with groundwater use. This limits their ability to access spawning habitat, seek out food resources, and escape predation. Water used for cooling is warmer than the river itself, and this is also a form of pollution. By far the largest mining endeavor globally is digging up sand, mainly for the concrete that goes into buildings. The restoration effect was quantified by comparing each of the 20 restored river sections to a nearby non-restored, i.e. Constructed in 1941, the dam was built to harness the immense power of the Columbia River and turn this into electrical power supply.

The negative effects of erosion on yields and the production potential of land vary widely (from nil to heavy). Habitats both within and alongside rivers are particularly rich, often supporting a high diversity of species. However, the cost of off-site damage in terms of eroded fields is generally much higher, and the effects much more spectacular, amply justifying the majority of large-scale erosion control schemes.
