What alternatives do we lose by building dams? ● LED powered solar or wind energy, geothermal and pumped hydro “ Andrew Weaver” (Clark, 2017) ○ Costs have dropped can compete on cost-per-electron basis with hydropower “ Andrew Weaver” (Clark, 2017) ● Location determines viability of these different technologies (Rudd, 2016)

The impact of each dam is unique and depends not only on the dam structure but also on the attributes of local biota and climactic and geomorphologic conditions

● In riverine ecosystems molluscs can exceed the biomass of all other benthic organisms but require a narrow range of habitat conditions (Layzer et al., 1993) ● Changes in habitat reduce success of molluscs and allow for the inhabitation of non-native species (McCartny, 2009)

● ● ● ●

● Riparian corridors for birds and terrestrial animals are very important ( Decamps et al., 1987) ● Inundation of terrestrial ecosystems by reservoir results in the loss of habitat for birds and mammals and can lead to species extinction (Decamps et al., 1987) ● In arid regions reservoirs provide a permanent water resource that may benefit many species (Cowan & van Riet, 1998) A 1994 NASA satellite image shows Elephant Butte Reservoir at 89 percent capacity
