dam
a barrier controlling the flow of water and backing up water. Forms a lacustrine habitat (the reservoir) for fish where one did not exist before. Initially fish production is very high when stocked but declines as nutrients from flooded terrestrial ecosystems are used up. Release of water from reservoirs may radically affect fish downstream by changes in temperature regimes, flushing of habitats, and changes in silt loads. Storage dams store water and diversion dams divert water
