The state of California has over 1,000 dams, many built from the 1930s to the 1970s to reduce flooding and to
create hydroelectric power. A dramatic decrease in salmon and trout populations were noted in the dammed
rivers. The state has recently begun to research dam removal to restore rivers to their original flow. Which of
the following is a possible benefit of removing some dams?
restoration of migrating fish habitats and related food web species
increased hydroelectric power output from remaining California dams
© better long-term drought prevention from reservoirs
D a decrease in flooding events downstream from where the dam is removed
