Summary Slope movements induced by reservoirs involve various types of movement and geologic materials. Because they may be large and very rapid, rock slides related to reservoirs generally have been considerably more destructive than slope movements in surficial materials. The Grand Coulee Dam impoundment, Franklin D. Roosevelt Lake on the Columbia River in the United States, has been the site of hundreds of reservoir-induced landslides since filling of the reservoir in the early 1940's. These slides occurred, and are still occurring, in unconsolidated Pleistocene glaciofluvial materials which constitute much of the rim of the reservoir. Another interesting case study on the Columbia River is provided by the Downie Slide in Canada. This 1500 million $ m^{3} $ prehistoric rock slide is of considerable importance because it will be situated on the bank of a major reservoir that is still in the planning and construction stage. In the United States, impetus has been given to dam safety programs by the recent failures of Teton and Toccoa Dams. Although these failures did not result from landslides of the reservoir rims, the increased awareness of the importance of dam safety has also spurred national interest in landslides that constitute hazards to reservoirs and dams.
