Green Peter Dam is a concrete gravity dam impounding the Middle Santiam River in Linn County in the U.S. state of Oregon. It was completed in 1967 to generate hydroelectricity, prevent flood damage, provide irrigation, and improve water quality downstream. It has been leaking for many years but is considered to be safe by authorities. Water released by the dam is regulated by the Foster Dam 7 miles (11 km) down the river.
