When the dam was built there was no attempt to clear the shores of the lake of standing timber, resulting in an unsightly band of dead trees when the waters rose. This vista, and the mudflats created by drawdown of lake waters, were cited in later years in successful arguments against reservoirs in

Jackson Lake Dam was a log-crib dam constructed in 1906–07 across the outlet of Jackson Lake, a natural lake. That dam raised the lake level by 22 feet (6.7 m), but the dam failed in 1910. A new concrete and earthen dam was constructed in stages between 1911

of 1983 in Idaho, the dam was upgraded during 1986–1989, and the Bureau of
Reclamation believed it could withstand the "maximum credible earthquake," a magnitude 7.5 quake on the Teton fault. Since then various studies have cast doubt on this belief.
