Newly discovered damage in Glen Canyon Dam would require releasing less water at low reservoir levels — a problem that increases water risks in the Southwest.
Members of the Local Environmental Action Demanded (LEAD) Agency, an area advocacy group, worry that raising the water level will make flooding worse at the lake's upstream rivers.
