Dams provide us with a source of clean energy. Water in a reservoir often has a different temperature and oxygen level than water in a free-flowing river, and water released from a reservoir can adversely affect water quality downstream, potentially impacting native fish and vegetation. Solutions to major challenges are rarely simple, especially in a world rife with the difficult issues that we face today. But over the years, as land was acquired for the reservoir project, residents moved away and buildings were demolished. This mixes air into the water, helping increase dissolved oxygen levels.In at least some places, the water in a lake is too deep for plants to. The program includes a new dam, named after a longtime mayor of Ladonia, Leon Hurse, who was an early visionary for the lake project, Motley notes.
