Water Level

Every effort is made to keep the water level of Corps lakes within several feet of their conservation pool. During a drought, local municipalities (who own most of the water) have the right to use the water for their citizens. As a result, the lake level may be drawn down considerably during periods of high consumption and low rainfall.
