Conservation pool is what is commonly known as "normal level"
Flood pool is the amount of water above conservation pool a lake can hold before going over spillway.
Medina is 70.7% of conservation pool. In this example, percent full is based on conservation storage and conservation capacity in acre feet of water. As the level increases, the area spreads out.
Dead pool is the level that no water can be withdrawn or released due to being below the gates.
