1

Addicks Reservoir is a flood control lake. It is not used for water supply and under normal conditions it is empty.

2

Lake Amistad and Lake Falcon straddle the border of Texas and Mexico. By treaty, Texas has rights to 56.2% of the total conservation capacity of Amistad and 58.6% of the total conservation capacity of Falcon. The fraction of the actual storage that belongs to Texas is formally determined biweekly by the International Boundary Water Commission (IBWC). The IBWC is the legal repository of data related to this lake for treaty purposes and official versions of the datasets should be obtained directly from them. Conservation capacity is based on the fixed percent of total conservation capacity. Conservation storage is based on the bi-weekly changing Texas share.
