Lake Falcon straddles the border of Texas and Mexico. By treaty, Texas has rights 58.6% of the total conservation capacity. 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 58.6% of total conservation capacity. Conservation storage is based on the bi-weekly changing Texas share.
