The current limit of offshore control by the State of Texas is defined as 3 marine leagues. A marine league is a measurement of approximately 3.452 miles, which establishes the jurisdictional boundary for the state over navigable waters beyond the coastline. This limit stems from Texas's historical land grants and legal precedents, which grant the state authority and rights to resources and governance up to this specified distance from the shore.

This jurisdiction includes the management of natural resources, regulatory powers, and environmental oversight in this maritime zone. The establishment of this boundary reflects the unique legal status of Texas, derived from its annexation into the United States and its original land grants when it was an independent republic. Being aware of the 3 marine leagues limit is crucial for surveyors and professionals in the field as it affects land use, resource management, and property rights along the Texas coast.
