Headline: Court confirms commissioners’ report and establishes the Texas–Oklahoma boundary along the Red River from the 100th meridian to eastern Lamar County, while allowing natural erosion and accretion to adjust the line.
Holding: The Court confirmed the commissioners' 1925 report and declared the mapped line the official Texas–Oklahoma boundary from the 100th meridian to eastern Lamar County, subject to natural erosion and accretion.
- Establishes official Texas–Oklahoma boundary along specified Red River stretch.
- Gives landowners, local officials and mapmakers an authoritative line for property and governance.
- Allows boundary shifts from natural erosion and accretion over time.
Summary
Background
A group of commissioners was appointed to run, locate, and mark parts of the boundary between Texas and Oklahoma along the south bank of the Red River. The commissioners filed a third report on November 16, 1925, showing the line they marked from the One Hundredth meridian of longitude to the eastern limit of Lamar County. This report did not cover the Big Bend and Fort Augur areas because those were handled in earlier reports that had already been presented and confirmed. No timely objections or exceptions to the third report were filed in the case.
Reasoning
The Court reviewed the third report and found no objections that would prevent confirmation. It adjudged, ordered, and decreed that the report be confirmed in all respects. The line shown in the report and on the attached maps was declared the true boundary between Texas and Oklahoma at the specific places described in the report. The Court also made clear the boundary remains subject to any future changes caused by natural, gradual erosion and accretion as set out in an earlier decree dated March 12, 1923. The clerk was ordered to send authenticated copies of this decree, the report, and the maps to the governors of both states.
Real world impact
This decree fixes the official river boundary for the identified stretch of the Red River, giving state officials, landowners, and mapmakers an authoritative line to use for property, governance, and administration. The decision preserves the rule that ordinary natural changes to the riverbank can move the boundary over time. The confirmed maps and report will be delivered to state governors for official use.
