Excerpt: 457 U.S. 172 102 S.Ct. 2923 72 L.Ed.2d 762 State of TEXAS, plaintiff,v.State of OKLAHOMA No. 85 Supreme Court of the United States June 14, 1982 1 On bill of complaint. DECREE 2 The motion for entry of judgment by consent of plaintiff and defendant, with the deletion of paragraph 10 thereof, and as amended with respect to paragraph 7, is granted. IT IS ORDERED, ADJUDGED, AND DECREED: 3 1. This judgment determines the boundary line between Texas and Oklahoma along the South bank of the Red River in Grayson County, Texas, from a point on said River as it existed prior to the construction of the Texoma Reservoir Dam (Denison Dam) approximately 1973 feet West of the center line of said Dam, with its meanders, to a point on said River approximately 6103 feet East of the center line of said Dam, upon the Complaint, Answer and agreement of Counsel for Texas and Oklahoma. 4 2. The source of the boundary line between Texas and Oklahoma from the 100th meridian of longitude to the eastern border of Oklahoma (which encompasses the boundary determined by this judgment) lies in the Treaty of 1819, 8 Stat. 252 (1821), which was construed by the Court in United States v. Texas, 162 U.S. 1, 16 S.Ct. 725, 40 L.Ed. 867 (1895), to be the south bank of the Red River. The Court later confirmed this definition of the boundary in Oklahoma v. Texas, 256 U.S. 70, 41 S.Ct. 420, 65 L.Ed. 831 (1921), and in a later partial decree therein, 261 U.S. 340, 341-342, 43 S.Ct. 376, 377, 67 L.Ed. 687 (1923), defined the South bank as: 5 ". . . the water-washed and relatively permanent elevation or acclivity, commonly called a cut bank, along the southerly side of the river, which separates its bed from the adjacent upland, whether valley or hill, and usually serves to confine the waters within the bed, and to preserve the course of the river. 6 ". . . The boundary between the two states is on and along that bank at the mean level attained by the waters of the river when they reach and wash the bank without overflowing it. 7 ". . . At exceptional places where there is no well-defined cut bank, but only a gradual incline from the sand bed of the river to the upland, the boundary is a line over such incline, conforming to the mean level of the waters, when at other places in that vicinity they reach and wash the cut bank without overflowing it." 8 3. As a result of the partial decree in 1923 and other partial decrees arising from the same controversy, a boundary commission was established to take evidence, find facts and report to the Court. Said Commission filed a documentary report, 269 U.S. 536, 46 S.Ct. 104, 70 L.Ed. 399 (1925), styled as the Third Report of the Boundary Commissioners. At page 41 of said Report appears the following entry: VII. 9 "IN GRAYSON COUNTY, TEXAS OPPOSIVE 10 MARSHALL AND BRYAN COUNTIES, 11 OKLAHOMA. 12 "Public Hearing: Sherman, Texas, May 7, 1925 13 "We found no avulsive changes in the position of the Red River in this County and make no surveys." 14 4. In 1939 the United States Army Corps of Engineers made surveys of certain tracts of land in Grayson County, Texas, known as Tract T-2-1, Tract T-2-2 and Tract T-2-4, whose northern boundaries coincide with the South bank of the Red River and the boundary determined by this judgment. Said surveys were made in anticipation of the condemnation of said Tracts for purposes of the construction of the Texoma Dam Facility and Reservoir pursuant to an Act of Congress, 52 Stat. 1215 (1938). 15 5. On September 7, 1940, a judgment was entered in the United States District Court for the Eastern District of Texas making final the award of special commissioners as to Tract T-2-1. On November 23, 1940, judgment was entered in the United States District Court for the Eastern District of Texas making final the acquisition by the United States of Tract T-2-4. On December 28, 1939, a warranty deed was executed by P. O. Brack to the United States as to Tract T-2-2. 16 6. On June 23, 1980, the Plaintiff and Defendant together retained a Registered Public Surveyor of the State of Texas to make a reenactment survey of Tract T-2-1, Tract T-2-2 and Tract T-2-4. On the basis of such survey it has been determined that, when tying back to the original South bank of the Red River, the northern boundaries of Tracts T-2-1, T-2-2 and T-2-4 (coinciding with the South bank of the Red River) as established by the U. S. Army Corps of Engineers in its survey of 1939 were correct at the time that survey was made, which was prior to the construction of the Texoma Reservoir Dam Facility. A certified copy of the plat of the survey commissioned by the States with the surveyor's certified explanation thereof is filed with the Clerk of this Court. 17 7. The boundary between Texas and Oklahoma determined by this judgment coincides with the boundaries of Tracts T-2-1, T-2-2 and T-2-4 and is described as follows, with all bearings from the above referenced judgment and deed descriptions, and all distances in feet: 18 BEGINNING at a point, same being the centerline of Shawnee Creek and the Northeast corner of Tract T-2-4 as acquired by the United States in a Judgment as recorded in Volume 420 Page 556 of the Deed Records of Grayson County, Texas. 19 THENCE up the south bank of the Red River as it existed prior to the construction of the Texoma Reservoir and Denison Dam, with its meanders: South 78x08' West a distance of 528.9 feet; South 86x10' West a distance of 1370.50 feet; South 89x06' West a distance of 484.0 feet; North 88x22' West a distance of 447.2 feet; North 85x37' West passing the Northeast corner of Tract T-2-2 as recorded in Volume 417 Page 23 of the Deed Records of Grayson County, Texas and the total distance of 1675.30 feet; North 76x21' West a distance of 413.7 feet; North 86x01' West a distance of 170.10 feet to the Northwest corner of Tract T-2-2; 20 THENCE North 76x01' West a distance of 394.50 feet; North 87x34' West a distance of 1198.90 feet; North 68x27' West a distance of 362.20 feet; North 55x54' West a distance of 1030.80 feet to a point, same being the Northwest corner of Tract T-2-1 as acquired by the United States in a Judgment as recorded in Volume 417 Page 123 of the Deed Records of Grayson County, Texas. 21 8. The boundary line delineated hereinabove is depicted by a line marked "STATE LINE" on the plat of the survey commissioned by the States and filed with the Clerk of this Court. 22 9. The construction of the Texoma Reservoir and Denison Dam did not alter the boundary between Texas and Oklahoma as the South bank of the Red River as it existed prior to such construction in any manner whatsoever. 23 10. The cost of this action shall be equally divided between the two States.
