Relying on Hughes v. Washington, 389 U.S. 290 (1967) and Bonelli Cattle Co. v. Arizona, 414 U.S. 313, 4 ELR 20094 (1973), the trial court rejected the notion that boundary lines may be fixed by a state at the date of its entry into the Union and held that federal law must govern, including the requirement that riparian owners were entitled to natural and artificial accretions.
