Research notes

Six designated scenic-river reaches: Illinois River (Cherokee/Adair/Delaware Cos.), Flint Creek (Delaware/Adair), Barren Fork Creek (Adair/Cherokee), Upper Mountain Fork above the 600-ft contour of Broken Bow Reservoir (McCurtain/LeFlore), Big Lee's Creek above 420 ft MSL (Sequoyah), and the Lower Illinois (segment below Tenkiller). **Oklahoma has no National Wild & Scenic Rivers Act mileage** — federal conflict check is theoretical absent future designation. Polygon source: GRDA publishes static PDF/maps (e.g., Illinois River Guide 2025); not yet available as a REST endpoint — flag as a data gap. After 2016, GRDA absorbed the former Oklahoma Scenic Rivers Commission.
