I grew up on Texoma fishing and boating. All the above are correct. Be cautious of wind forecasts (direction and speed) with regards to getting back to the ramp. Give a safe distance on the Oklahoma side of islands, they are all sand, which means what was navigable a couple of years ago may not be now. If running the Big Mineral area there are a couple of submerged islands at the mouth, stay to the east going in. Several of the sandbars on the west end and east/north of the islands shift around when it floods, not drastically usually, but enough that the gps might not have the most accurate info.
