Drainage areas of the Twelvepole Creek basin, West Virginia; Big Sandy River basin, West Virginia; Tug Fork basin, Virginia, Kentucky, West Virginia

Drainage areas were determined for 61 basins in the Twelvepole Creek basin, West Virginia; 11 basins of the Big Sandy River Basin, West Virginia; and 210 basins in the Tug Fork basin of Virginia, Kentucky, and West Virginia. Most basins with areas greater than 5 square miles were included. Drainage areas were measured with electronic digitizing equipment, and supplementary measurements were made with a hand planimeter. Stream mileages were determined by measuring, with a graduated plastic strip, distances from the mouth of each stream to the measuring point on that stream. Mileages were reported to the nearest one-hundredth of a mile in all cases. The latitude and longitude of each measuring point was determined with electronic digitizing equipment and is reported to the nearest second. The information is listed in tabular form in downstream order. Measuring points for the basins are located in the tables by intersecting tributaries, by counties, by map quadrangles, or by latitude and longitude. (Woodard-USGS)
