| 説明 | The Puerco River in northwestern New Mexico and northeastern Arizona flows through arid terrain including the Painted Desert. The main tributary of the Little Colorado River, it drains an area of about 2,654 square miles (6,870 km2) and is 167 miles (269 km) long.[3] The river's average discharge is very low, less than 70 cubic feet per second (2.0 m3/s) in normal years, because its drainage basin is extremely dry. For most of the year, the river is a braided wash containing little or no water, although large flash floods can occur in downpours. Navajos in the Puerco River valley have used surface waters in the river for livestock watering for decades. From the 1950s to the early 1980s, the Puerco ran almost continuously with wastewater, some untreated, from uranium mines upstream.en.wikipedia.org/wiki/Puerco_Riveren.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
