ALBUQUERQUE, N.M. (AP) Tumbleweeds drift along the Rio Grande as sand bars within its banks grow wider. Smoke from distant wildfires and dust kicked up by intense spring winds fill the valley, exacerbating the feeling of distress that is beginning to weigh on residents.

One of North Americas longest rivers, the Rio Grande is another example of a waterway in the western U.S. thats tapped out.

From the Pacific Northwest to the Colorado River Basin, irrigation districts already are warning farmers to expect less this year despite growing demands fueled by ever-drying conditions. Climate experts say March marked the third straight month of below-average precipitation across the U.S. and areas of record dryness are expanding in the West.
