New Mexico Basin Outlook Report for 
RIO GRANDE BASIN as of February 1, 2013

Streamflow forecasts for the Rio Grande Basin range from 35 percent of normal for the Jemez River below Jemez Canyon Dam, to 70 percent of normal for the Rio Lucero near Arroyo Seco. The Rio Grande at Otowi Bridge is forecast to be 53 percent of normal or 380,000 acre- feet, while The Rio Grande at San Marcial is forecast at 39 percent or 197,000 acre-feet. Precipitation for January was below normal at 79 percent, up slightly from January last year. Year-to-date precipitation is only 65 percent of normal, compared to last year’s 101 percent at this time. Snowpack in the basin is 75 percent of normal, down somewhat from last year’s 85 percent at this time. Total reservoir storage in the basin is less than 585,000 acre-feet, continuing to drop from last year’s 896,700 acre-feet. This is only 29 percent of the 30 year average of 2,008,900 acre-feet. There was no report for Costilla Reservoir this month due to equipment issues, but storage last month was only 2,300 acre-feet. Abiquiu is the only reservoir in the basin to post above average storage for January at 105 percent, but even this is down somewhat from last year. Elephant Butte storage continues to fall this year, with storage of 183,100 acre-feet as opposed to 333,300 acre-feet at this time last year. This is roughly 14 percent of the 30 year average of 1,299,000 acre- feet for Elephant Butte. Water users in Rio Grande Basin should plan for reduced water supply this year with the limited storage currently held in upstream reservoirs.
