CIBOLA COUNTY, N.M. – As May comes to a close, water conditions across Cibola County continue to reflect a warm and persistently dry spring.
Bluewater Lake declined again over the past week, the Rio San Jose remained steady, and precipitation data shows much of the county saw little to no measurable moisture during the reporting period. According to U.S. Geological Survey and Drought.gov data, the broader trend remains one of slow drying heading into the early summer and fire season months.
Bluewater Lake
Bluewater Lake measured 7,366.57 feet in elevation on May 26, according to provisional data from the U.S. Geological Survey. That is down from 7,366.72 feet recorded May 19, continuing the gradual seasonal decline that has persisted throughout spring.
The continued drop reflects limited inflow following a weak snowpack season and several weeks of minimal precipitation.
Rio San Jose
The Rio San Jose at Acoma Pueblo measured 1.92 feet on May 26, unchanged from the previous week according to provisional USGS data.
The river has now held at this level through multiple reporting periods, indicating stable but modest base flow conditions with little evidence of significant watershed recharge.
Precipitation in Cibola
Temperature and precipitation data from Drought.gov provides additional context to understand the county’s drying.
The seven-day departure from normal maximum temperature map, valid May 19, showed much of the Grants and El Malpais area running warmer than average, generally between one and three degrees above normal. Some areas farther east and southeast showed even warmer anomalies. While these numbers may not appear dramatic on their own, warmer-than-normal conditions increase evaporation and accelerate drying in soils, grasses, and other vegetation.
The seven-day precipitation map, valid May 19, showed much of the county receiving little to no measurable moisture during the week. Most of the Grants and El Malpais area appeared nearly blank on the map, indicating conditions ranging from essentially dry to only trace precipitation. A few isolated areas showed very light moisture, but no widespread rainfall event developed.
Longer-term patterns continue to reinforce the dry spring trend.
The 30-day departure from normal maximum temperature map showed much of the region leaning slightly warmer than average overall during the past month. At the same time, the 30-day percent of normal precipitation map continued to show much of the Grants and El Malpais area below normal for moisture, generally ranging from 50 to 75 percent of average precipitation, with some areas even lower.
This week’s data shows Cibola County is continuing to move through a warm and dry late-spring pattern. Bluewater Lake continues its gradual decline, the Rio San Jose remains steady, and precipitation has not been sufficient to offset drying conditions. As June approaches, concerns surrounding drought, vegetation stress, and wildfire conditions are likely to remain elevated across western New Mexico.
