Cibola Water Monitoring Report – July 7–14

Body

CIBOLA COUNTY, N.M. – A week after forecasts began hinting at a more active monsoon pattern, the latest water monitoring data shows Cibola County continuing to wait for meaningful relief from drought.

Bluewater Lake continued its gradual decline during the week, while the Rio San Jose posted a slight increase.

Although little rain fell over the county during the past seven days, the latest National Weather Service forecast now points to the potential for significantly more widespread precipitation during the coming week. At the same time, Bluewater Lake has been placed under a Harmful Algal Bloom (HAB) Watch, reminding visitors to check current water conditions before heading to the lake.

Bluewater Lake

According to provisional U.S. Geological Survey data, Bluewater Lake measured 7,365.23 feet in elevation on July 14, down from 7,365.39 feet one week earlier.

The gradual decline continues a trend that has persisted throughout much of 2026 as drought and limited runoff have reduced water levels.

Adding to this week's developments, the New Mexico Environment Department announced the launch of its new online Harmful Algal Bloom Advisory Map, which provides current algae bloom conditions at monitored lakes across the state.

Bluewater Lake is currently listed under a HAB Watch Advisory, meaning there is evidence a harmful algal bloom may be developing.

According to NMED, visitors should avoid getting untreated lake water in their mouths, avoid swimming near visible algae, keep pets away from algae along the shoreline, and rinse fish with clean water before cooking, eating only the fillets. The department recommends checking the advisory map before visiting New Mexico lakes throughout the summer and fall monitoring season. Rio San Jose

The Rio San Jose at Acoma Pueblo measured 1.89 feet on July 14, according to provisional USGS data, up slightly from 1.88 feet the previous week.

While the increase is small, the river has remained relatively stable throughout the year despite worsening drought conditions across Cibola County.

Precipitation across Cibola

The latest maps from Drought.gov show another hot week across western New Mexico.

The seven-day average maximum temperature map indicates most of Cibola County experienced average daytime highs in the 80s to low 90s, continuing the pattern of above-average warmth that accelerates evaporation and dries vegetation.

Despite those temperatures, observed precipitation during the previous week remained limited. The sevenday precipitation map shows most of the county received only trace amounts to around one-half inch of rain, with many locations receiving considerably less.

The outlook for the week ahead is considerably more encouraging.

According to the National Weather Service Weather Prediction Center's seven-day quantitative precipitation forecast, much of Cibola County could receive between one-half inch and 1.5 inches of precipitation, with some localized areas potentially seeing even higher totals if thunderstorms repeatedly develop over the same locations. While forecast rainfall amounts can change and thunderstorms are inherently variable, the outlook represents one of the wettest precipitation forecasts the county has seen this year.

Even with that improving forecast, drought conditions remain severe.

The latest U.S. Drought Monitor, valid July 7, shows 95.37 percent of Cibola County remains in Extreme Drought (D3), while the remaining 4.63 percent is classified as Severe Drought (D2). All of Cibola County remains in drought.
