Rio Grande water levels and flow now

The Rio Grande is currently running at very low to seasonally low flows across most of its U.S. reach, with a few localized exceptions where releases or tributary inflows boost discharge. ^[1][2][3]

Current flow by key segment

Upper Rio Grande (Colorado → northern New Mexico)

• Gauges in the San Luis Valley and upper basin show very low to near‑zero flows at many sites (e.g., “0 cfs” above US‑380 near San Antonio, NM; single‑digit to low‑double‑digit cfs at several Albuquerque‑area gauges). ^[2]
• Some mid‑reach gauges below dams (e.g., below Cochiti Dam) are running in the low hundreds of cfs (around 200 cfs), classified as “very low.” ^[2]

Central New Mexico (Elephant Butte reach)

• The strongest single flow reported on the mainstem is below Elephant Butte Dam, at about 2,080 cfs, flagged as “high” relative to other Rio Grande gauges. ^[2]
• At Elephant Butte Lake itself, the lake stage is reported around 4,275 ft, with downstream Caballo Lake near 4,134 ft. ^[1]
• Downstream of these reservoirs, flows drop sharply again (tens to low hundreds of cfs) at many gauges. ^[2]

El Paso / southern New Mexico – west Texas

• Near El Paso, the river is extremely low: roughly 8.4 cfs with a stage around 1.65 ft and warm water (~87 °F). ^[1][3]
• This matches the broader pattern of minimal natural flow in the desert reach, heavily dependent on diversions and occasional releases. ^[2][3]

Lower Rio Grande (Falcon Lake to the Gulf)

• At Falcon Lake, a very large release is showing: about 26,900 cfs with a stage near 263 ft, indicating a major operational pulse or flood‑control release. ^[4]
• Farther downstream toward the coast, older daily reports (from 2025) show the river at Brownsville with only a few cfs, but those are not “now”; the Falcon Lake pulse suggests significantly higher flows in the lower valley when that release propagates. ^[5][4]

How “now” these data are

• Most of the real‑time gauge pages (NOAA/USGS via RiverApp, How’s Your River, StreamflowData) are dated within the last few days of late August 2026 and are intended as near‑real‑time. ^{[1][2][4][3][6]}
• The International Boundary and Water Commission (IBWC) daily flow table you’ll see on some sites is often updated only on weekdays and may lag by a day or more; treat those as recent but not instantaneous. ^[5]

Where to check live yourself

For the most up‑to‑the‑minute numbers at a specific location:

• USGS Water Data (National Water Dashboard) – search “Rio Grande” and pick your gauge for current discharge (cfs) and stage.
• NOAA National Water Prediction Service – e.g., “Rio Grande at Laredo” or “Rio Grande at Columbia Bridge” for stage and flood status. ^[7][8]
• RiverApp / How’s Your River – user‑friendly views of the same USGS/NOAA feeds, with simple graphs and temperature. ^[1][4][3][6]
