About Pecos River below Avalon Dam
The Pecos River below Avalon Dam sits in the Upper Pecos-Black watershed in New Mexico.
The watershed
The gauge drains 18,080 sq mi (46,827 km2) upstream of this station. That is the area feeding the river at this point, not the full watershed on a map.
For people watching this reach, the record range matters more than the label. The highest level in the record is 9.94 ft (3.03 m) in September 2014, and the lowest is 2.71 ft (0.83 m) in July 2008. That spread tells you how much the river can change from one season or event to another.
The usual seasonal pattern is tight: the highest typical month is November at 2.85 ft (0.87 m), and the lowest typical month is August at 2.82 ft (0.86 m). The typical annual swing is 0.4 in (1 cm). For a dock, intake, or fishing access point, that means the water level usually stays close to its seasonal band, even though the long record shows larger extremes.
What the numbers say
With 50 years on record, this station gives a long view of the river at a fixed point. In the USGS record, that is enough time to see both the rare highs and the ordinary month-to-month range.
For this part of New Mexico, the seasonal pattern is not a big spring surge in the gauge record. The monthly typical levels stay nearly flat, and late summer is slightly lower than late fall. That is the pattern to watch when planning access, bank work, or water use nearby.
The record high in September 2014 and the record low in July 2008 set the outer bounds of what this reach has shown at the station. The gap between them is the difference between an unusual high-water period and a low stage that can affect shallow access.
Reading the hero number
The hero number on this page is today’s reading, compared with the median for this calendar day across the station record. That is more useful than raw elevation because it tells you whether today sits high or low for the date, not just what the staff gage reads.
At this USGS station, the comparison is anchored in more than 50 years of record. That context helps cottagers, anglers, and water users judge whether today is ordinary for the day of year, or outside the usual range.
How this page is built
Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
How Nibi Metrics works · Water stories
Nibi Metrics - live water levels, flow, and forecasts for 17,900+ lakes and rivers
Real-time water levels, forecasts, and alerts for lakes and rivers in a growing number of countries. Built on official government data.
Nibi Metrics tracks more than 17,900 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's water monitoring network, and on the Great Lakes the Canadian Hydrographic Service and NOAA. Every number on the platform is measured, not modelled - taken from a government gauge on the water itself and compared against that location's own historical record for this exact date.
What you can see for any monitored lake or river
The level right now, in feet or metres, updated as the source agency publishes new readings - for many stations that is every five to fifteen minutes. How today compares to typical: every location carries its own typical-for-this-date band built from its historical record, so a reading is never just a number - it is above, below, or near what this water usually does on this calendar day. Which way it is moving: a measured RISING, FALLING, or STEADY verdict computed from the gauge's own recent readings, with the rate of change - the difference between a flood ending and one beginning. What comes next: level forecasts up to 72 hours ahead, driven by the gauge's recent behaviour, upstream water, and quantitative precipitation forecasts, alongside live radar, lightning, and weather for the surrounding region.
Alerts that watch the water for you
Set a threshold on any location - a level, a distance above typical, or a rate of climb - and Nibi emails or notifies you the moment the gauge crosses it. Cottagers use it for spring freshet, anglers for river conditions, marinas and municipalities for operations. The scanning runs around the clock against the same measured data shown on every page.
Where Nibi comes from
Nibi means water in Anishinaabemowin. The platform began at a family cottage on Lake Muskoka, Ontario, where the spring melt floods the shoreline most years and the only forecast was standing on the dock, looking, and guessing. It grew into an independent, member-funded platform run by Muskoka Research Inc. - no investors, no data resale, and a privacy policy shorter than most cookie banners. The core data is free for everyone, forever; paid plans add automation like multi-location alerts, deep history, and reports.
Coverage
Nibi spans the continent: every Canadian province and territory with active federal gauges - from Vancouver Island rivers to the Muskoka lakes, prairie reservoirs, and Quebec's hydrometric network - and the United States from Maine to the Texas Hill Country, the Ohio Valley, and the Pacific Northwest. Coverage grows where the water news is: when a basin floods, its gauges join the platform with their full historical records attached. Many stations report every five to fifteen minutes; most report at least hourly; every page states exactly when its gauge last spoke.
Free forever, funded by members
The core promise is simple: the water data is free, for everyone, forever. Live levels, maps, radar, and recent history never sit behind a paywall. Paid plans fund the platform by adding automation - multi-location alerts, decades of history, longer forecasts, and PDF reports - so the people who need more carry the cost for everyone who just needs to check the lake before driving up. There are no investors and no advertising deals shaping what the data says.
Water Stories
Field notes and explainers from the Nibi desk - how to read a staff gauge, what a 100-year flood actually means, how snowpack becomes summer water.
The largest lake in Norway read under 8 metres for decades and reads over 120 today. The water did not move; the ruler did. What the zero of a gauge is, why a record only means something on one reference, and what we do when the zero moves.
There was no rain. A slab of glacier let go above the Trishuli, and a river gauge reading normal at 8:40 was silent by 8:50. What a river network can see coming, what it cannot, and what warning has to look like when the water outruns the news.
For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
