Live river level, flow, historical records and forecast for North Gila Main Canal Wasteway near Yuma in AZ, United States, built from official government gauge data.
North Gila Main Canal Wasteway near Yuma sits in the Lower Gila watershed in Arizona.
The record high is 6.24 ft (1.9 m) in May 2023. The record low is 0.52 ft (0.16 m) in June 2018. That spread tells you this reach can move a lot between one extreme and the next, even though the usual seasonal range is much tighter.
The typical high point comes in November at 1.73 ft (0.53 m), while the typical low point comes in August at 1.4 ft (0.43 m). The typical annual swing is 3.9 in (9.8 cm). For anyone watching a bank, intake, or crossing, that means the everyday change is modest compared with the station’s extremes. The biggest swings are the ones that matter for surprise access issues, but the seasonal pattern itself is small.
No fastest 24-hour rise is listed here, so there is nothing in the record to point to a specific flood-warning pace.
This station is part of the Lower Gila watershed, and the gauge name matters more than the broader watershed name when you are reading the numbers. The site’s record is about this monitored reach, not the whole basin.
In an arid-Southwest setting, the monthly pattern is often more important than a single reading. Here, August is typically the low month and November the high month, so late summer is the time to watch for shallower conditions, and late fall is when the station usually sits higher. If you use the water for access, diversion, or fishing nearby, those are the months that frame the usual operating window.
The hero number on this page is today’s reading set against the median for this calendar day across the station’s record. That is more useful than raw elevation because it tells you whether the gauge is running high or low for this date, not just where it sits on the staff.
This station is published by the USGS, and the record here spans more than 50 years. A reading that is above the daily median means the water is running higher than usual for this date; a reading below it means lower than usual. That context is what helps cottagers, anglers, and water users judge whether conditions are moving toward the station’s typical range or away from it.
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.
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.
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.
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.
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.
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.
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.
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.
