About Gunnison River near Grand Junction, CO.
Gunnison River near Grand Junction sits in the Lower Gunnison watershed in Colorado.
What the record shows
The station record spans more than 50 years, and the range is wide enough to matter for banks, pumps, and river access.
The highest level in the record was 11.99 ft (3.66 m) in May 2023. The lowest was 2.4 ft (0.73 m) in July 2026. That is a large spread for anyone setting a dock, watching an intake, or planning a launch.
The typical seasonal high comes in May at 3.64 ft (1.11 m), while the typical seasonal low comes in February at 2.64 ft (0.81 m). The typical annual swing is 12 in (30.5 cm). For a river user, that means spring conditions are usually the most demanding, while winter tends to sit lower and tighter.
The watershed
The gauge drains 7923 sq mi (20521 km2) above this station. That is the area feeding the reading here, not the full watershed name on a map.
For this reach, the seasonal rhythm fits snowmelt-dominated mountain hydrology: a pronounced May-June peak, then lower water later in the summer and a long low-flow winter. July and August thunderstorms can still bring sharp local rises. Those short-lived jumps are the kind that can change a crossing, shoreline, or fishing spot quickly even when the season is otherwise moving low.
Reading the hero number
Today’s reading is best judged against the median for this calendar day in the station record, not against the river’s absolute elevation. A single stage number by itself does not tell you whether the river is high or low for this date; the daily median does.
This station is operated by the USGS. With more than 50 years on record, the calendar-day comparison gives the most useful context for day-to-day use on the river.
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 lakes and rivers across Canada, the US and the UK
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada, the US and the UK. Built on official government data.
Nibi Metrics tracks more than 13,000 gauged lakes and rivers across Canada, the United States and the United Kingdom, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, and the Environment Agency for England. 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.
