Live river level, flow, historical records and forecast for Missouri River below Hauser Dam near Helena MT in MT, United States, built from official government gauge data.
The Missouri River below Hauser Dam near Helena sits in the Upper Missouri watershed, Montana.
This station has about 32 years on record.
The highest level in the record is 11.07 ft (3.37 m), set in July 2011. The lowest is 3.01 ft (0.92 m), set in July 2013. That spread is a wide one for anyone watching a dock, bank edge, or intake: the river has reached well above its low-water mark, and it has also fallen much lower in summer than many people would expect.
The seasonal pattern is steadier than the records. June is the typical high month at 4.84 ft (1.48 m), while November is the typical low month at 3.7 ft (1.13 m). The typical annual swing is 13.7 in (34.9 cm). For a river user, that means the level usually changes within a modest band through the year, but the record shows larger departures can happen.
The fastest 24-hour rise is not listed here, so there is no short-term rise figure to use for warning time.
This reach belongs to the Upper Missouri watershed, and the station is on the river below Hauser Dam near Helena. In this part of Montana, the broad seasonal rhythm is shaped by spring melt and, later, summer storms. The record here fits that pattern only partly: June is the typical high month, but the highest record is in July 2011, and the lowest record is also in July 2013.
For cottagers, anglers, and anyone with shoreline equipment, the main takeaway is the range between the typical June and November levels, then the much wider spread shown by the record high and low. That is the span a berth, bank access, or low crossing has to handle over time.
The number shown at the top of the page should be read against the median for this calendar day at this station, not against the raw water level by itself. That comparison tells you whether the river is running higher or lower than usual for today, which is more useful than elevation alone.
USGS operates this station. With about 32 years on record, the daily median gives the best quick check for where the river stands relative to its own history.
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 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.
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.
