About Bryant C below Mountaineer C near Markleeville CA
Bryant Creek in the Upper Carson watershed in California.
What the record shows
Over more than 28 years of record, the highest level was 6.16 ft (1.88 m) in May 2023, and the lowest was 3.67 ft (1.12 m) in July 2014. That span matters for anyone watching a bank, culvert, pump, or access crossing: the creek has shown a clear range between late-spring highs and midsummer lows.
The usual seasonal pattern peaks in April at 4.11 ft (1.25 m) and drops to 3.85 ft (1.17 m) in August. The typical annual swing is 3.1 in (7.9 cm). For a small creek, that is a modest but useful change to know if you keep equipment near the edge or fish the same reach through the warm months.
The watershed
This station is on a drainage area of 21.4 sq mi (55.4 km2) upstream of the gauge. The USGS site sits in the Upper Carson watershed, and the record here reflects what reaches this point above the station, not the larger watershed as a whole.
For the region, the seasonal rhythm is straightforward: spring and early summer are the higher-flow months, then flows ease through the long dry season. In this record, the April high and August low fit that pattern. When planning around the creek, that seasonal shape is often more useful than a single day’s reading.
Reading the hero number
The hero number on this page is best read as today’s level compared with the median for this calendar day at this station. That tells you whether the creek is running above, near, or below its usual place for the date, which is more useful than a raw elevation by itself.
USGS is the operating agency here. With more than 28 years on record, the station gives a solid baseline for seeing whether today is typical, high for the season, or trending low.
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.
