Live river level, flow, historical records and forecast for Warm C near San Bernardino CA in CA, United States, built from official government gauge data.
Warm C is in the Santa Ana watershed in California.
This station sits in a stream with a small spread through the year: the typical high month is March at 1.11 ft (0.34 m), and the typical low month is October at 1.05 ft (0.32 m). That is a narrow seasonal swing of 0.7 in (1.8 cm), so day-to-day changes matter more than the calendar shape for anyone reading a gauge, planning a crossing, or watching a bank line.
For the broader season pattern, the regional setting follows Sierra snowmelt in spring and early summer, with winter storm floods and very dry summers. At this site, the record matches that general rhythm only partly in the numbers available here: the highest recorded level came in February 2024, and the lowest came in June 2021.
The record high is 2.07 ft (0.63 m) in February 2024. For a small stream, that is the kind of peak that can change access and safety quickly, especially where the channel is confined.
The record low is 0.66 ft (0.2 m) in June 2021. Low water like that is where shallow riffles, intake screens, and crossing points become more sensitive to small additional drops.
No fastest 24-hour rise is listed here, so there is no basis to describe warning time from the data provided. The drainage area above this station is 11 sq mi (28.5 km2), which is the area feeding the gauge, not the whole watershed.
The hero number on this page is best read as today’s water level compared with the median for the same calendar day across the station record. That is more useful than raw elevation alone because it tells you whether the stream is running high or low for this date, not just where the staff gage sits.
This station is operated by the U.S. Geological Survey, and it has more than 50 years of record.
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.
