Live river level, flow, historical records and forecast for Potlatch River Bel Little Potlatch CR near Spalding in ID, United States, built from official government gauge data.
The Potlatch River Bel Little Potlatch CR near Spalding is in the Clearwater watershed, Idaho.
Spring is the main rising season here. The highest typical month is March at 8.22 ft (2.51 m), and the record high also came in March 2026 at 15.33 ft (4.67 m). For anyone watching a dock, pump, or bank access, that says this reach can sit well above its late-summer level before the main snowmelt period is over.
By August, the river is usually at its lowest. The typical level then is 3.95 ft (1.2 m), and the record low was 2.94 ft (0.9 m) in August 2015. The typical annual swing is 4.3 ft (1.3 m), so seasonal setup and cleanup should leave room for that range.
The record high of 15.33 ft (4.67 m) in March 2026 is the clearest high-water mark in the station record. The record low of 2.94 ft (0.9 m) in August 2015 sets the low-water end.
There is no fastest 24-hour rise value in the facts provided, so I will not fill that in. That means I cannot give you a day-ahead warning figure from this page alone; for flood watching, the short-term change rate is the number that tells you how quickly conditions can shift.
The hero number on this page should be read against the median for this calendar day, not as a raw height by itself. A level can look high or low without context; the calendar-day median shows whether today is above or below what this station usually sees at this time of year.
This station is a USGS site, and the record spans 23 years. For cottagers, anglers, and anyone with an intake or crossing near the bank, that comparison is the useful part: it tells you where today sits within the local seasonal pattern, not just where the water surface happens to be.
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.
