Surprise Creek near the Mouth Water Level

Live river level, flow, historical records and forecast for Surprise Creek near the Mouth in BC, Canada, built from official government gauge data.

About Surprise Creek near the Mouth

Surprise Creek in the Upper Nass watershed, BC, is monitored at 08DA005 near the mouth.

Season by season

The creek usually peaks in June at 1.46 m (4.79 ft), then eases to a typical March low of 0.74 m (2.43 ft). That 71.8 cm (28.3 in) annual swing is the part a dock, crossing, or intake has to live with: the same channel can sit nearly a metre apart between late winter and early summer.

For people watching water levels, that means June is the time to expect the highest stages, while March is the usual low-water checkpoint. If you fish or work near the banks, the shift from 1.46 m (4.79 ft) to 0.74 m (2.43 ft) is a real change in shoreline reach and current depth.

Records and rises

The highest level in the record is 2.07 m (6.78 ft), set in June 2021.

The lowest level in the record is 0.49 m (1.6 ft), set in March 2011.

Those records sit above and below the usual seasonal range, so this station has seen both a freshet-season high and a sharp low-water year. The fastest 24-hour rise is not available in the record here, so there is no published warning-time figure to add for a sudden jump.

Reading the hero number

The hero number on this page compares today’s reading with the median for this calendar day across the station’s record. That is more useful than raw elevation because 1.20 m (3.94 ft) can mean very different things in March and June.

At this site, Water Survey of Canada data give that context over more than 58 years on record. The comparison shows whether Surprise Creek is running high or low for the season, not just where it sits against the gauge zero.

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.

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.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
