Finding the top signal on the water…
Live river level, flow, historical records and forecast for Big Bear Creek at Ladora in IA, United States, built from official government gauge data.
Big Bear Creek at Ladora is a river in the Middle Iowa watershed, Iowa.
The pattern here is steady enough to plan around, but not flat. May is the typical high month at 12.07 ft (3.68 m), and September is the typical low month at 10.87 ft (3.31 m). That typical annual swing is 14.4 in (36.7 cm), so the water level usually moves within a fairly tight band from spring into late summer.
For anyone with a dock, pump intake, or low crossing nearby, that means the bigger changes tend to come in the warm-up season and then ease back toward late summer. In prairie-midwest hydrology, spring snowmelt and rain on frozen or saturated ground are the main flood season, while summer storm rises can still move water fast.
The area above this station is 189 sq mi (490 km2), so the gauge is watching a moderate upstream basin rather than the whole watershed.
The highest level in the record is 25.95 ft (7.91 m), set in July 2014. The lowest is 10.1 ft (3.08 m), set in April 2024.
That span tells you this creek can sit close to its seasonal low and still leave room for a large rise when conditions line up. The station’s record years go back 50 years, so these extremes sit inside a long local record rather than a short burst of data.
No fastest 24-hour rise is listed in the facts, so I won’t guess at warning time.
The hero number on this page is best read as today’s level compared with the median for this calendar day, not just as an absolute elevation. Raw height alone can hide whether the creek is running high for the season or sitting near its usual daily range.
This station is operated by the USGS, and the record spans about 50 years. That longer record gives the median its value: it anchors today’s reading to what is normal for this date on Big Bear Creek, not just to one number on the staff.
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.
