Finding the top signal on the water…
Live river level, flow, historical records and forecast for Warm Slough near Central City, Nebr. in NE, United States, built from official government gauge data.
Warm Slough in the Middle Platte-Prairie watershed, Nebraska, is a USGS gage in the United States.
The usual high water comes in June at 3.5 ft (1.07 m), and the usual low water comes in August at 2.32 ft (0.71 m). That is a typical annual swing of 14.1 in (35.9 cm), so the channel can look different from early summer to late summer even without a big storm. For anyone drawing water, setting a dock, or fishing a reach that changes with stage, that seasonal range is the first thing to watch.
Plains hydrology often puts the largest movements in spring snowmelt and rain floods, with summer convective storms adding short-lived jumps. In a steadier system, groundwater can hold levels up through dry periods; the seasonal pattern here is the part worth tracking before you plan a trip or work near the bank.
The record high is 87.76 ft (26.75 m), set in April 1997. The record low is 0 ft (0 m), set in November 2002. Those two ends give a wide frame for what this water can do over time.
The station does not list a fastest 24-hour rise, so there is no published warning-time number here to lean on. For flood watch, that matters: without a rise figure, the best reference is the live stage itself and how quickly it departs from the usual June and August levels.
The hero number on this page is today’s reading compared with the median for this calendar day across the station record. That is more useful than raw elevation because it shows whether the water is running above or below its normal seasonal position for this date.
This station has more than 30 years on record, so the daily median has some history behind it. For people watching access points, bank exposure, or shallow-water habitat, that calendar-day comparison is the quickest way to judge whether the slough is behaving normally for the season.
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.
