Live river level, flow, historical records and forecast for Chillisquaque Creek at Washingtonville in PA, United States, built from official government gauge data.
Chillisquaque Creek at Washingtonville sits in the Lower West Branch Susquehanna watershed in Pennsylvania.
March is the typical high-water month here, with a median level of 1.28 ft (0.39 m). September is the typical low-water month, with a median level of 0.74 ft (0.23 m). That seasonal swing is 6.4 in (16.2 cm), so the creek usually asks docks, crossings, and intakes to handle a modest but real change through the year.
For people living along the creek or fishing it, that pattern says spring is the time to watch for higher water, while late summer is when levels tend to be lowest. The regional pattern fits that general rhythm: winter-spring rain and melt build the annual peaks, and summer low flows are part of the normal cycle.
The highest water in the record came in September 2011 at 9.78 ft (2.98 m). The lowest was in August 2025 at 0.15 ft (0.05 m). With 47 years on record, those two readings bracket a wide range for the same channel.
A high like the September 2011 mark is the kind of level that can matter at crossings and low banks. A low like the August 2025 mark is the kind of level that can limit depth over shallow riffles and around intakes. No fastest 24-hour rise is listed for this station, so there is no number here to use as a warning-time guide.
The hero number on this page is today’s reading set against the median for this calendar day across the station record. That is more useful than raw elevation because a given height means different things in March and in September.
This station is operated by the USGS, and it has more than 47 years of record behind it. If today’s reading sits above the daily median, the creek is running higher than usual for this date; if it sits below, it is running lower than usual. That is the quick read that matters for access, fishing, and flood watch.
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.
