About Mahoning Creek at Mahoning Creek Dam

Mahoning Creek in the Middle Allegheny-Redbank watershed, Pennsylvania.

What the record shows

The record on this station runs for more than 50 years.

The highest level in the file is 7.56 ft (2.31 m), set in September 2018. The lowest is 1.33 ft (0.41 m), set in September 2024. That spread matters on a small water like this: banks, access points, and any low crossing see a wide range between the calmest stretch and the years when the creek is running high.

The seasonal pattern is clear. March is the usual high month at 3.51 ft (1.07 m), while September is the usual low month at 1.94 ft (0.59 m). The typical annual swing is 18.8 in (47.8 cm). For someone keeping a dock, pump intake, or fishing spot in mind, that is the range the water works through most years.

No fastest 24-hour rise is listed here, so there is nothing to add on warning time from the record.

The watershed

The station drains 344 sq mi (891 km2) upstream of the gauge. That is the area feeding this reading, not the full watershed on a map.

This part of Pennsylvania follows a seasonal rhythm common to Appalachian and piedmont rivers: winter and spring are the main high-water seasons, and summer tends toward lower flow. Late-summer storms can still bring sharp increases, so a low September reading does not mean the creek stays there.

Reading the hero number

The hero number on this page should be read against the median for this calendar day, not as a stand-alone elevation. A water level by itself can look ordinary or alarming until you compare it with what Mahoning Creek usually carries on the same date.

That comparison is especially useful on a station with more than 50 years on record. It tells you whether today sits near the middle of the historical range, or whether it is unusually high or low for the season.

The source for this station is the USGS.

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
