About Lake Arthur at Moraine State Park
Lake Arthur sits in the Connoquenessing watershed in Pennsylvania.
What the record shows
The station record runs for more than 19 years.
The highest level in that record was 1192.17 ft (363.37 m) in April 2024. The lowest was 1187.11 ft (361.83 m) in February 2009. For people watching docks, ramps, or shoreline access, that spread shows how far this lake can move between wet and dry stretches.
Seasonally, April is the highest month at 1190.61 ft (362.9 m), and September is the lowest month at 1189.85 ft (362.67 m). The typical annual swing is 9.1 in (23 cm). That is not a large seasonal range, but it is enough to matter for a fixed intake, a shallow landing, or a spot where a boat trailer has little margin.
No fastest 24-hour rise is listed in the facts, so there is nothing to add on warning time from this record.
The watershed
The station drains 50.8 sq mi (132 km2) above the gauge. That is the area feeding this reading, not the whole watershed name on the map.
This part of Pennsylvania follows a pattern of winter-spring rain and melt setting the annual peaks, with summer low flows. For a lake user, that means the higher levels are more likely to arrive in the colder half of the year or in spring, while late summer often asks more of shallow access points and small docks.
Reading the hero number
The hero number on this page should be read against the median level for this calendar day, not as a raw elevation by itself. A single level tells you where the surface sits; the calendar-day median tells you whether today is typical, high, or low for this date at this station.
That comparison is the better tool for judging whether the lake is running above its usual seasonal track or below it. At a station with 19 years on record, that context matters more than the absolute number alone.
This USGS station is the source for the reading.
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.
How Nibi Metrics works · Water stories
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.
