About St Clements Creek near Clements
St Clements Creek is in the Lower Potomac watershed in Maryland.
What the record shows
The USGS record for this creek goes back more than 50 years. The highest water in that record was 5.59 ft (1.7 m) in August 2011. The lowest was -0.91 ft (-0.28 m) in June 2026.
The seasonal pattern is narrower than those extremes. March is the usual high month at 1.14 ft (0.35 m), while September is the usual low month at 0.4 ft (0.12 m). That typical annual swing is 8.9 in (22.5 cm).
For anyone with a dock, shallow launch, or intake, the record says two things: the creek can run well above its usual level in late summer, and it can also sit close to its seasonal low in early fall. Without a fastest 24-hour rise on record, there is no published short-term warning pace to lean on here.
The watershed
The station drains 18.5 sq mi (47.9 km2) upstream of the gauge. That is the area that feeds this reading, not the whole Lower Potomac watershed.
In this part of Maryland, winter and spring rain floods are the main seasonal pattern, and tropical remnants are the events that can push water to the top of the record. Summer is usually the lower-flow season between storms. The creek’s monthly cycle fits that general rhythm: higher in March, lower in September.
For local users, that means the channel is most likely to be running higher when banks and access points are already dealing with wetter ground, and most likely to be low when late-season heat and evaporation have had time to work on it.
Reading the hero number
This page’s hero number should be read against the median for the same calendar day, not as a stand-alone elevation. The daily median shows whether the creek is high or low for this date in its own record, which is more useful than a single level by itself.
This is a USGS station, and with more than 50 years on record, that calendar-day comparison gives a better sense of where the creek sits relative to its usual seasonal range.
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.
