About Greens C at Greens Creek Mine near Juneau AK

Greens Creek near Juneau sits in the Admiralty Island watershed, Alaska.

What the record shows

The station record runs back more than 37 years.

The high-water mark is 19.45 ft (5.93 m), set in January 2013. The low-water mark is 0.88 ft (0.27 m), set in April 2009.

The seasonal pattern is fairly tight compared with those extremes. June is usually the highest month at 2.1 ft (0.64 m), while March is usually the lowest at 1.15 ft (0.35 m). That typical annual swing is 11.4 in (28.9 cm).

For anyone using the creek, that means the day-to-day range is modest most of the time, but the record shows the water can move far outside its usual band.

The watershed

The station drains 8.9 sq mi (23.1 km2) upstream of the gauge.

This is the area that feeds the reading here, not the whole named watershed on the map. In practical terms, the gauge reflects what happens in that upstream catchment, so local rain and melt in that basin are what matter first to a dock, crossing, or intake below the station.

The seasonal note for this region is simple: spring breakup and snowmelt drive the annual flood, and deep winter low flows are common. The June high and March low fit that broad pattern, but the record also shows a January peak and an April low, so the station has seen water levels outside the usual seasonal shape.

Reading the hero number

The hero number on this page compares today’s reading with the median for this calendar day across the station record.

That is more useful than raw elevation because the same number can mean very different things at different times of year. A level that is ordinary in one month may be high or low in another. The calendar-day median gives the better quick read on whether the creek is running near its usual range right now.

This station is operated by the USGS, and the record spans more than 37 years.

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 17,900+ lakes and rivers

Real-time water levels, forecasts, and alerts for lakes and rivers in a growing number of countries. Built on official government data.

Nibi Metrics tracks more than 17,900 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's water monitoring network, and on the Great Lakes the Canadian Hydrographic Service and NOAA. 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.

Water Stories

Field notes and explainers from the Nibi desk - how to read a staff gauge, what a 100-year flood actually means, how snowpack becomes summer water.

The lake that did not rise 117 metres

The largest lake in Norway read under 8 metres for decades and reads over 120 today. The water did not move; the ruler did. What the zero of a gauge is, why a record only means something on one reference, and what we do when the zero moves.

The flood that came on a clear day

There was no rain. A slab of glacier let go above the Trishuli, and a river gauge reading normal at 8:40 was silent by 8:50. What a river network can see coming, what it cannot, and what warning has to look like when the water outruns the news.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
