James River near Mitchell Water Level

Live river level, flow, historical records and forecast for James River near Mitchell in SD, United States, built from official government gauge data.

About James River near Mitchell

The James River near Mitchell sits in the Lower James watershed in South Dakota.

The watershed

This station drains 19,088 square miles (49,438 km2) upstream of the gauge. For nearby landowners and river users, that is the area whose runoff can show up here, not the whole Lower James at once.

What the numbers say

The record high here is 25.03 ft (7.63 m), set in June 2010. The record low is 9.24 ft (2.82 m), set in August 2021. Those two marks show the range this reach can move through over the record.

The seasonal pattern is clear. July is the highest typical month at 14.21 ft (4.33 m), while February is the lowest typical month at 10.43 ft (3.18 m). The typical annual swing is 3.8 ft (1.15 m). For docks, banks, intakes, and low crossings, that is the band to plan around through the year.

The watershed note for this part of the Plains is spring snowmelt first, with sharp rises on frozen ground, then summer convective storms and a long recession. That rhythm fits the main hazards people watch for here: quick moves in spring, then shorter pulses in summer, and a slower slide through the rest of the season.

Reading the hero number

The number shown on this page is best read against the median for this calendar day, not against the full-scale elevation. A raw level by itself says little unless you know what is normal for this date at this station.

This is a USGS station with more than 25 years on record. Compare today’s reading to the calendar-day median to see whether the river is running above its usual range for this time of year, or below it, which is the better cue for boating, access, and water use.

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

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.
