Nibi Metrics

Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.

Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

Water Stories

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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

Dairy Creek above Tsotin Lake Water Level

Live river level, flow, historical records and forecast for Dairy Creek above Tsotin Lake in Canada, BC, Canada, built from official government gauge data.

About Dairy Creek above Tsotin Lake

Dairy Creek - A dynamic stream above Tsotin Lake.

Dairy Creek flows robustly through the Thompson - Mouth watershed in British Columbia, feeding into the tranquil Tsotin Lake. This creek is an important component of the local hydrology, reflecting the seasonal changes inherent to mountain rivers. The gauge here serves not only to monitor water levels but also to glean insights on the health and behavior of the creek.

The watershed context

Draining roughly 11.2 square kilometres, Dairy Creek is part of a region shaped by complex mountain hydrology, where the snowpack melts, influencing water availability from spring into summer. The typical freshet begins as the snow begins to melt, generally peaking from May to July, resulting in increased flow rates during this time. Neighbouring streams such as Arrowstone Creek and the Bonaparte River join Dairy Creek in this vibrant watershed, which is characterized by its mountain landscape and seasonal variability.

Why the data matters here

Today's reading from the Dairy Creek gauge provides crucial information for local stakeholders, including cottagers, anglers, and farmers, all of whom depend on the creek's health for their activities. Understanding the current water level in relation to historical data—particularly today’s measurement compared to the median for this date across 24 years—offers a clearer picture of how the creek is performing within its usual range. Monitoring by the Water Survey of Canada (WSC) emphasizes the creek's significance and the importance of maintaining balance in this dynamic ecosystem.

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.
