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.
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.

Live river level, flow, historical records and forecast for Riviere Des Rochers above Slave River in Canada, AB, Canada, built from official government gauge data.
Riviere Des Rochers - A vital tributary of the Upper Slave watershed.
Riviere Des Rochers flows gracefully, contributing its waters to the Upper Slave watershed in Alberta. This river, while not part of any major system of gauged flows, represents an important natural feature in the regional hydrology, with a substantial catchment area of approximately 283,000 square kilometres draining into it.
Surrounded by the diverse terrain of Alberta, Riviere Des Rochers plays a critical role as a tributary. Though this specific reach lacks a recorded parent river, it shares its watershed with notable peers such as the Peace River below Chenal Des Quatre Fourches and other segments of Riviere Des Rochers. The river responds dynamically to natural rhythms, particularly influenced by mountain snowmelt which drives peak flows in late spring. In the summer, it can be affected by convective storms leading to sharp rises in flow.
While this station currently does not publish discharge measurements, the elevation reading of the Riviere Des Rochers is essential for understanding local hydrological patterns. Today’s elevation at this location is compared against the median for this calendar day over the past 49 years. This context is vital, as median readings can provide insightful benchmarks for current conditions, assisting local cottagers, farmers, and flood-watchers in navigating their decisions in the face of changing hydrological dynamics. This data, collected and managed by Water Survey of Canada, reflects not just prevailing conditions but also the underlying trends that shape the river’s health and influence the surrounding ecosystem.
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.
