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.

About Grouse C at Grouse Lake Outlet near Seward AK

Grouse Creek - A vital outflow from Grouse Lake.

Grouse Creek flows out from Grouse Lake near Seward, Alaska, contributing to the Resurrection River-Frontal Resurrection Bay watershed. This river plays a significant role in the area's hydrology, providing vital water flow that is particularly influenced by seasonal changes in the region.

The watershed context

The Resurrection River-Frontal Resurrection Bay watershed is characterized by its dynamic seasonal patterns, driven primarily by the subarctic climate of Alaska. Spring breakup and snowmelt typically herald the onset of higher water levels in the region, often leading to spring floods. Ice jams can be a common occurrence during this transitional period. In contrast, deep winter often sees reduced flow under ice, as groundwater contributions become the primary water source during the colder months. With a catchment area of approximately 6 square miles, Grouse Creek is a vital part of this unique hydrological system, feeding into a landscape that supports diverse flora and fauna.

Nearby water bodies, including Lowell Creek and Upper Nuka River, also showcase similar seasonal behavior as they complement one another in feeding the local ecosystem. The interplay between these waterways not only sustains the local habitat but also provides recreational opportunities for residents and visitors alike.

Why the data matters here

The continuous monitoring of Grouse Creek at its outlet is conducted by the U.S. Geological Survey (USGS), which provides valuable data on the stream's flow measurements. These readings are critical for understanding fluctuations in water levels, particularly as they relate to seasonal variations in snowfall and ice melt. Today's reading of the creek can be compared against the median data for this calendar day across nearly 30 years of records, illuminating the creek's current status in the context of its historical flow patterns. This comparison is vital; it helps to identify trends and anomalies in the stream's behavior, offering insights that can assist in managing water resources effectively and ensuring the health of local ecosystems.

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.
