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 East Fork Martin R at Mouth near Homer AK

East Fork Martin River - a key waterway in the Lower Kenai Peninsula.

The East Fork Martin River, located near Homer, Alaska, is part of the Lower Kenai Peninsula watershed. This waterway plays an important role in the local hydrology, with connections to several notable peers such as the Anchor River and Bradley River. Characterized by its subarctic hydrology, the East Fork Martin River experiences significant seasonal changes, primarily driven by spring breakup and snowmelt, which can lead to annual flooding, often complicated by ice jams.

Why the data matters here

Today's measurement from the East Fork Martin River is crucial for understanding the current water conditions in this region. While the gauge does not provide a discharge measurement, monitoring elevation is important, especially considering the river's subarctic context. The water levels can fluctuate dramatically throughout the year, making this information vital for local residents and stakeholders, including fishermen and those engaged in recreational activities.

As our hero number indicates today's water level compared to the median for this date over the last three years, we can better assess the health and activity of the ecosystem in relation to typical conditions. This reference, supplied by the U.S. Geological Survey (USGS), helps users make informed decisions, whether regarding fishing opportunities, planning trips, or understanding potential risks associated with floods or low-water conditions.

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.
