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 Ophir Creek near Steamboat

Ophir Creek - a seasonal waterway shaped by mountain snowmelt.

Ophir Creek flows through the rugged highlands of Nevada, a river characterized by its seasonal flows that rely heavily on snowmelt from the surrounding mountains. As part of the Truckee watershed, this creek plays a vital role in the local hydrology, providing essential moisture to an otherwise arid landscape. The creek serves as a reminder of the dynamic interplay between water, terrain, and the seasonal patterns that govern this region.

The watershed context

The Truckee watershed, home to Ophir Creek, is a tapestry of ephemeral streams and perennial rivers, notably influenced by the area's distinct arid conditions. With a drainage area of approximately 4.2 square miles above the station, the creek captures runoff primarily from spring snowmelt, which leads to seasonal flow peaks in late spring. This natural cycle is crucial for recharging local groundwater and sustaining the ecosystem in an otherwise dry environment, particularly vulnerable to fluctuations in water availability.

Why the data matters here

Water data from the United States Geological Survey (USGS) is vital for understanding the conditions of Ophir Creek. Today's reading, compared to the median for this calendar day across the creek's nine years of record-keeping, provides valuable insight into current water levels and flow conditions. Monitoring this data helps inform local stakeholders, from farmers to recreational users, about the health of the creek and its responsiveness to seasonal variations. Understanding how today’s elevation compares to the historical median can lead to better management and conservation efforts, ensuring that the waterway continues to support both the environment and the community.

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.
