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 Zuni River above Black Rock Reservoir

Zuni River above Black Rock Reservoir - A vital waterway in the Zuni watershed.

The Zuni River flows through the heart of New Mexico, providing essential water resources amidst a landscape shaped by seasonal extremes. This segment of the river, located above the Black Rock Reservoir, contributes significantly to the Zuni watershed, draining approximately 848 square miles. As the river traverses this arid region, its character is influenced by the high-country snowmelt in spring, which drives the initial surge of flows.

The watershed context

The Zuni River is part of a complex hydrological system where water availability fluctuates greatly throughout the year. Following the winter snowmelt, flow can be robust, but the absence of rain during the long dry stretches often leads to diminished water levels. The summer monsoon season, occurring from July to September, has the potential to cause flash floods in the region, adding a dynamic component to the river's flow patterns. Nearby, the Rio Nutria near Ramah also plays a role in this watershed, highlighting the interconnectedness of these water bodies.

Why the data matters here

Today’s streamflow measurement at Zuni River above Black Rock Reservoir provides important context for understanding current water conditions. This reading can be compared to the historical median for this calendar day, allowing users to see how today's levels measure against long-term averages tracked over the past 50 years by the U.S. Geological Survey (USGS). Such comparisons are crucial for local farmers, anglers, and those monitoring conditions for flooding, as they provide insights into trends and variations instead of relying solely on raw elevation data. Understanding these patterns can help inform water management and conservation efforts in this vital area.

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.
