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 San Juan River at Shiprock

San Juan River at Shiprock - A vital artery in New Mexico's arid landscape.

The San Juan River flows through the heart of Shiprock, New Mexico, serving as a critical water source in an otherwise arid environment. This stretch of the river, characterized by dramatic landscapes and vital ecosystems, is shaped by the seasonal rhythms of the Southwest. It plays an essential role in the surrounding community, supporting both agricultural practices and natural wildlife habitats.

The watershed context

The San Juan River is part of the Middle San Juan watershed, draining approximately 12,900 square miles. It is bordered by tributaries such as the La Plata River, which brings additional water contributions that enrich this significant river system. The seasonal patterns of the regional hydrology greatly influence water levels here, as high-country snowmelt typically drives flows in the spring months. Additionally, from July to September, the area is subject to monsoonal storms that can result in flash floods, which significantly affect flow dynamics. During long dry stretches, water levels can recede, creating a challenging environment for users relying on this resource.

Why the data matters here

Monitoring the San Juan River at Shiprock is essential for understanding and managing water resources in this crucial area of New Mexico. The U.S. Geological Survey (USGS) station at this location not only measures the river's elevation but also tracks its discharge, providing invaluable data to help inform water management decisions. Today's reading is compared to the historical median for this calendar day, offering a clearer perspective on the river's current status by contextually grounding the figure against historical records accumulated over the past 50 years. Elevations fluctuate due to a mix of natural variability, seasonal patterns, and regional climate influences, making this data crucial for local farmers, community planners, and environmental managers alike.

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.
