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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Pecos River above Santa Rosa Lake

Pecos River above Santa Rosa Lake - a vital flow in New Mexico's dry landscape.

The Pecos River, coursing above Santa Rosa Lake, is a crucial waterway in the arid Southwest. This river is part of the Pecos Headwaters watershed, which encompasses a significant drainage area of approximately 2,340 square miles upstream of the measurement station. The arid conditions in New Mexico shape the river's character, with high-country snowmelt kickstarting flows in the spring and intermittent flash floods becoming a hallmark during the monsoon season from July to September.

The watershed context

The Pecos River's watershed is diverse, connecting with various peers including Beaver Creek and Gallinas Creek, each contributing to the hydrology of the region. The surrounding area experiences long dry spells punctuated by brief, intense rainfall events. This seasonal rhythm influences not only the river's flow but also the broader ecosystem that relies on these water resources for survival.

Why the data matters here

Today's measurement of the Pecos River above Santa Rosa Lake is vital for understanding local conditions. The current water level relative to the historical median for this date provides insight into current flow patterns against a backdrop of over 50 years of recorded data. When evaluating river health, comparing today's level with the historical median, published by the U.S. Geological Survey (USGS), is more informative than a raw elevation number. It reflects how today's conditions stack up against typical levels, allowing cottagers, anglers, and others interested in water resources to monitor potential changes in this vital ecosystem.

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.
