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.

Pecos River below Sumner Dam Water Level

Live river level, flow, historical records and forecast for Pecos River below Sumner Dam in NM, United States, built from official government gauge data.

About Pecos River below Sumner Dam

Pecos River below Sumner Dam - A vital artery in the high desert landscape.

The Pecos River below Sumner Dam winds through the arid terrain of New Mexico, harnessing the region's seasonal rhythms to sustain its flow. This river plays a critical role in the Upper Pecos watershed, providing water to a diverse range of ecosystems and surrounding agricultural activities.

The watershed context

Draining roughly 4,390 square miles above the station, the Pecos River below Sumner Dam reflects the dynamic and sometimes harsh hydrology of the region. The majority of the flow is influenced by seasonal snowmelt from the higher elevations, particularly in spring. As temperatures rise, runoff from the melting snow contributes to increased water levels, crucial for maintaining the river's ecology.

During the summer months, from July to September, monsoon storms can bring heavy rains that may lead to flash floods. This peak in flow can contrast sharply with long, dry stretches where precipitation is sparse, highlighting the extremes of arid Southwest hydrology.

Why the data matters here

Monitoring water levels at the Pecos River below Sumner Dam is important for both ecological management and agricultural planning. By comparing today’s reading to the historical median for this date, we can assess water availability and trends in the river’s health. The U.S. Geological Survey (USGS) operates this station, providing essential data for understanding the river's patterns.

Today’s water level will be compared against the median for this calendar day across more than 50 years of data. This approach offers a more meaningful insight into current conditions, reflecting the nuanced nature of hydrologic changes rather than simply noting raw elevation figures.

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.
