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 Rocky Arroyo at Highway Brd near Carlsbad

Rocky Arroyo - A vital stream in the arid Southwest.

Rocky Arroyo flows near Carlsbad, New Mexico, as an essential tributary in the Upper Pecos-Black watershed. This stream contributes to the regional hydrology that is shaped by the interplay between high-country snowmelt and seasonal monsoon events. With approximately 285 square miles of drainage area above the gauge, Rocky Arroyo captures rainfall and runoff, delivering water crucial for local ecology and human use.

The watershed context

The Upper Pecos-Black watershed encompasses a diverse landscape characterized by its arid conditions. Snowmelt from the surrounding high country drives flows during spring months, providing key hydration to waterways after a winter thaw. The monsoon period from July to September often leads to sudden flash floods as summer storms sweep through the region, bringing intermittent relief to long stretches of dry weather. The Rocky Arroyo serves as an important waterway within this dynamic system, flanked by other notable rivers and tributaries including the Black River and various draws in the area.

Why the data matters here

Monitoring water levels at Rocky Arroyo is significant not only for understanding its flow dynamics but also for assessing the health of the watershed overall. The U.S. Geological Survey (USGS) measures discharge here, allowing for a comprehensive view of stream behavior throughout the changing seasons. Today's reading will shed light on how Rocky Arroyo compares to historical conditions. Specifically, it is vital to look at today's water level in relation to the median for this calendar day over the past 50 years, offering context that raw elevation numbers cannot provide. Such insights help stakeholders manage local water resources effectively in this variable climate.

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.
