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 Rio Ruidoso at Hollywood

Rio Ruidoso - An essential waterway flowing through the arid southwest.

The Rio Ruidoso, located in the state of New Mexico, presents an essential hydrological feature in an otherwise arid region. Flowing through a catchment area of approximately 120 square miles, this river serves as a vital resource for local ecosystems and communities. It is part of the broader Rio Hondo watershed and is notable for its seasonal variability driven primarily by high-country snowmelt and summer monsoon rains.

The watershed context

The Rio Ruidoso is a key tributary of the Rio Hondo, interspersed with several peers that also contribute to the region’s hydrology. Nearby waterways include Eagle Creek below South Fork near Alto and Gavilan Canyon at Skunk Canyon near Hollywood, demonstrating the interconnectedness of this river system. The river's flow is impacted by the unique hydrological patterns of the arid southwest, which typically experience long stretches of dry weather punctuated by spring runoff from melting snow and intense monsoon rainfall from July to September. These weather patterns often lead to flash flooding events, significantly affecting the flow characteristics of the river.

Why the data matters here

The data gathered by the U.S. Geological Survey at the Rio Ruidoso at Hollywood serves to inform local residents and stakeholders about current river conditions. Today's reading is crucial as it is compared to the median level for this calendar day over the past fifty years. Understanding where the current flow sits in relation to this historical average enables better preparedness for flooding or drought conditions, providing context for anglers, cottagers, and local farmers who rely on stable water levels. This comprehensive understanding of river conditions is essential for managing resources and ensuring the vitality of this important waterway.

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.
