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.

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 Carlsbad Main Canal at Head near Carlsbad

Carlsbad Main Canal - An essential channel in the arid southwest.

The Carlsbad Main Canal at Head near Carlsbad, New Mexico, serves as a significant waterway within the Upper Pecos-Black watershed. This canal plays a crucial role in irrigating the arid landscape, showcasing the adaptability of the region's water management in the face of challenging climatic conditions.

The watershed context

While the specifics of the drainage area upstream of the Carlsbad Main Canal are not available, it is instrumental to consider the surrounding context of the Upper Pecos-Black watershed. This area encompasses a network of rivers, including the impressive Black River, which flows close by and provides vital connectivity for the region’s water resources. Peers such as Black River above Malaga and Blue Springs offer additional hydrological insight and highlight the intricate relationships among the waterways in this part of New Mexico.

Typically, the hydrology in this arid southwest region is markedly influenced by seasonal patterns. High-country snowmelt is key to spring flows along the major rivers, and the summer months often bring intense monsoon storms that can lead to rapid runoff and flash flooding. These conditions underscore the necessity for effective management of the water resources in the area, as the long dry stretches between rainfall dictate a limited water supply for agricultural and municipal needs.

Why the data matters here

Data from the Carlsbad Main Canal is collected by the U.S. Geological Survey (USGS), which also measures discharge rates—essential for understanding the flow dynamics in this essential irrigation canal. On any given day, comparing today's reading to the median for the same calendar day across the station's historical records (over 50 years of data) provides critical insights. This context is more informative than raw elevation alone as it reflects how current conditions deviate from the norm, enabling better decision-making for water usage and management.

By keeping track of these variations, local farmers, landowners, and water managers can make informed choices regarding irrigation practices, especially during the variable summer months. Thus, the data monitoring not only sustains agricultural productivity but also supports the health of the broader ecosystem in this arid setting.

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.
