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 Rio Grande Floodway at San Acacia

Rio Grande Floodway at San Acacia - A key tributary in the arid landscape.

The Rio Grande Floodway at San Acacia flows through a vital channel in New Mexico, contributing to the broader dynamics of the Rio Grande-Albuquerque watershed. This river segment is significant not only for the water it carries but also for its role within the complex seasonality of southwest hydrology.

The watershed context

The Rio Grande Floodway serves as a crucial conduit for water in an area where the climate is largely defined by its arid conditions. Draining an expansive area of approximately 26,770 square miles, this floodway collects runoff and contributes to the overall water supply of the region. The seasonal patterns here are influenced predominantly by high-country snowmelt, driving spring flows, and the potential for monsoon storms from July through September, often leading to sudden flash floods. Long dry stretches separate these precipitation events, underscoring the importance of the floodway in capturing and holding water during these variable conditions.

Neighboring waterway peers, including the Rio Grande at Albuquerque and various flood channels, interact with the Rio Grande Floodway, highlighting the interconnected nature of the watershed. These channels and outfalls play significant roles in managing the flow of water that supports both ecological systems and human demand.

Why the data matters here

Current conditions at the Rio Grande Floodway are crucial for understanding water availability in this desert environment. The US Geological Survey (USGS) station here monitors not just the water level, but it also measures the flow, providing insights into how water availability fluctuates over time. Today's river reading should be understood in the context of historical data; comparing today's figure against the median for this calendar day over the station's 50 years of records showcases how current conditions stand relative to long-term averages. This temporal perspective is essential for farmers, anglers, and flood-watchers alike, allowing them to make informed decisions based on emerging trends and current water status.

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.
