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 W Walker River at Hoye Brg near Wellington

W Walker River - a resilient waterway of the West Walker Valley.

The W Walker River, flowing at Hoye Bridge near Wellington, captures the spirit of the Great Basin's unique hydrology. Draining a catchment area of approximately 497 square miles, this river is influenced by the seasonal rhythms of snowmelt from the surrounding mountains, especially in spring, leading to peak flows. The summer thunderstorms characteristic of the region can trigger sudden flash floods, shaping the landscape and providing vital water resources during the hotter months.

The watershed context

Nestled within the West Walker watershed, the W Walker River serves as a critical artery within this arid environment. This watershed is home to various tributaries and waterways, each contributing to the ecological balance and historical significance of the area. Nearby channels, such as the Topaz Canal below the Walker River and Topaz Lake, highlight the interconnectedness of water systems in this region emphasizing the importance of careful monitoring and management.

Why the data matters here

Today’s reading from the US Geological Survey indicates the flow of the W Walker River at this station compared to the historic median for this calendar day over the past 50 years. Understanding how present conditions relate to historical patterns provides valuable context, helping local anglers, farmers, and residents gauge current and upcoming water conditions. As evapo-transpiration and limited summer rainfall impact water levels, this real-time data becomes crucial for those depending on the river's resources.

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.
