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.

Right Branch Lawai Stream near Umauma Road, Kauai Water Level

Live river level, flow, historical records and forecast for Right Branch Lawai Stream near Umauma Road, Kauai in HI, United States, built from official government gauge data.

About Right Branch Lawai Stream near Umauma Road, Kauai

Right Branch Lawai Stream - A vibrant channel threading through Kauai's lush landscape.

The Right Branch Lawai Stream near Umauma Road provides a glimpse into the dynamic hydrology of Kauai, Hawaii. This river, known for its rapid response to rainfall, exemplifies the tropical island's intense weather patterns, where flash floods can build in minutes due to summer storms or trade winds. With no snowmelt season to temper flow, the stream's behaviour is intricately tied to the region's rainfall, a vital factor for both the ecosystem and local communities.

The watershed context

The stream is situated within the Kauai watershed, which features several nearby water bodies including the East Branch of the NF Wailua River and the Hanalei River. These connections highlight the interactive nature of Kauai's waterways, forming a network that supports both wildlife and agricultural activities. Surrounding lush vegetation enhances the watershed's capacity to absorb rainfall, allowing for replenishment of groundwater and surface flow that sustains the local ecosystems.

Particularly during periods of intense rain, residents and visitors alike can witness how swiftly water levels rise, underlining the importance of being vigilant in this environment characterized by abrupt changes. Local streams like the Right Branch Lawai are integral, as they collect run-off and contribute to Kauai’s ecosystem resilience by nurturing diverse flora and fauna.

Why the data matters here

Today’s measurements from the Right Branch Lawai Stream indicate its current conditions relative to historical data published by the U.S. Geological Survey (USGS). Understanding today's reading against the median for this calendar day across five years of records provides a crucial context for gauging current flow conditions. This comparison offers a more nuanced perspective than simply looking at elevation numbers alone, allowing for better preparedness and anticipation of changes in this vibrant stream environment.

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.
