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.

About Waiahi Str US Upper Powerhouse, Kauai
Waiahi Stream - A vital lifeline for Kauai's ecology.
Nestled in the verdant landscapes of Kauai, the Waiahi Stream at the Upper Powerhouse serves as an essential watercourse, critical for the local ecosystem and community. This river, with its catchment area of roughly 4.1 square miles, contributes significantly to the hydrology of the region, making it a noteworthy feature within Kauai’s diverse waterways.
The watershed context
The Waiahi Stream is one among many tributaries that feed the intricate web of Kauai’s watershed, which is characterized by an intricate drainage pattern shaped by the island's steep terrain. Surrounded by neighboring peers like the Hanalei River and the East Branch of the North Fork Wailua, it plays a role in the rapid response system to rainfall that the island experiences. Tropical island hydrology dictates that rain-driven events lead to swift changes in water levels, with streams and rivers often rising quickly during heavy rainfalls. This dynamic nature of island hydrology is crucial for understanding how water flows are impacted throughout the year.
Why the data matters here
Monitoring data from the Waiahi Stream, captured by the U.S. Geological Survey (USGS), provides valuable insights into how rainfall influences water levels at this gauge. With a record of data spanning over 11 years, recent measurements allow us to compare current water levels against the median for this day in the station’s historical record. Today’s reading is essential for understanding flooding potential and stream health, surpassing ratings based merely on raw elevation. Such evaluations help residents and stakeholders anticipate changes effectively, ensuring safety and informed decision-making within this vibrant community.
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.
