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 Paauau Gulch at Pahala
Paauau Gulch - A vital waterway in Hawaii's dynamic landscape.
Paauau Gulch, nestled in the lush topography of Pahala, is an important river that showcases the distinctive hydrology of tropical islands. Fed primarily by rainfall, it’s a narrow waterway that can respond rapidly to weather events, underscoring the region’s vulnerability to flash floods. With an upstream drainage area of roughly 1.7 square miles, this gulch captures rainfall-off both the surrounding terrain and storm patterns that sweep through the islands.
The watershed context
Paauau Gulch is part of the larger Hawaii watershed, characterized by its unique climatic and hydrological features. The tropical rainfall here drives the water flow, with both the trade winds and Kona storms influencing the hydrological patterns. Tropical storms can lead to rapid increases in water levels, as the steep short basins can rise almost overnight. Along with its peers—such as Alakahi Stream and Hakalau Stream—this waterway contributes to the intricate network of streams and rivers that define the island’s landscape.
Why the data matters here
Monitoring the flow and water levels at Paauau Gulch is crucial. Today's reading is provided by the U.S. Geological Survey; when compared to the median for this calendar day across the station's 50-year historical record, this data offers a clearer picture than just raw elevation figures. This approach helps residents and stakeholders understand not just the current conditions, but also how these conditions fit within broader trends, enabling better planning and response to potential flooding events.
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.
