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 Puohokamoa Str ab Spreckels Ditch, Maui
Puohokamoa Stream - A vital tributary shaping Maui's landscape.
Nestled in the lush environment of Maui, Puohokamoa Stream flows as an essential waterway, characterized by rapid responses to rainfall in the steep terrain of the island. This river, situated above Spreckels Ditch, serves as a crucial aspect of Maui’s intricate hydrological system, one that thrives in a tropical climate where rainfall drives its dynamics.
Why the data matters here
The measurement station, managed by the U.S. Geological Survey (USGS), plays a pivotal role in monitoring flow and water conditions. Puohokamoa Stream drains an area of approximately 2.2 square miles (or roughly 5.7 square kilometers), which supports its quick hydrological reactions to changing weather patterns. Given the tropical island’s absence of snowmelt and reliance on rainfall, understanding this river’s flow is key to managing the flash floods that can occur in steep basins during heavy rain events influenced by trade winds and storms.
This station has been collecting valuable data for over three years, providing a historical context that helps gauge current readings and assess water levels. Today’s reading is compared against the median for this calendar day, offering a clearer picture of how the stream is performing in relation to its historical norms. This approach is vital, as raw elevation figures do not fully capture changes in flow dynamics, especially in a region where conditions can shift rapidly. Monitoring stations like the one on Puohokamoa Stream are crucial for those who live and work in these vibrant ecosystems, helping to inform on safety, water quality, and irrigation needs in Maui.
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.
