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 La Sa Fua River near Umatac, Guam
La Sa Fua River - A vital stream in tropical Guam.
The La Sa Fua River runs near Umatac, Guam, embodying the dynamic hydrology characteristic of tropical Pacific islands. With a drainage area of approximately one square mile, this river plays an important role in the local ecosystem, receiving rainfall-driven input that can lead to rapid changes in flow, particularly during the wet season. The Guam region generally experiences pronounced wet and dry seasons, highlighting the variability of water availability throughout the year.
The watershed context
The La Sa Fua River is part of the broader Guam watershed, which includes several neighboring rivers such as the Almagosa River, Fena Dam Spillway, Maulap River, and Ugum River. Each of these waterways contributes to the unique hydrological character of the island. The steep terrain and short basins common to Guam can lead to flash flooding, especially during intense rainfall events or typhoons. Understanding the flow and levels of the La Sa Fua River allows local residents and authorities to monitor these changes and respond to flooding risks effectively.
Why the data matters here
Monitoring data is essential for both residents and decision-makers in Guam, helping them prepare for the extremes of seasonal rainfall patterns. Current readings from the United States Geological Survey (USGS) allow for real-time assessment of the river’s flow and height, offering insight into potential flooding or drought conditions. Today’s reading for La Sa Fua River is compared against the median for this date over the historical record of 50 years. This comparison provides a necessary context for understanding the river's current status, as it reflects the typical behavior of the river, crucial for effective management and community safety.
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.
